    Setting it too high effectively disables the optimization because once concurrency has been detected it will keep that way. Setting it too low could lead to suboptimal performance because the system will try write through and other optimizations even though the system is concurrent.

```
public static final HazelcastProperty TCP_PREVIOUSLY_JOINED_MEMBER_ADDRESS_RETENTION_DURATION
```
    Specifies how long the address of a member that has previously joined the cluster will be retained/remembered in the TcpIpJoiner after it leaves the cluster. The remembered member addresses is used to discover other cluster by split-brain handler.
  - MULTICAST_SOCKET_SET_INTERFACE
```
public static final HazelcastProperty MULTICAST_SOCKET_SET_INTERFACE
```
    Allows explicitly control if the MulticastSocket.setInterface(java.net.InetAddress) method is called in the Hazelcast multicast discovery service. This configuration may affect the multicast behavior on some platforms. The default value is not specified here and in such case Hazelcast multicast service itself decides if the setInterface() call should be called.
  - MULTICAST_GROUP
```
public static final HazelcastProperty MULTICAST_GROUP
```
    IP address of a multicast group. If not set, then the configuration is read from the MulticastConfig configuration.

```
public static final HazelcastProperty PARTITION_FRAGMENTED_MIGRATION_ENABLED
```
    When enabled, which is the default behavior, partitions are migrated/replicated in small fragments instead of one big chunk. Migrating partitions in fragments reduces pressure on the memory and network since smaller packets are created in the memory and sent through the network. Note that it can increase the migration time to complete.
  - PARTITION_CHUNKED_MIGRATION_ENABLED
```
public static final HazelcastProperty PARTITION_CHUNKED_MIGRATION_ENABLED
```
    Enable to subdivide fragments into chunks.
    Default enabled.

    If you have parallel migrations, max migrating data equals number-of-parallel-migrations times this value.
    Default is 250 MB.
  - WAIT_SECONDS_BEFORE_JOIN
```
public static final HazelcastProperty WAIT_SECONDS_BEFORE_JOIN
```
    The time that a newly-appointed master node waits before forming a cluster. Once a cluster is being started, a newly-appointed master node may receive a flurry of join requests. If these requests were processed immediately, the master node would have the overhead of processing each join request individually and informing the existing cluster members of the membership changes. Instead, the master will wait for some time to "batch" the initial join requests. This parameter defines time that the master node will wait since the last received join request (a pre-join window) before it starts processing the join requests and forming a cluster. Alternatively, if the pre-join phase has lasted for over MAX_WAIT_SECONDS_BEFORE_JOIN seconds, the master node will proceed with processing the join requests and forming the cluster, regardless of the time elapsed since the last join request.
    After the master node has started processing join requests, it will no longer introduce any more waiting and join requests will be processed as they arrive. The only exception to this is if the master state is reset, which may happen in some cases like split-brain healing.
  - MAX_WAIT_SECONDS_BEFORE_JOIN
```
public static final HazelcastProperty MAX_WAIT_SECONDS_BEFORE_JOIN
```
    The maximum time that a newly-appointed master node waits before forming a cluster. Once a cluster is being started, a newly-appointed master node may receive a flurry of join requests. If these requests were processed immediately, the master node would have the overhead of processing each join request individually and informing the existing cluster members of the membership changes. Instead, the master will wait for some time to "batch" the initial join requests. This parameter defines maximum time that the master node will wait since the first received join request (a pre-join window) before it starts processing the join requests and forming a cluster. This is an upper limit on the cluster’s pre-join phase duration. Alternatively, if WAIT_SECONDS_BEFORE_JOIN seconds have passed since the last join request, the master node will proceed with processing the join requests and forming the cluster, regardless of the time elapsed since the first join request.
    After the master node has started processing join requests, it will no longer introduce any more waiting and join requests will be processed as they arrive. The only exception to this is if the master state is reset, which may happen in some cases like split-brain healing.
  - MAX_JOIN_SECONDS
```
public static final HazelcastProperty MAX_JOIN_SECONDS

  - HEARTBEAT_INTERVAL_SECONDS
```
public static final HazelcastProperty HEARTBEAT_INTERVAL_SECONDS
```
    The interval at which member heartbeat messages are sent
  - MASTERSHIP_CLAIM_TIMEOUT_SECONDS
```
public static final HazelcastProperty MASTERSHIP_CLAIM_TIMEOUT_SECONDS
```
    The timeout which defines when master candidate gives up waiting for response to its mastership claim. After timeout happens, non-responding member will be removed from member list.
