Work Description: tweise commented on issue #8351: [BEAM-7112] [flink]
Defer state cleanup till bundle completion
URL: https://github.com/apache/beam/pull/8351#issuecomment-485184090
The state keys need to be encoded as NESTED currently. My attempt to use the
ByteString directly caused the checkpoint failure. I reverted that and instead
also encode the state key of cleanup timer NESTED. We should look into
eliminating the redundant key encoding.

> Cleanup timers and user timers are fired at the watermark. Processing of
> timers in the SDK worker is asynchronous, so it is possible that the state is
> already removed when the user timer callback executes.
