> Fixes the performance issue mentioned in https://github.com/apache/spark/pull/32559/files#r633488455 and partially fixed in https://github.com/apache/spark/pull/33142/files#r660897248 using a new option to remove expressions from equivalence maps. Fixes an issue with identifying common expressions in conditional expressions (a side effect of the above). Fixes the issue of transparently canonicalized expressions (like PromotePrecision) are considered common subexpressions. Could you explain more about the three points listed in the description? -- This is an automated message from the Apache Git Service.
