Field Summary

Fields
Modifier and Type	Field and Description
`static HazelcastProperty`	`BACKPRESSURE_BACKOFF_TIMEOUT_MILLIS` Control the maximum timeout in millis to wait for an invocation space to be available.
`static HazelcastProperty`	`COMPATIBILITY_3_6_SERVER_ENABLED` When this property is true, if the client can not know the server version it will assume that the server is version 3.6.x.
`static HazelcastProperty`	`DISCOVERY_SPI_ENABLED` Enables the Discovery SPI lookup over the old native implementations.
`static HazelcastProperty`	`DISCOVERY_SPI_PUBLIC_IP_ENABLED` Enables the Discovery Joiner to use public ips from DiscoveredNode.
`static HazelcastProperty`	`EVENT_QUEUE_CAPACITY` Capacity of the executor that handles the incoming event packets.
`static HazelcastProperty`	`EVENT_THREAD_COUNT` Number of the threads to handle the incoming event packets.
`static HazelcastProperty`	`HEARTBEAT_INTERVAL` Time interval between the heartbeats sent by the client to the nodes.
`static HazelcastProperty`	`HEARTBEAT_TIMEOUT` Client sends heartbeat messages to the members and this is the timeout for this sending operations.
`static HazelcastProperty`	`INVOCATION_RETRY_PAUSE_MILLIS` Pause time between each retry cycle of an invocation in milliseconds.
`static HazelcastProperty`	`INVOCATION_TIMEOUT_SECONDS` When an invocation gets an exception because : - Member throws an exception.
`static HazelcastProperty`	`IO_BALANCER_INTERVAL_SECONDS` The interval in seconds between `IOBalancer` executions.
`static HazelcastProperty`	`IO_INPUT_THREAD_COUNT` Controls the number of socket input threads.
`static HazelcastProperty`	`IO_OUTPUT_THREAD_COUNT` Controls the number of socket output threads.
`static HazelcastProperty`	`MAX_CONCURRENT_INVOCATIONS` The maximum number of concurrent invocations allowed.
`static HazelcastProperty`	`SHUFFLE_MEMBER_LIST` Client shuffles the given member list to prevent all clients to connect to the same node when this property is set to true.

  - SHUFFLE_MEMBER_LIST
```
public static final HazelcastProperty SHUFFLE_MEMBER_LIST
```
    Client shuffles the given member list to prevent all clients to connect to the same node when this property is set to true. When it is set to false, the client tries to connect to the nodes in the given order.
  - HEARTBEAT_TIMEOUT
```
public static final HazelcastProperty HEARTBEAT_TIMEOUT
```
    Client sends heartbeat messages to the members and this is the timeout for this sending operations. If there is not any message passing between the client and member within the given time via this property in milliseconds, the connection will be closed.
  - HEARTBEAT_INTERVAL
```
public static final HazelcastProperty HEARTBEAT_INTERVAL
```
    Time interval between the heartbeats sent by the client to the nodes.
  - EVENT_THREAD_COUNT
```
public static final HazelcastProperty EVENT_THREAD_COUNT
```
    Number of the threads to handle the incoming event packets.
  - EVENT_QUEUE_CAPACITY
```
public static final HazelcastProperty EVENT_QUEUE_CAPACITY
```
    Capacity of the executor that handles the incoming event packets.
  - INVOCATION_TIMEOUT_SECONDS
```
public static final HazelcastProperty INVOCATION_TIMEOUT_SECONDS
```
    When an invocation gets an exception because : - Member throws an exception. - Connection between the client and member is closed. - Client's heartbeat requests are timed out. Time passed since invocation started is compared with this property. If the time is already passed, then the exception is delegated to the user. If not, the invocation is retried. Note that, if invocation gets no exception and it is a long running one, then it will not get any exception, no matter how small this timeout is set.
  - INVOCATION_RETRY_PAUSE_MILLIS
```
public static final HazelcastProperty INVOCATION_RETRY_PAUSE_MILLIS
```
    Pause time between each retry cycle of an invocation in milliseconds.
  - MAX_CONCURRENT_INVOCATIONS
```
public static final HazelcastProperty MAX_CONCURRENT_INVOCATIONS
```
    The maximum number of concurrent invocations allowed.
    To prevent the system from overloading, user 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 hazelcast will throw HazelcastOverloadException
    By default it is configured as Integer.MaxValue.
  - 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.
    
    When set to -1 then HazelcastOverloadException is thrown immediately without any waiting.
  - DISCOVERY_SPI_ENABLED
```
public static final HazelcastProperty DISCOVERY_SPI_ENABLED
```
    Enables the Discovery SPI lookup over the old native implementations. This property is temporary and will eventually be removed when the experimental marker is removed.
    
    Discovery SPI is disabled by default
  - DISCOVERY_SPI_PUBLIC_IP_ENABLED
```
public static final HazelcastProperty DISCOVERY_SPI_PUBLIC_IP_ENABLED
```
    Enables the Discovery Joiner to use public ips from DiscoveredNode. This property is temporary and will eventually be removed when the experimental marker is removed.
    
    Discovery SPI is disabled by default
  - COMPATIBILITY_3_6_SERVER_ENABLED
```
public static final HazelcastProperty COMPATIBILITY_3_6_SERVER_ENABLED
```
    When this property is true, if the client can not know the server version it will assume that the server is version 3.6.x. This property is especially needed if you are using ICache (or JCache).
  - IO_INPUT_THREAD_COUNT
```
public static final HazelcastProperty IO_INPUT_THREAD_COUNT
```
    Controls the number of socket input threads. Defaults to -1, so the system will determine. If SSL is disabled, system will default to 1. If SSL is enabled, system will default to 3.
  - IO_OUTPUT_THREAD_COUNT
```
public static final HazelcastProperty IO_OUTPUT_THREAD_COUNT
```
    Controls the number of socket output threads. Defaults to -1, so the system will determine. If SSL is disabled, system will default to 1. If SSL is enabled, system will default to 3.
  - IO_BALANCER_INTERVAL_SECONDS
```
public static final HazelcastProperty IO_BALANCER_INTERVAL_SECONDS
```
    The interval in seconds between IOBalancer executions. The shorter intervals will catch I/O Imbalance faster, but they will cause higher overhead.
    Please see the documentation of IOBalancer for a detailed explanation of the problem.
    The default is 20 seconds. A value smaller than 1 disables the balancer.
