Field Detail

INC_DEC_REF_COUNT_PERIOD_MS

protected static final long INC_DEC_REF_COUNT_PERIOD_MS

How often to we notify the other side that an object is actually used (by invoking ObjectManager.incRefCount(Object, Uid) on the other side).

For performance reasons, we do not perform one increment-reference-RPC per object, but rather collect them here for a while and do one remote-procedure-call for all that occurred during this time period.

This period must be significantly shorter than the corresponding timeout ObjectManager.EVICT_ZERO_REFERENCE_OBJECT_REFS_TIMEOUT_MS!
