Jark Wu created FLINK-32444: ------------------------------- Summary: Enable object reuse for Flink SQL jobs by default Key: FLINK-32444 URL: https://issues.apache.org/jira/browse/FLINK-32444 Project: Flink Issue Type: New Feature Components: Table SQL / API Reporter: Jark Wu Fix For: 1.18.0
Currently, object reuse is not enabled by default for Flink Streaming Jobs, but is enabled by default for Flink Batch jobs. That is not consistent for stream-batch unification. Besides, SQL operators are safe to enable object reuse and this is a great performance improvement for SQL jobs. We should also be careful with the Table-DataStream conversion case (StreamTableEnvironment) which is not safe to enable object reuse by default. Maybe we can just enable it for SQL Client/Gateway and TableEnvironment. -- This message was sent by Atlassian Jira (v8.20.10#820010)