  - MAX_NO_HEARTBEAT_SECONDS
```
public static final HazelcastProperty MAX_NO_HEARTBEAT_SECONDS
```
    The timeout which defines when a cluster member is removed because it has not sent any heartbeats.
  - PARTIAL_MEMBER_DISCONNECTION_RESOLUTION_HEARTBEAT_COUNT
```
public static final HazelcastProperty PARTIAL_MEMBER_DISCONNECTION_RESOLUTION_HEARTBEAT_COUNT
```
    The master member, i.e, the first member in the cluster member list administrates the cluster and kicks unreachable members with the heartbeat mechanism. It means that a non-master member (i.e, any member other than the master) does not send heartbeats to the master for the "heartbeat timeout" duration, it is kicked from the cluster. However, there can be heartbeat problems between non-master members as well. Since the master member is the single authority to update the cluster member list, non-master members report their heartbeat problems to the master so that the master can update the cluster member list.
    When the master receives a heartbeat problem report from another member, it first waits for a number of heartbeat rounds to allow other members to report their problems if there is any. After that, it takes all reports received so far and checks if it can update the cluster member in a way that the minimum number of members will be kicked from the cluster and there won't be any heartbeat problem between the remaining members.
    If this configuration option is set to 0, this functionality is disabled. It is recommended to be set to at least 3 or 5 so that the master will wait long enough to collect heartbeat problem reports. Otherwise, the master member can make sub-optimal decisions.
  - PARTIAL_MEMBER_DISCONNECTION_RESOLUTION_ALGORITHM_TIMEOUT_SECONDS
```
public static final HazelcastProperty PARTIAL_MEMBER_DISCONNECTION_RESOLUTION_ALGORITHM_TIMEOUT_SECONDS
```
    The partial member disconnection resolution mechanism uses a graph algorithm that finds a max-clique in non-polynomial time. Since it could take a lot of time to find a max-clique in a large graph, i.e, in a large cluster with lots of random network disconnections, we use a timeout mechanism to stop execution of the algorithm.
  - HEARTBEAT_FAILURE_DETECTOR_TYPE
```
public static final HazelcastProperty HEARTBEAT_FAILURE_DETECTOR_TYPE
```
    Heartbeat failure detector type. Available options are:
    
    deadline: A deadline based failure detector uses an absolute timeout for missing/lost heartbeats. After timeout member is considered as dead/unavailable.
    
    phi-accrual: Implementation of 'The Phi Accrual Failure Detector' by Hayashibara et al. as defined in their paper. Phi Accrual Failure Detector is adaptive to network/environment conditions, that's why a lower MAX_NO_HEARTBEAT_SECONDS (for example 10 or 15 seconds) can be used to provide faster detection of unavailable members.
    
    Default failure detector is deadline.
  - MEMBER_LIST_PUBLISH_INTERVAL_SECONDS
```

  - CLUSTER_SHUTDOWN_TIMEOUT_SECONDS
```
public static final HazelcastProperty CLUSTER_SHUTDOWN_TIMEOUT_SECONDS
```
    Once a member initiates cluster shutdown, it will either wait for all members to leave the cluster before shutting itself down. This parameter defines a timeout after which there may still be some members in the cluster but the initiator will give up and shut itself down regardless.

  - PARTITION_MAX_PARALLEL_MIGRATIONS
```
public static final HazelcastProperty PARTITION_MAX_PARALLEL_MIGRATIONS
```
    Maximum number of partition migrations to be executed concurrently on a member. Member can be either source or target of the migration.
    
    Having too much parallelization can increase the heap memory usage and overload the network during partition rebalance.
    
    Having less parallelization can increase the total migration completion time.
  - PARTITION_MAX_PARALLEL_REPLICATIONS
```
public static final HazelcastProperty PARTITION_MAX_PARALLEL_REPLICATIONS

```
    Time period to check if a client is still part of the cluster.
  - CLIENT_CLEANUP_TIMEOUT
```
public static final HazelcastProperty CLIENT_CLEANUP_TIMEOUT
```
    Timeout duration to decide if a client is still part of the cluster. If a member can not find any connection to a client in the cluster, it will clean up local resources that is owned by that client.
