             Summary: Add support for semi/anti joins
                 Key: ASTERIXDB-1299
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1299
             Project: Apache AsterixDB

          Components: Hyracks, Operators
            Reporter: Till Westmann

A number of operations (e.g. set operations) can be implemented efficiently using semi- or anti-joins. The hybrid hash join should be extended to support these join types as well.
