Jackie-Jiang opened a new pull request, #16478: URL: https://github.com/apache/pinot/pull/16478
Currently REGEXP_LIKE without FST/IFST index always performs raw value scan even with dictionary. We don't match on dictionary id to avoid scanning the entire dictionary. This is not efficient when the dictionary is small, where we prefer scanning the dictionary and perform matches on dictionary ids. This is particularly useful for new added columns/virtual columns with single element dictionary. This PR adds a threshold (10000) to decide whether to scan the dictionary when evaluating `REGEXP_LIKE` predicate. -- This is an automated message from the Apache Git Service.
