GitHub user alamb added a comment to the discussion: Multiple 'group by's, one scan
There is some additional discussion on a similar sounding feature here: - https://github.com/apache/datafusion/issues/8777 Another potential approach is to fully materialize the input (`INSERT INTO temp_file.parquet SELECT ...`) or `CREATE TABLE temp as SELECT ...` Basically the tricky bit with an approach to share the scan is that in the general case the `CommonInput` would have to buffer the entire input anyways (if the consumers consumed at different rates) GitHub link: https://github.com/apache/datafusion/discussions/15982#discussioncomment-13158541 ---- This is an automatically sent email for github@datafusion.apache.org.
