> Key: BEAM-10458
> URL: https://issues.apache.org/jira/browse/BEAM-10458
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-harness
> Affects Versions: 2.22.0
> Reporter: Keshav
> Priority: P3
> Time Spent: 1h
> Remaining Estimate: 0h
>
> The default limit of a grpc message is set low to 4 MB, and is not overridden
> in the sdk_worker.py for the _control_channel. This was first discovered when
> submitting a beam job via a flink operator orchestrated by kubernetes
> ([https://github.com/GoogleCloudPlatform/flink-on-k8s-operator)|https://github.com/GoogleCloudPlatform/flink-on-k8s-operator].
> This issue was resolved for apache-beam==2.18 in BEAM-10334, but exists in
> apache-beam==2.22 (and presumably all versions 2.17 onwards).
>
> This can be fixed by modifying the options parameter to allow any size grpc
> message to be sent or received.
