> Key: TAJO-316
> URL: https://issues.apache.org/jira/browse/TAJO-316
> Project: Tajo
> Issue Type: Improvement
> Components: planner/optimizer
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Labels: cbo
> Fix For: 0.8-incubating
>
> Attachments: TAJO-316.patch, TAJO-316_2.patch
>
>
> GreedyHeuristicJoinOrderAlgorithm is a default cost-based join order
> algorithm. It is designed only for inner joins, and it cannot deal with
> non-commutative joins, such as left/right/full outer join and semi/anti join.
> The main goal of this issue is to improve this algorithm to deal with them.
