Keshav created BEAM-10458:
-----------------------------
Summary: Message limit for grpc message is set to default 4 MB
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
Assignee: Keshav
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.
