[jira] [Commented] (BEAM-11210) ExecutableStageDoFnOperator should fire processing time timers properly instead of draining it directly when close() happens

["Maximilian Michels (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-11210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17229888#comment-17229888 ] 

Maximilian Michels commented on BEAM-11210:
-------------------------------------------

Processing timers have to be manually drained after the operator shuts down and {{close()}} is called. This does not happen if checkpointing is enabled or the \{{shutdownSourcesAfterIdleMs}} is used. Context: https://github.com/apache/beam/pull/13105#discussion_r521252916

> We hit this case when processing time timer holds the watermark but at the same time we are closing the operator.
> One typical case is when SDF sets timer for rescheduling residuals.
