Field Detail

PROP_APPLICATION_VALIDATION_TOKEN

public static final String PROP_APPLICATION_VALIDATION_TOKEN

This property can be used to verify that Hazelcast nodes only join when their 'application' level configuration is the same. So imagine that you have multiple machines, but you want to make sure that each machine that is going to join the cluster has exactly the same 'application level' settings, so settings that are not part of the Hazelcast configuration, but maybe some filepath. To prevent these machines, with potential different application level configuration, to form a cluster, this property can be set. You could use actual values, e.g. string paths, but you can also use e.g. an md5 hash. We'll give the give the guarantee that only nodes are going to form a cluster where the token is an exact match. If this token is different, the member can't be started and therefor you will get the guarantee that all members in the cluster, will have exactly the same application validation token. This validation-token will be checked before member join the cluster.

PROP_PERFORMANCE_MONITORING_ENABLED

public static final String PROP_PERFORMANCE_MONITORING_ENABLED

The performance monitor is a tool useful to see all kinds of internal performance metrics. Currently it is quite limited since it will only show read/write events per selector and operations executed per operation-thread. But in the future all kinds of new metrics will be added. The performance monitor logs all metrics into the log file.

public static final String PROP_CLIENT_ENGINE_THREAD_COUNT

The number of threads the client engine has available for processing requests that are not partition specific. Most of the request e.g. map.put/map.get are partition specific and will use a partition-operation-thread, but there are also request that can't be executed on a partition-specific operation-thread, e.g. multimap.contain(value) because it needs to access all partitions on a given member.

PROP_BACKPRESSURE_ENABLED

public static final String PROP_BACKPRESSURE_ENABLED

Using back pressure one can prevent an overload of pending asynchronous backups. Imagine there is a map with a single asynchronous backup, it could happen that producing asynchronous backups happens at a higher rate than the consumption of the backup and this can eventually lead to an OOME (especially of the backups are slow). With back-pressure enabled this can't happen. It is implemented by making asynchronous backups operations synchronous. This prevent the internal queues to overflow because the invoker will wait for the primary and the backups to complete. The frequency of this is determined by the sync-window. In Hazelcast 3.4.1 we'll provide back pressure for any async operation; not only for sync operations with async backups. In the future we'll replace this approach by relying on TCP/IP congestion control; but for this to work we need to create multiple connections between members because currently a member can't stop consuming from a connection when that member is overloaded because it could also stop to read important packets like heartbeats and other system operations.

PROP_BACKPRESSURE_SYNCWINDOW

public static final String PROP_BACKPRESSURE_SYNCWINDOW

This property only has meaning when back-pressure is enabled. The larger the sync-window the less frequent a asynchronous backup is converted to a sync backup.
