Haisheng Yuan created CALCITE-4071: -------------------------------------- Summary: Make RelNode Immutable Key: CALCITE-4071 URL: https://issues.apache.org/jira/browse/CALCITE-4071 Project: Calcite Issue Type: Improvement Components: core Reporter: Haisheng Yuan
Currently, RelNode is mutable, mainly in planner. That makes planner code error-prone, hard to maintain, and complicate the logic. Let's try to avoid using {{replaceInput}}, at least inside planner, and see if we can deprecate {{replaceInput}}. That will make planner more robust. -- This message was sent by Atlassian Jira (v8.3.4#803005)
