[jira] [Work logged] (BEAM-9580) Nexmark Query 12 in streaming mode

Work Description: mxm commented on pull request #11346: [BEAM-9580] Allow Flink 1.10 processing timers to finish on pipeline shutdown
URL: https://github.com/apache/beam/pull/11346
Due to the new mailbox operator architecture in Flink 1.10, processing remaining
timers during operator shutdown can't be achieved by releasing the checkpoint
lock anymore. Timers are only drained after the close() method completes.
However, at this point new timers also cannot be set anymore.
This doesn't play well with some of Beam's code (e.g. SDF) which assumes that
timers can set new timers which are guaranteed to fire at the end of the
pipeline. With the current processing model of Flink 1.10 this cannot be
guaranteed. This has manifesting in the Nexmark and ValidatesRunner tests.
While I have considered other possibilities, this was the only way to restore
the timer behavior we support with Beam and have been implementing with the
previous versions of the Flink Runner.
