> It seems to me like we have two known blocking issues now for 50.0.0 > > * [ ] [Regression: projection pushdown doesn't work as expected in DF50 #17513](https://github.com/apache/datafusion/issues/17513) > * [ ] [Nested Loop Join: Performance Regression in DataFusion 50 for Suboptimal Join Orderings #17488](https://github.com/apache/datafusion/issues/17488) I am unsure whether https://github.com/apache/datafusion/issues/17488 is really a blocking issue. After some further investigation and discussions, it seems like the problem is only related to a bad join ordering from our side (in this case: left side 1200 rows, right side 1 row) and relatively small data sets. The old algorithm handled this case better. Maybe a mention in the release notes and a pointer to the issue suffices?
