[GitHub] [beam] mosche commented on issue #21378: Canceling a timer by ID is not yet supported in InMemoryTimerInternals

Same issue apparently exists for the Flink runner.
From user@beam
> When running on Flink, eventually it hits an unsupported exception "Canceling a timer by ID is not yet supported." on this line [1]. The source inputs are AVRO files for testing (batch) but will use kafka topics (streaming) when deployed.
>
> This happens when the batch is filled (10 items) and the max buffering time timer needs to be cancelled.
>
> Anyone else observed this issue?
>
> On a related note. Looks like the FlinkStatefulDoFnFunction [2] uses InMemoryTimerInternals. Curious why is FlinkTimerInternals not used? I would guess there's a difference between batch and streaming requirements?
