Class StateTransferConfiguration

java.lang.Object
  extended by org.infinispan.configuration.cache.StateTransferConfiguration

public class StateTransferConfiguration
extends Object

Configures how state is retrieved when a new cache joins the cluster. Used with invalidation and replication clustered modes.

Since:
5.1

Method Summary
 boolean awaitInitialTransfer()
          If true, this will cause the first call to method CacheManager.getCache() on the joiner node to block and wait until the joining is complete and the cache has finished receiving state from neighboring caches (if fetchInMemoryState is enabled).
 int chunkSize()
          If > 0, the state will be transferred in batches of chunkSize cache entries.
 boolean equals(Object o)
           
 boolean fetchInMemoryState()
          If true, the cache will fetch data from the neighboring caches when it starts up, so the cache starts 'warm', although it will impact startup time.
 int hashCode()
           
protected  Boolean originalAwaitInitialTransfer()
          We want to remember if the user didn't configure awaitInitialTransfer for the default cache.
protected  Boolean originalFetchInMemoryState()

Method Detail

fetchInMemoryState

public boolean fetchInMemoryState()
If true, the cache will fetch data from the neighboring caches when it starts up, so the cache starts 'warm', although it will impact startup time.

In distributed mode, state is transferred between running caches as well, as the ownership of keys changes (e.g. because a cache left the cluster). Disabling this setting means a key will sometimes have less than numOwner owners.


originalFetchInMemoryState

protected Boolean originalFetchInMemoryState()
We want to remember if the user didn't configure fetchInMemoryState for the default cache.


timeout

public long timeout()
This is the maximum amount of time - in milliseconds - to wait for state from neighboring caches, before throwing an exception and aborting startup.


timeout

public StateTransferConfiguration timeout(long l)
This is the maximum amount of time - in milliseconds - to wait for state from neighboring caches, before throwing an exception and aborting startup.


chunkSize

public int chunkSize()
If > 0, the state will be transferred in batches of chunkSize cache entries. If <= 0, the state will be transferred in all at once. Not recommended.


awaitInitialTransfer

public boolean awaitInitialTransfer()
If true, this will cause the first call to method CacheManager.getCache() on the joiner node to block and wait until the joining is complete and the cache has finished receiving state from neighboring caches (if fetchInMemoryState is enabled). This option applies to distributed and replicated caches only and is enabled by default. Please note that setting this to false will make the cache object available immediately but any access to keys that should be available locally but are not yet transferred will actually cause a (transparent) remote access. While this will not have any impact on the logic of your application it might impact performance.


originalAwaitInitialTransfer

protected Boolean originalAwaitInitialTransfer()
We want to remember if the user didn't configure awaitInitialTransfer for the default cache.
