**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Currently the `extract_join_keys` is only only invoked in the sql planner(join), then the join api of dataframe needs explictly specify the equijoin expression if they want equijoin. **Describe the solution you'd like** I would like to move the `extract_join_keys` to `optimizer`. **Describe alternatives you've considered** **Additional context** -- This is an automated message from the Apache Git Service.
