yux created FLINK-35762: --------------------------- Summary: Cache hashCode for immutable map key classes Key: FLINK-35762 URL: https://issues.apache.org/jira/browse/FLINK-35762 Project: Flink Issue Type: Improvement Components: Flink CDC Reporter: yux
As suggested by [~kunni], hash code caching is a common optimization in Java world (for example, java.lang.String uses such optimization to reduce duplicate hash calculation since String as a hashmap key is quite common). Such optimization could be applied in CDC to optimize execution performance. -- This message was sent by Atlassian Jira (v8.20.10#820010)
