Field Detail

synchronousOverflowCounter

public final AtomicLong synchronousOverflowCounter

#of synchronous overflows that have taken place. This counter is incremented each time the synchronous overflow operation is complete.

synchronousOverflowMillis

public final AtomicLong synchronousOverflowMillis

The elapsed milliseconds for synchronous overflow processing to date.

asynchronousOverflowStartMillis

public final AtomicLong asynchronousOverflowStartMillis

The time in milliseconds since the epoch at which the most recent asynchronous overflow started. This is used to compute the elapsed asynchronous overflow time when the service is currently performing asynchronous overflow processing. The value is set each time asynchronous overflow processing starts, but never cleared.

asynchronousOverflowCounter

public final AtomicLong asynchronousOverflowCounter

#of asynchronous overflows that have taken place. This counter is incremented each time the entire overflow operation is complete, including any asynchronous post-processing of the old journal.

asynchronousOverflowMillis

public final AtomicLong asynchronousOverflowMillis

The elapsed milliseconds for asynchronous overflow processing to date.

asynchronousOverflowFailedCounter

public final AtomicLong asynchronousOverflowFailedCounter

The #of asynchronous overflow operations which fail.

See Also:

AsynchronousOverflowTask

asynchronousOverflowTaskFailedCounter

public final AtomicLong asynchronousOverflowTaskFailedCounter

The #of asynchronous overflow tasks (index partition splits, joins, or moves) that failed.

asynchronousOverflowTaskCancelledCounter

public final AtomicLong asynchronousOverflowTaskCancelledCounter

The #of asynchronous overflow tasks (index partition splits, joins, or moves) that were canceled due to timeout.

OverflowManager.Options.OVERFLOW_TIMEOUT

indexPartitionBuildCounter

public final AtomicLong indexPartitionBuildCounter

#of successful index partition incremental build operations.

indexPartitionMergeCounter

public final AtomicLong indexPartitionMergeCounter

#of successful index partition compacting merge operations.

indexPartitionSplitCounter

public final AtomicLong indexPartitionSplitCounter

#of successful index partition split operations.

indexPartitionTailSplitCounter

public final AtomicLong indexPartitionTailSplitCounter

#of successful index partition tail split operations.

indexPartitionJoinCounter

public final AtomicLong indexPartitionJoinCounter

#of successful index partition join operations.

indexPartitionMoveCounter

public final AtomicLong indexPartitionMoveCounter

#of successful index partition move operations.

indexPartitionReceiveCounter

public final AtomicLong indexPartitionReceiveCounter

#of successful index partition move operations where this service was the target of the move (it received the index partition).
