### What happened? Spanner Change Streams reading query may early terminate and introduce data loss when dataflow worker has CPU utilization. This was caused by how timestamps were being tracked when queries completed. Specifically, an unbounded end timestamp is no longer permitted for the change stream query RPC. However, if a query reached its calculated artificial end timestamp, the code wasn't careful enough and could accidentally advance the restriction tracker to the full, potentially unbounded end timestamp of the original range. The issue was fixed by https://github.com/apache/beam/pull/37326 ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [x] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Prism Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
