--------------------------------------
Summary: Remove desc in AbstractRelNode
Key: CALCITE-3458
URL: https://issues.apache.org/jira/browse/CALCITE-3458
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Haisheng Yuan
If the query is super large, e.g. contains tens of thousands of nodes or
expressions, the RelNode digest and desc become very large. The content of desc
and digest are almost the same, except that desc consists of id plus digest,
which causes OOM in our production system. So remove desc, just use {{id +
digest}} to produce description.
