> Labels: pull-request-available
>
> FLINK-9423 added support for efficient timer deletions. This feature is
> available since Flink 1.6 and should be used by the relational operator of
> SQL and Table API.
> Currently, we use a few workarounds to handle situations when deleting timers
> would be the better solution.
