/**
 * Processes all pending processing timers. This is intended for use during shutdown. From Flink
 * 1.10 on, processing timer execution is stopped when the operator is closed. This leads to
 * problems for applications which assume all pending timers will be completed. Although Flink
 * does drain the remaining timers after close(), this is not sufficient because no new timers
 * are allowed to be scheduled anymore. This breaks Beam pipelines which rely on all processing
 * timers to be scheduled and executed.
