This is a Beam issue indeed, though it is an issue with the FlinkRunner. So I think I will BCC the Flink list.
You may be in one of the following situations: - These timers should not be viewed as distinct by the runner, but deduped, per https://issues.apache.org/jira/browse/BEAM-8212#comment-16946013 - There is a different problem if you have an unbounded key space with windows that never expire, since then there are unbounded numbers of truly distinct (but irrelevant) timers. That is also the responsibility of the runner to simply not set timers that can never fire.
