Element Details

• name

  String name

  Configures the required name of this GatewaySender. This name is also used as the name of the bean registered in the Spring Container as well as the name used in the resolution of GatewaySender properties from application.properties. For example, spring.data.gemfire.gateway.sender.<name>.manual-start that is specific to this GatewaySender.

• alertThreshold

  int alertThreshold

Alternatively use the spring.data.gemfire.gateway.sender.<name>.alert-threshold property in application.properties.

  Default:

  0

• batchConflationEnabled

  boolean batchConflationEnabled

  A boolean flag to indicate if the configured GatewaySenders should use conflate entries in each batch.

Alternatively use the spring.data.gemfire.gateway.sender.<name>.batch-conflation-enabled property in application.properties.

  Default:

  false

• batchSize

  int batchSize

  Configures the maximum batch size that the GatewaySender sends to the remote site. This property works in conjunction with the EnableGatewaySenders.batchTimeInterval() setting.

Alternatively use the spring.data.gemfire.gateway.sender.<name>.batch-size property in application.properties.

  Default:

  100

• batchTimeInterval

  int batchTimeInterval

  Configures the maximum batch time interval in milliseconds that the GatewaySender waits before attempting to send a batch of queued objects to the remote GatewayReceiver. This property works in conjunction with the EnableGatewaySenders.batchSize() setting. A GatewaySender will send when either the batch-size or batch-time-interval is reached. Defaults to 1000. Alternatively use the spring.data.gemfire.gateway.sender.<name>.batch-time-interval property in application.properties.

  Default:

  1000

• diskStoreReference

  String diskStoreReference

  Configures the DiskStore used by a GatewaySender} when persisting the GatewaySender queue's data. This setting should be set when the persistent() property is set to true. Defaults to "". Alternatively use the spring.data.gemfire.gateway.sender.<name>.diskstore-reference property in application.properties.

  Default:

  ""

• diskSynchronous

  boolean diskSynchronous

  A boolean flag to indicate if the configured GatewaySender should use synchronous DiskStore writes. Defaults to true. Alternatively use the spring.data.gemfire.gateway.sender.<name>.disk-synchronous property in application.properties.

  Default:

  true

• dispatcherThreads

  int dispatcherThreads

  Configures the number of dispatcher threads that the GatewaySender will try to use to dispatch the queued events. Defaults to 5. Alternatively use the spring.data.gemfire.gateway.sender.<name>.dispatcher-threads property in application.properties.

  Default:

  5

• eventFilters

  String[] eventFilters

  Configures the list of GatewayEventFilters to be applied to this GatewaySender. GatewayEventFilters are used to filter out objects from the sending queue before dispatching them to the remote GatewayReceiver. Defaults to empty list. Alternatively use the spring.data.gemfire.gateway.sender.<name>.event-filters property in application.properties.

  Default:

  {}

• eventSubstitutionFilter

  String eventSubstitutionFilter

  Configures the GatewayEventSubstitutionFilter used by this GatewaySender. The GatewayEventSubstitutionFilter is used to replace values on objects before they are enqueued for remote replication. Defaults to GatewaySenderConfiguration.DEFAULT_EVENT_SUBSTITUTION_FILTER. Alternatively use the spring.data.gemfire.gateway.sender.<name>.event-substitution-filter property in application.properties.

  Default:

  ""

• manualStart

  boolean manualStart

  A boolean flag indicating whether the configured GatewaySender should be started automatically.

  Defaults to {@value @EnableGatewaySenderConfiguration.DEFAULT_MANUAL_START}. Alternatively use the spring.data.gemfire.gateway.sender.<name>.manual-start property in application.properties.

  Default:

  false

• maximumQueueMemory

  int maximumQueueMemory

  Configures the maximum size in megabytes that the GatewaySender's queue may take in heap memory before overflowing to disk. Defaults to 100. Alternatively use the spring.data.gemfire.gateway.sender.<name>.maximum-queue-memory property in application.properties.

  Default:

  100

• orderPolicy

  OrderPolicyType orderPolicy

  Configures the ordering policy that this GatewaySender will use when queueing entries to be replicated to a remote GatewayReceiver.

  There are three different ordering policies:

  • OrderPolicyType.KEY - Order of events preserved on a per key basis
  • OrderPolicyType.THREAD - Order of events preserved by the thread that added the event
  • OrderPolicyType.PARTITION - Order of events is preserved in order that they arrived in partitioned Region

  Defaults to OrderPolicyType.KEY. Alternatively use the spring.data.gemfire.gateway.sender.<name>.order-policy property in application.properties.

  Default:

  KEY

• parallel

  boolean parallel

  A boolean} flag indicating whether the configured GatewaySender should use parallel replication. Parallel replication means that each CacheServer that defines a GatewaySender will send data to a remote GatewayReceiver. Defaults to false. Alternatively use the spring.data.gemfire.gateway.sender.<name>.parallel property in application.properties.

  Default:

  false

• persistent

  boolean persistent

  A boolean flag indicating whether the configured GatewaySender should use persistence. This setting should be used in conjunction with the disk-store-reference property. Defaults to false. Alternatively use the spring.data.gemfire.gateway.sender.<name>.persistent property in application.properties.

  Default:

  false

• regions

  String[] regions

  Configures the list of Region names that will be configured with this GatewaySender for replication. An empty list denotes that ALL Regions are to be replicated to the remote GatewayReceiver. Defaults to empty list. Alternatively use the spring.data.gemfire.gateway.sender.<name>.region-names property in application.properties.

  Default:

  {}

• remoteDistributedSystemId

  int remoteDistributedSystemId

  Configures the id of the remote distributed system (cluster) that this GatewaySender will send its data to. Defaults to {@value @EnableGatewaySenderConfiguration.DEFAULT_REMOTE_DISTRIBUTED_SYSTEM_ID}. Alternatively use the spring.data.gemfire.gateway.sender.<name>.remote-distributed-system-id property in application.properties.

  Default:

  -1

• socketBufferSize

  Default:

  524288

• socketReadTimeout

  int socketReadTimeout

  Configures the amount of time in milliseconds that this GatewaySender will wait to receive an acknowledgment from a remote site. By default this is set to 0, which means there is no timeout. The minimum allowed timeout is 30000 (milliseconds). Defaults to 0. Alternatively use the spring.data.gemfire.gateway.sender.<name>.socket-read-timeout property in application.properties.

  Default:

  0

• transportFilters

  String[] transportFilters

  Configures an in-order list of GatewayTransportFilter objects to be applied to this GatewaySender. Defaults to empty list. Alternatively use the spring.data.gemfire.gateway.sender.<name>.transport-filters property in application.properties.
