["Alessandro Solimando (Jira)" <ji...@apache.org>]

Alessandro Solimando commented on CALCITE-6907:
-----------------------------------------------

[~wenzhuang.zwz] thanks for bringing up the topic, it seems interesting but from the look of it, I think it will require broader discussion in the ML and surely more details/discussion here before starting the implementation.

> 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.