  - INIT_CLUSTER_VERSION
```
public static final HazelcastProperty INIT_CLUSTER_VERSION
```
    Override cluster version to use while node is not yet member of a cluster. The cluster version assumed before joining a cluster may affect the serialization format of cluster discovery & join operations and its compatibility with members of a cluster running on different Hazelcast codebase versions. The default is to use the node's codebase version. You may need to override it for your node to join a cluster running on a previous cluster version.
  - METRICS_ENABLED
```

```
    Enables/disables metrics collection altogether. This is a master switch for all metrics related functionality.
    NOTE: This property overrides BaseMetricsConfig.isEnabled().
    Using BaseMetricsConfig.setEnabled(boolean) and the declarative counterparts are preferred over using this property. The main purpose of making metrics collection configurable from properties too is allowing operators to configure the metrics subsystem from the outside during investigation without touching or copying the configuration potentially embedded into a signed artifact.

```
public static final HazelcastProperty JMX_UPDATE_INTERVAL_SECONDS
```
    Some JMX MBeans are cached (e.g. map, multimap, queue and replicated map) to reduce the overhead of calculating statistics. This parameter determines how much the MBeans can go stale, meaning after how much time elapses since the last calculated statistics should the MBean be refreshed.

```
    Enables or disables the SlowOperationDetector.
  - SLOW_OPERATION_DETECTOR_THRESHOLD_MILLIS
```
public static final HazelcastProperty SLOW_OPERATION_DETECTOR_THRESHOLD_MILLIS
```
    Defines a threshold above which a running operation in OperationService is considered to be slow. These operations will log a warning and will be shown in the Management Center with detailed information, e.g. stacktrace.
  - SLOW_OPERATION_DETECTOR_LOG_RETENTION_SECONDS
```
public static final HazelcastProperty SLOW_OPERATION_DETECTOR_LOG_RETENTION_SECONDS
```
    This value defines the retention time of invocations in slow operation logs.
    If an invocation is older than this value, it will be purged from the log to prevent unlimited memory usage. When all invocations are purged from a log, the log itself will be deleted.

```
public static final HazelcastProperty SLOW_OPERATION_DETECTOR_STACK_TRACE_LOGGING_ENABLED
```
    Defines if the stacktraces of slow operations are logged in the log file. Stacktraces will always be reported to the Management Center, but by default they are not printed to keep the log size small.
  - QUERY_PREDICATE_PARALLEL_EVALUATION
```
public static final HazelcastProperty QUERY_PREDICATE_PARALLEL_EVALUATION
```
    Run Query Evaluations for multiple partitions in parallel.
    Each Hazelcast member evaluates query predicates using a single thread by default. In most cases the overhead of inter-thread communication overweight benefit of parallel execution.
    When you have a large dataset and/or slow predicate you may benefit from parallel predicate evaluations. Set to true if you are using slow predicates or have < 100,000s entries per member.
    The default is false.
  - AGGREGATION_ACCUMULATION_PARALLEL_EVALUATION
```
public static final HazelcastProperty AGGREGATION_ACCUMULATION_PARALLEL_EVALUATION
```
    Run aggregation accumulation for multiple entries in parallel.
    Each Hazelcast member executes the accumulation stage of an aggregation using a single thread by default. In most cases it pays off to do it in parallel.
    The default is true.
  - GLOBAL_HD_INDEX_ENABLED
```
public static final HazelcastProperty GLOBAL_HD_INDEX_ENABLED
```
    Enables use of the concurrent HD index introduced in 4.1 for the IMDG predicate API (old query engine) and reverts to using the per-partition indexes. You may disable this property in case you encounter any regressions when using the query API and when upgrading to 4.1.
    The newly introduced SQL engine (see SqlService) will still use the concurrent HD index since it cannot use the partitioned indexes.
    
    Since:
    
    4.1
  - QUERY_RESULT_SIZE_LIMIT
```
public static final HazelcastProperty QUERY_RESULT_SIZE_LIMIT
```
    Result size limit for query operations on maps.
    This value defines the maximum number of returned elements for a single query result. If a query exceeds this number of elements, a QueryResultSizeExceededException will be thrown.
    This feature prevents an OOME if a single node is requesting the whole data set of the cluster, such as by executing a query with Predicates.alwaysTrue() predicate. This applies internally for the IMap.values(), IMap.keySet() and IMap.entrySet() methods, which are good candidates for OOME in large clusters.
    This feature depends on an equal distribution of the data on the cluster nodes to calculate the result size limit per node. Therefore, there is a minimum value of 100000 defined in QueryResultSizeLimiter. Configured values below the minimum will be increased to the minimum.
