[GitHub] [calcite] julianhyde commented on pull request #2800: [CALCITE-3890] Derive IS NOT NULL filter for the inputs of inner join

   Please take a look at https://github.com/julianhyde/calcite/tree/3890-join-is-not-null. I prototyped how this change would look if we let `RelBuilder.filter` do the work. (It needed a change to `RelBuilder` to simplify using the current `RelNode`'s pulled up predicates.)
