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). |

chunkSize()
The state will be transferred in batches of
chunkSize cache entries. |

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. |

This is the maximum amount of time - in milliseconds - to wait for state from neighboring

, 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.public long timeout()

If chunkSize is equal to Integer.MAX_VALUE, the state will be transferred in all at once. Not recommended.public boolean awaitInitialTransfer()
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.public AttributeSet attributes()