    The feature can be disabled by setting its value to -1 (which is the default value).
  - QUERY_MAX_LOCAL_PARTITION_LIMIT_FOR_PRE_CHECK
```
public static final HazelcastProperty QUERY_MAX_LOCAL_PARTITION_LIMIT_FOR_PRE_CHECK
```
    Maximum value of local partitions to trigger local pre-check for Predicates.alwaysTrue() predicate query operations on maps.
    To limit the result size of a query (QUERY_RESULT_SIZE_LIMIT); a local pre-check on the requesting node can be done before the query is sent to the cluster. Since this may increase the latency, the pre-check is limited to a maximum number of local partitions.
    By increasing this parameter, you can prevent the execution of the query on the cluster. Increasing this parameter increases the latency due to the prolonged local pre-check.
    The pre-check can be disabled by setting the value to -1.
    
    See Also:
    
    QUERY_RESULT_SIZE_LIMIT
  - QUERY_OPTIMIZER_TYPE
```
public static final HazelcastProperty QUERY_OPTIMIZER_TYPE

    RULES - for optimizations based on static rules
    
    NONE - optimization are disabled
    
    Values are case sensitive
  - INDEX_COPY_BEHAVIOR
```
public static final HazelcastProperty INDEX_COPY_BEHAVIOR
```
    Type of Query Index result copying behavior. Defines the behavior for index copying on index read/write. Supported in BINARY and OBJECT in-memory-formats. Ignored in NATIVE in-memory-format. Why is it needed? In order to support correctness the internal data-structures used by indexes need to do some copying. The copying may take place on-read or on-write:
    -> Copying on-read means that each index-read operation will copy the result of the query before returning it to the caller.This copying may be expensive, depending on the size of the result, since the result is stored in a map, which means that all entries need to have the hash calculated before being stored in a bucket. Each index-write operation however will be fast, since there will be no copying taking place.
    -> Copying on-write means that each index-write operation will completely copy the underlying map to provide the copy-on-write semantics. Depending on the index size, it may be a very expensive operation. Each index-read operation will be very fast, however, since it may just access the map and return it to the caller.
    -> Never copying is tricky. It means that the internal data structures of the index are concurrently modified without copy-on-write semantics. Index reads never copy the results of a query to a separate map. It means that the results backed by the underlying index-map can change after the query has been executed. Specifically an entry might have been added / removed from an index, or it might have been remapped. Should be used in cases when a the caller expects "mostly correct" results - specifically, if it's ok if some entries returned in the result set do not match the initial query criteria. The fastest solution for read and writes, since no copying takes place.
    It's a tuneable trade-off - the user may decide.
    Valid Values:
    
    COPY_ON_READY - Internal data structures of the index are concurrently modified without copy-on-write semantics. Index queries copy the results of a query on index read to detach the result from the source map. Should be used in index-write intensive cases, since the reads will slow down due to the copying. Default value.
    
    COPY_ON_WRITE - Internal data structures of the index are modified with copy-on-write semantics. Previously returned index query results reflect the state of the index at the time of the query and are not affected by future index modifications. Should be used in index-read intensive cases, since the writes will slow down due to the copying.
    
    NEVER - Internal data structures of the index are concurrently modified without copy-on-write semantics. Index reads never copy the results of a query to a separate map. It means that the results backed by the underlying index-map can change after the query has been executed. Specifically an entry might have been added / removed from an index, or it might have been remapped. Should be used in cases when a the caller expects "mostly correct" results - specifically, if it's ok if some entries returned in the result set do not match the initial query criteria. The fastest solution for read and writes, since no copying takes place.
  - CLIENT_ENGINE_QUERY_THREAD_COUNT
```
public static final HazelcastProperty CLIENT_ENGINE_QUERY_THREAD_COUNT
```
    The number of threads that the client engine has available for processing requests that are related to the query engine. When not set it is set as core-size.
  - WAN_CONSUMER_INVOCATION_THRESHOLD
```
public static final HazelcastProperty WAN_CONSUMER_INVOCATION_THRESHOLD
```
    Defines the pending invocation threshold for the Enterprise WAN replication implementation. Exceeding this threshold on a WAN consumer member makes the member delaying the WAN acknowledgment, thus slowing down the WAN publishers on the source side that send WAN events to the given WAN consumer. Setting this value to negative turns off the acknowledgement delaying feature.

