Method Detail

beginBatch

void beginBatch()

Initializes internal state before works are submitted.

endBatch

CompletableFuture<?> endBatch()

Ensures all works submitted since the last call to beginBatch() will actually be executed, along with any finishing task (commit, ...).

Returns:

A future completing when the executor is allowed to start another batch.

completeOrDelay

long completeOrDelay()

Executes any outstanding operation if possible, or return an estimation of when they can be executed.

Called when the executor considers the work queue complete and does not plan on submitting another batch due to work starvation.

Returns:

0 if there is no outstanding operation, or a positive number of milliseconds if there are outstanding operations and completeOrDelay() must be called again that many milliseconds later.
