Weiqing Yang created FLINK-38242: ------------------------------------ Summary: Improve upgrading documentation for SQL/Table API state compatibility and add Flink 2.x to compatibility table Key: FLINK-38242 URL: https://issues.apache.org/jira/browse/FLINK-38242 Project: Flink Issue Type: Improvement Components: Documentation Reporter: Weiqing Yang
This ticket aims to improve the current upgrading documentation in two areas: 1. **SQL/Table API State Compatibility Warning**: The current compatibility guidelines do not clearly warn that SQL/Table API jobs can encounter state incompatibilities during minor version upgrades (e.g., 1.16 → 1.20) due to changes in query optimizers and operator topologies, giving the impression that the rules apply uniformly to all job types. 2. **Missing Flink 2.x Versions**: The compatibility table is missing Flink 2.0.x and 2.1.x versions. Changes needed: - Add clear warning about SQL/Table API state compatibility in the Compatibility Table section - Add Flink 2.0.x and 2.1.x rows to the compatibility table -- This message was sent by Atlassian Jira (v8.20.10#820010)