```
public static final HazelcastProperty WAN_CONSUMER_ACK_DELAY_BACKOFF_INIT_MS

    The maximum size of the key batch sent to the partition owners for value loading and the maximum size of a key batch for which values are loaded in a single partition.
  - MAP_REPLICA_SCHEDULED_TASK_DELAY_SECONDS
```
public static final HazelcastProperty MAP_REPLICA_SCHEDULED_TASK_DELAY_SECONDS
```
    Scheduler delay for map tasks those are executed on backup members.
  - MAP_EXPIRY_DELAY_SECONDS
```
public static final HazelcastProperty MAP_EXPIRY_DELAY_SECONDS
```
    You can use MAP_EXPIRY_DELAY_SECONDS to deal with some possible edge cases, such as using EntryProcessor. Without this delay, you may see that an EntryProcessor running on the owner partition found a key, but entry backup processor did not find it on backup, and as a result when backup promotes to owner you will end up with an unprocessed key.
  - MAP_EVICTION_BATCH_SIZE
```
public static final HazelcastProperty MAP_EVICTION_BATCH_SIZE
```
    Maximum number of IMap entries Hazelcast will evict during a single eviction cycle. Eviction cycle is triggered by a map mutation. Typically it's OK to evict at most a single entry. However imagine the scenario where you are inserting values in a loop and in each iteration you double entry size. In this situation Hazelcast has to evict more than just a single entry - as all existing entries are smaller than the entry which is about to be added and removing any old entry cannot make sufficient room for the new entry.
    Default: 1
  - MAP_INVALIDATION_MESSAGE_BATCH_ENABLED
```
public static final HazelcastProperty MAP_INVALIDATION_MESSAGE_BATCH_ENABLED
```
    Defines Near Cache invalidation event batch sending is enabled or not.
  - MAP_INVALIDATION_MESSAGE_BATCH_SIZE
```
public static final HazelcastProperty MAP_INVALIDATION_MESSAGE_BATCH_SIZE
```
    Defines the maximum number of Near Cache invalidation events to be drained and sent to the event Near Cache in a batch.
  - MAP_INVALIDATION_MESSAGE_BATCH_FREQUENCY_SECONDS
```
public static final HazelcastProperty MAP_INVALIDATION_MESSAGE_BATCH_FREQUENCY_SECONDS
```
    Defines the Near Cache invalidation event batch sending frequency in seconds.
    When the number of events do not come up to MAP_INVALIDATION_MESSAGE_BATCH_SIZE in the given time period (which is defined by this property); those events are gathered into a batch and sent to target.
  - MAP_WRITE_BEHIND_QUEUE_CAPACITY
```
public static final HazelcastProperty MAP_WRITE_BEHIND_QUEUE_CAPACITY
```
    Setting this capacity is valid if you set writeCoalescing to false (see MapStoreConfig.setWriteCoalescing(boolean)). Otherwise its value will not be taken into account.
    The per node maximum write-behind queue capacity is the total of all write-behind queue sizes in a node, including backups.
    The maximum value which can be set is Integer.MAX_VALUE
  - OPERATION_CALL_TIMEOUT_MILLIS
```
public static final HazelcastProperty OPERATION_CALL_TIMEOUT_MILLIS
```
    Timeout to wait for a response when a remote call is sent, in milliseconds.
  - OPERATION_BACKUP_TIMEOUT_MILLIS
```
public static final HazelcastProperty OPERATION_BACKUP_TIMEOUT_MILLIS
```
    If an operation has backups, this property specifies how long the invocation will wait for acks from the backup replicas. If acks are not received from some backups, there will not be any rollback on other successful replicas.
  - FAIL_ON_INDETERMINATE_OPERATION_STATE
```
public static final HazelcastProperty FAIL_ON_INDETERMINATE_OPERATION_STATE
```
    When this configuration is enabled, if an operation has sync backups and acks are not received from backup replicas in time, or the member which owns primary replica of the target partition leaves the cluster, then the invocation fails with IndeterminateOperationStateException. However, even if the invocation fails, there will not be any rollback on other successful replicas.
  - INVOCATION_MAX_RETRY_COUNT
```
public static final HazelcastProperty INVOCATION_MAX_RETRY_COUNT
```
    Maximum number of retries for an invocation. After threshold is reached, invocation is assumed as failed.
  - INVOCATION_RETRY_PAUSE
```
public static final HazelcastProperty INVOCATION_RETRY_PAUSE
```
    Pause time between each retry cycle of an invocation in milliseconds.
