fetchInMemoryState
public boolean fetchInMemoryState()
Iftrue
, 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 thannumOwner
owners.

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()
The state will be transferred in batches ofchunkSize
cache entries. If chunkSize is equal to Integer.MAX_VALUE, the state will be transferred in all at once. Not recommended.
-
awaitInitialTransfer
public boolean awaitInitialTransfer()
Iftrue
, this will cause the first call to methodCacheManager.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 tofalse
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.
