Kenneth Knowles updated BEAM-10305:
-----------------------------------
Status: Open (was: Triage Needed)
> InMemoryBagUserStateFactory creates a cache token per state cell
> ----------------------------------------------------------------
>
> Key: BEAM-10305
> URL: https://issues.apache.org/jira/browse/BEAM-10305
> Project: Beam
> Issue Type: Bug
> Components: java-fn-execution, runner-flink, sdk-py-harness
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: P3
>
> When the state cache is enabled in the Python SDK, the batch mode of the
> Flink Runner only allows a single state cell because a new cache token is
> generated for each state cell. The caching code in the Python SDK Harness
> only supports one global cache token per user state handler. Theoretically
> multiple cache tokens would work but would just be adding to the payload. We
> should make sure to just send a single cache token in batch mode (which is
> already the case in streaming).