  - BACKPRESSURE_ENABLED
```
public static final HazelcastProperty BACKPRESSURE_ENABLED
```
    Using back pressure, you can prevent an overload of pending asynchronous backups. With a map with a single asynchronous backup, producing asynchronous backups could happen at a higher rate than the consumption of the backup. This can eventually lead to an OOME (especially if the backups are slow).
    With back-pressure enabled, this can't happen.
    Back pressure is implemented by making asynchronous backups operations synchronous. This prevents the internal queues from overflowing because the invoker will wait for the primary and for the backups to complete. The frequency of this is determined by the sync-window.
    To deal with overloads of backups, the property OPERATION_BACKUP_TIMEOUT_MILLIS should be set to a larger value; above 60000 is recommended. Otherwise it can still happen backups accumulate.
  - BACKPRESSURE_SYNCWINDOW
```
public static final HazelcastProperty BACKPRESSURE_SYNCWINDOW
```
    Controls the frequency of a BackupAwareOperation getting its async backups converted to a sync backups. This is needed to prevent an accumulation of asynchronous backups and eventually running into stability issues.
    A sync window of 10 means that 1 in 10 BackupAwareOperations get their async backups convert to sync backups.
    A sync window of 1 means that every BackupAwareOperation get their async backups converted to sync backups. 1 is also the smallest legal value for the sync window.
    There is some randomization going on to prevent resonance. Therefore, with a sync window of n, not every Nth BackupAwareOperation operation gets its async backups converted to sync.
    This property only has meaning when backpressure is enabled.
  - BACKPRESSURE_BACKOFF_TIMEOUT_MILLIS
```
public static final HazelcastProperty BACKPRESSURE_BACKOFF_TIMEOUT_MILLIS
```
    Control the maximum timeout in millis to wait for an invocation space to be available.
    If an invocation can't be made because there are too many pending invocations, then an exponential backoff is done to give the system time to deal with the backlog of invocations. This property controls how long an invocation is allowed to wait before getting a HazelcastOverloadException.
    The value needs to be equal or larger than 0.
  - BACKPRESSURE_MAX_CONCURRENT_INVOCATIONS_PER_PARTITION
```
public static final HazelcastProperty BACKPRESSURE_MAX_CONCURRENT_INVOCATIONS_PER_PARTITION
```
    The maximum number of concurrent invocations per partition.
    To prevent the system from overloading, HZ can apply a constraint on the number of concurrent invocations. If the maximum number of concurrent invocations has been exceeded and a new invocation comes in, then an exponential back-off is applied till eventually a timeout happens or there is room for the invocation.
    By default it is configured as 100. With 271 partitions, that would give (271 + 1) * 100 = 27200 concurrent invocations from a single member. The +1 is for generic operations. The reasons why 100 is chosen are: - there can be concurrent operations that touch a lot of partitions which consume more than 1 invocation, and - certain methods like those from the IExecutor are also invocations and they can be very long running.
    No promise is made for the invocations being tracked per partition, or if there is a general pool of invocations.
  - DISABLE_STALE_READ_ON_PARTITION_MIGRATION
```
public static final HazelcastProperty DISABLE_STALE_READ_ON_PARTITION_MIGRATION
```
    Hazelcast allows read operations to be performed while a partition is being migrated. This can lead to stale reads for some scenarios. You can disable stale read operations by setting this system property’s value to "true". Its default value is "false", meaning that stale reads are allowed.
  - PARTITION_OPERATION_THREAD_COUNT
```
public static final HazelcastProperty PARTITION_OPERATION_THREAD_COUNT
```
    The number of partition operation handler threads per member.
    If this is less than the number of partitions on a member, partition operations will queue behind other operations of different partitions.
  - GENERIC_OPERATION_THREAD_COUNT
```
public static final HazelcastProperty GENERIC_OPERATION_THREAD_COUNT
```
    The number of generic operation handler threads per member.
    The default is max(2, processors/2);
  - PRIORITY_GENERIC_OPERATION_THREAD_COUNT
```
public static final HazelcastProperty PRIORITY_GENERIC_OPERATION_THREAD_COUNT
```
    The number of priority generic operation handler threads per member.
    The default is 1.
    Having at least 1 priority generic operation thread helps to improve cluster stability since a lot of cluster operations are generic priority operations and they should get executed as soon as possible. If there is a dedicated generic operation thread then these operations don't get delayed because the generic threads are busy executing regular user operations. So unless memory consumption is an issue, make sure there is at least 1 thread.
