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? > > [1] [https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/core-java/src/main/java/org/apache/beam/runners/core/InMemoryTimerInternals.java#L157](https://urldefense.com/v3/__https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/core-java/src/main/java/org/apache/beam/runners/core/InMemoryTimerInternals.java*L157__;Iw!!CiXD_PY!Unl7jPgD471rWqXoU1CFDTX5qSwKpFHAGeryXtengpgyI2UDIfpkehBS3_SRwZFccFP97Hp__p4$) > [2] [https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/flink/src/main/java/org/apache/beam/runners/flink/translation/functions/FlinkStatefulDoFnFunction.java#L136](https://urldefense.com/v3/__https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/flink/src/main/java/org/apache/beam/runners/flink/translation/functions/FlinkStatefulDoFnFunction.java*L136__;Iw!!CiXD_PY!Unl7jPgD471rWqXoU1CFDTX5qSwKpFHAGeryXtengpgyI2UDIfpkehBS3_SRwZFccFP97zQLGAI$) > [3] [https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/flink/src/main/java/org/apache/beam/runners/flink/translation/wrappers/streaming/DoFnOperator.java#L1314](https://urldefense.com/v3/__https://github.com/apache/beam/blob/b87f1f01197a78d60fb08a0ee7a4ef96bc4e08eb/runners/flink/src/main/java/org/apache/beam/runners/flink/translation/wrappers/streaming/DoFnOperator.java*L1314__;Iw!!CiXD_PY!Unl7jPgD471rWqXoU1CFDTX5qSwKpFHAGeryXtengpgyI2UDIfpkehBS3_SRwZFccFP9bD4M2yo$) -- This is an automated message from the Apache Git Service.
