Timo Walther created FLINK-26075: ------------------------------------ Summary: Persist per-ExecNode configuration Key: FLINK-26075 URL: https://issues.apache.org/jira/browse/FLINK-26075 Project: Flink Issue Type: Sub-task Components: Table SQL / Planner Reporter: Timo Walther
Even though a compiled plan is static, some configuration options still change the topology of an ExecNode. In general, we will request users to keep the configuration constant between Flink versions. However, setting configuration more fine-grained per-ExecNode is a frequently requested feature. It can also allow us to set the parallelism more fine-grained in the future. We need the following infrastructure for the mentioned use cases: - Every ExecNode can have a configuration - By default the configuration per node are the values from the global configuration using the keys from the ExecNodeMetadata annotation. - If the persisted plan contains a configuration, the persisted configuration is merge with the global configuration and has priority. -- This message was sent by Atlassian Jira (v8.20.1#820001)
