Julian Hyde commented on CALCITE-834:
-------------------------------------
[~rhbutani], It would be helpful if you could write a one-line description of
each of RelOptPredicateList's 3 fields. I never understood what you meant by
"inferred" and "pulled up" - I should have pushed back when you contributed the
patch - and until I do I won't be able to maintain this code.
All the context you need is in
https://github.com/apache/incubator-calcite/commit/c33e602fa0c215e8a9f426781f9bb445fd9e6e94.
Just write the descriptions in this case and I will add them to the code.
[~jcamachorodriguez], Can you please close that pull request. I forgot to.
