@alamb reimplemented the logic based on your suggestion in https://github.com/apache/arrow-datafusion/pull/605#issuecomment-866862804. Turns out there are many more edge-cases that need to be handled for using join other than wildcard expansion: * predicate push down on join columns * normalize unqualified column expressions that reference join columns with qualifiers I have implemented support for all these edge-cases, but decided to leave out the wildcard expansion change as a follow up PR to keep the diff easier to review. UPDATE: filed https://github.com/apache/arrow-datafusion/pull/678 as follow up. -- This is an automated message from the Apache Git Service.
