    Description

      The current physical operators for join have different naming rules as follows:

      • LeftOuterHashJoin, FullOuterHashJoin, ...
      • HashSemiJoin, HashAntiJoin

      This patch renames join operators with consistency as follows:

      • {Algorithm} {Join Type}

        Join

      For example, outer joins will have the following names:

      • HashLeftOuterJoin
      • MergeRightOuterJoin
      • HashFullOuterJoin

      This patch adds other join algorithms (left semi/anti hash join) to physical operators and adds In-subquery clause and exists predicate to Tajo algebra.
