Field Detail

iterationQueueCapacity

public int iterationQueueCapacity

If the iteration client needs more time then the read threads, the queue fills up. When the capacity is reached the reading threads block until the client is requesting the next entry.

A low number makes sense here just to make sure that the read threads are not waiting if the iterator client is doing some processing. We should never put a large number here, to keep overall memory capacity control within the cache and don't introduce additional buffers.

When the value is 0 a SynchronousQueue is used.

useManagerThreadPool

public boolean useManagerThreadPool

User global thread pool are a separate one. FIXME: Don't use global pool, there are some lingering bugs...

terminationInfoSeconds

public int terminationInfoSeconds

Thread termination writes a info log message, if we still wait for termination. Set to 0 to disable. Default: 5

terminationTimeoutSeconds

public int terminationTimeoutSeconds

Maximum time to await the termination of all executor threads. Default: 2000
