--------------------------------------------
Summary: Improve performance of AbstractRelNode#computeDigest
Key: CALCITE-2902
URL: https://issues.apache.org/jira/browse/CALCITE-2902
Project: Calcite
Issue Type: Improvement
Affects Versions: 1.18.0
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
Fix For: 1.19.0
Compute digest is a method which is called very often in multiple places. More
frequently we end up here by calls through the VolcanoPlanner when we need to
register a relational expression which is another very common operation. The
profiler shows that we are spending quite some time in this method.
