Summary: Optimize HepPlanner latency for large plan
Key: CALCITE-6907
URL: https://issues.apache.org/jira/browse/CALCITE-6907
Project: Calcite
Issue Type: Improvement
Reporter: Wenzhuang Zhu
HepPlanner cannot quickly optimize plan with 10K+ rel nodes.
We can improve it by:
1.HepPlanner support graph reuse for different HepProgram.
2.Don't do eager graph gc, e.g. for listener and graph iterator.
3.Use large plan friendly graph iterator.