  - RESPONSE_THREAD_COUNT
```
public static final HazelcastProperty RESPONSE_THREAD_COUNT
```
    The number of threads that process responses.
    By default there are 2 response threads; this gives stable and good performance.
    If set to 0, the response threads are bypassed and the response handling is done on the IO threads. Under certain conditions this can give a higher throughput, but setting it to 0 should be regarded an experimental feature.
  - CACHE_INVALIDATION_MESSAGE_BATCH_ENABLED
```
public static final HazelcastProperty CACHE_INVALIDATION_MESSAGE_BATCH_ENABLED
```
    Defines cache invalidation event batch sending is enabled or not.
  - CACHE_INVALIDATION_MESSAGE_BATCH_SIZE
```
public static final HazelcastProperty CACHE_INVALIDATION_MESSAGE_BATCH_SIZE
```
    Defines the maximum number of cache invalidation events to be drained and sent to the event listeners in a batch.
  - CACHE_INVALIDATION_MESSAGE_BATCH_FREQUENCY_SECONDS
```
public static final HazelcastProperty CACHE_INVALIDATION_MESSAGE_BATCH_FREQUENCY_SECONDS
```
    Defines the cache invalidation event batch sending frequency in seconds.
    When the number of events do not come up to CACHE_INVALIDATION_MESSAGE_BATCH_SIZE in the given time period (which is defined by this property); those events are gathered into a batch and sent to target.
  - JCACHE_PROVIDER_TYPE
```
public static final HazelcastProperty JCACHE_PROVIDER_TYPE
```
    Forces the JCache provider, which can have values client or server, to force the provider type. If not provided, the provider will be client or server, whichever is found on the classpath first respectively.
  - CLIENT_ENGINE_THREAD_COUNT
```
public static final HazelcastProperty CLIENT_ENGINE_THREAD_COUNT
```
    The number of threads that the client engine has available for processing requests that are not partition specific. Most of the requests, such as map.put and map.get, are partition specific and will use a partition-specific operation thread, but there are also requests that can't be executed on a partition-specific operation thread, such as multimap.containsValue(value), because they need to access all partitions on a given member.
    When not set it is set as core-size.
  - CLIENT_ENGINE_BLOCKING_THREAD_COUNT
```
public static final HazelcastProperty CLIENT_ENGINE_BLOCKING_THREAD_COUNT
```
    The number of threads that the client engine has available for processing requests that are blocking (example: related to transactions) When not set it is set as core-size * 20.
  - EVENT_THREAD_COUNT
```
public static final HazelcastProperty EVENT_THREAD_COUNT
```
    Number of threads for the EventServiceImpl executor. The executor is responsible for executing the events. If you process a lot of events and have many cores, setting a higher value is a good practice. This way, more events can be processed in parallel.
  - EVENT_QUEUE_CAPACITY
```
public static final HazelcastProperty EVENT_QUEUE_CAPACITY
```
    The capacity of the EventServiceImpl executor. The executor is responsible for executing the events. If the events are produced at a higher rate than they are consumed, the queue grows in size. This can lead to an OutOfMemoryError if the accumulated events are not small enough to fit in memory. This capacity is shared between event topics. When the maximum capacity is reached, the items are dropped. This means that the event system is a 'best effort' system and there is no guarantee that you are going to get an event. Since the capacity is shared between topics, one topic might fill the entire queue and cause other topics to drop their messages.
  - EVENT_QUEUE_TIMEOUT_MILLIS
```
public static final HazelcastProperty EVENT_QUEUE_TIMEOUT_MILLIS
```
    The timeout for offering an event to the event executor for processing. If the event queue is full, the event might not be accepted to the queue and it will be dropped. This applies only to processing of local events. Remote events (events on a remote subscriber) have no timeout, meaning that the event can be rejected immediately.
  - EVENT_SYNC_TIMEOUT_MILLIS
```
public static final HazelcastProperty EVENT_SYNC_TIMEOUT_MILLIS
```
    To prevent overloading of the outbound connections, once in a while an event is made synchronous by wrapping it in a fake operation and waiting for a fake response. This causes the outbound write queue of the connection to get drained.
    This timeout configures the maximum amount of waiting time for this fake response. Setting it to a too low value can lead to an uncontrolled growth of the outbound write queue of the connection.
  - PHONE_HOME_ENABLED
```
public static final HazelcastProperty PHONE_HOME_ENABLED
```
    Enable or disable the sending of phone home data to Hazelcast’s phone home server.
