------------------------------------
Summary: Prevent translation of non-equi joins in DataSetJoinRule
Key: FLINK-3934
URL: https://issues.apache.org/jira/browse/FLINK-3934
Project: Flink
Issue Type: Bug
Components: Table API
Affects Versions: 1.1.0
Reporter: Fabian Hueske
Assignee: Fabian Hueske
At the moment, also non-equi joins are translated into {{DataSetJoin}}s.
To prevent such plans from being picked, we assign huge costs and eventually
fail their translation into DataSet programs.
A better solution is to prevent a non-equi join from being translated into a
{{DataSetJoin}} in the {{DataSetJoinRule}}.
