Jiatao Tao commented on CALCITE-4224:
-------------------------------------
`RelNode.getDigest` only output its own node's digest, not the tree string.
It's the same with RelOptUtil.toString(rel), but what can be more convenient
than we call rel.getTreeDigest directly, especially in a high-frequency call
like this.
> Add an method for RelNode to output its tree digest like RelOptUtil.toString
