    Description

      From https://issues.apache.org/jira/secure/attachment/12778890/BucketedTables.pdf:

      Filter on sorted data

      If the data is sorted by a key, filters on the key could stop as soon as the data is out of range. For example, WHERE ticker_id < “F” should stop as soon as the first row starting with “F” is seen. This can be done adding a Filter operator that has “stop if false” semantics. This is generally useful.
