The method performs flushing of any internal buffers that may hold log records.
The method may take considerable time to complete and may block both the calling thread and threads attempting to put new records into the sink while this call is in progress.

The method indicates that the sink passes log records between different threads.
This information is needed by the logging core to detach log records from all thread-specific resources before passing it to the sink.