  - SHUTDOWNHOOK_ENABLED
```
public static final HazelcastProperty SHUTDOWNHOOK_ENABLED
```
    Enable Hazelcast shutdownhook thread. When this is enabled, this thread terminates the Hazelcast instance without waiting to shutdown gracefully.
  - SHUTDOWNHOOK_POLICY
```
public static final HazelcastProperty SHUTDOWNHOOK_POLICY
```
    Behaviour when JVM is about to exit while Hazelcast instance is still running.
    Possible values: TERMINATE: Terminate Hazelcast immediately GRACEFUL: Initiate graceful shutdown. This can significantly slow-down JVM exit process, but it's tries to retain data safety.
    Default: TERMINATE
    You should always shutdown Hazelcast explicitly via HazelcastInstance.shutdown() It's not recommended to rely on shutdown hook, this is a last-effort measure.
  - LOGGING_TYPE
```
public static final HazelcastProperty LOGGING_TYPE
```
    Name of logging framework type to send logging events.
  - LOGGING_ENABLE_DETAILS
```
public static final HazelcastProperty LOGGING_ENABLE_DETAILS
```
    Controls whether cluster name, ip and version should be included in all log messages.
  - LOCK_MAX_LEASE_TIME_SECONDS
```
public static final HazelcastProperty LOCK_MAX_LEASE_TIME_SECONDS
```
    All locks which are acquired without an explicit lease time use this value (in seconds) as the lease time. When you want to set an explicit lease time for your locks, you cannot set it to a longer time than this value.
  - ENTERPRISE_LICENSE_KEY
```
public static final HazelcastProperty ENTERPRISE_LICENSE_KEY
```
    Hazelcast IMDG Enterprise license key.
  - SERIALIZATION_VERSION
```
public static final HazelcastProperty SERIALIZATION_VERSION
```
    Hazelcast serialization version. This is single byte value between 1 and Max supported serialization version.
    
    See Also:
    
    BuildInfo.getSerializationVersion()
  - SEARCH_DYNAMIC_CONFIG_FIRST
```
public static final HazelcastProperty SEARCH_DYNAMIC_CONFIG_FIRST
```
    By default, search for data structures config is performed within static configuration first:
    
    Exact match in static config
    
    Wildcard match in static config
    
    Exact match in dynamic config
    
    Wildcard match in dynamic config
    
    Fallback to default
    
    But sometimes it makes sense to perform search within dynamic configs first. If this property is set to true, search algorithm changes to:
    
    Exact match in dynamic config
    
    Wildcard match in dynamic config
    
    Exact match in static config
    
    Wildcard match in static config
    
    Fallback to default
  - MOBY_NAMING_ENABLED
```
public static final HazelcastProperty MOBY_NAMING_ENABLED
```
    Defines whether Moby Names should be used for instance name generating when it is not provided by user.
    Moby Name is a short human-readable name consisting of randomly chosen adjective and the surname of a famous person.
    If set to true, Moby Name will be chosen, otherwise a name that is concatenation of static prefix, number and cluster name.
    By default is true.
  - JOB_SCAN_PERIOD
```
public static final HazelcastProperty JOB_SCAN_PERIOD

```
public static final HazelcastProperty JET_IDLE_COOPERATIVE_MIN_MICROSECONDS
```
    The minimum time in microseconds the cooperative worker threads will sleep if none of the tasklets made any progress. Lower values increase idle CPU usage but may result in decreased latency. Higher values will increase latency and very high values (>10000µs) will also limit the throughput.
    The default is value is 25µs.
    Note: the underlying LockSupport.parkNanos(long) call may actually sleep longer depending on the operating system (up to 15000µs on Windows). See the Hazelcast blog post about this subject for more details.

```
public static final HazelcastProperty WAN_REPLICATE_IMAP_EVICTIONS
```
    Defines whether WAN replication events should be fired when values are evicted from IMap objects.
    The default value is false.
    NOTE: The expected use-case for this property to be enabled is very specific, namely where an exact copy of a source is wanted on a target with no evictions enabled; however in this scenario, the target cluster would need to have evictions enabled if it were to become the active cluster - failing to do so could lead to Out Of Memory or data inconsistency issues. The reverse would also be necessary if returning back to the original cluster. Ensure you have a plan for handling these scenarios (such as using Management Centre to configure evictions manually) before enabling this property and changing between active clusters.
