Hi, While exploring ReorderJoin optimization I wrote few unit test-like examples that demo how ExtractFiltersAndInnerJoins.flattenJoin [1] works.
I've been wondering if the examples could become unit tests instead. There are 6 different join-filter plan combinations using Catalyst DSL to create the plans. I'm wondering if I should file a task in JIRA for this or just send a pull request? I'd appreciate some guidance.
