-----------------------------
Resolution: Unresolved
> change DataSetCost to FlinkRelOptCost
> -------------------------------------
>
> Key: FLINK-6150
> URL: https://issues.apache.org/jira/browse/FLINK-6150
> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Kurt Young
> Priority: Major
>
> Currently the only {{RelOptCost}} we have is {{DataSetCost}}, but it's also
> used in StreamTableEnvironment. And once we introduce an additional logical
> operator layer, we also need a cost representation. Renaming {{DataSetCost}}
> to {{FlinkRelOptCost}} and use it in both logical and physical environment
> seems to be a possible solution.
