Summary: Race condition in request id generation of GrpcStateRequestHandler Key: BEAM-8403 URL: https://issues.apache.org/jira/browse/BEAM-8403 Project: Beam Issue Type: Bug Components: sdk-py-harness Reporter: Maximilian Michels Assignee: Maximilian Michels Fix For: 2.17.0 There is a race condition in {{GrpcStateRequestHandler}} which surfaced after the recent changes to process append/clear state request asynchronously. The race condition can occur if multiple Runner workers process a transform with state requests with the same SDK Harness. For example, this setup occurs with Flink when a TaskManager has multiple task slots and two or more of those slots process the same stateful stage against an SDK Harness.
