[jira] [Updated] (TAJO-232) Rename join operators and add other
join operators to PhysicalPlanner
[ https://issues.apache.org/jira/browse/TAJO-232?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyunsik Choi updated TAJO-232:
------------------------------
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.
