>          Issue Type: Bug
>          Components: COMP - Compiler
>    Affects Versions: 0.9.6
>            Reporter: Vijay Sarathy

> In the first version of CBO, the following operators were costed:
> SELECT
> UNNEST_MAP
> DATA_SCAN
> EXCHANGE
> INNER_JOIN
> The costing of these subset of operators provides sufficient information to generate good plans for a vast majority of queries.
> The costing of the other operators (like group by, order by, limit, etc.) needs to be completed for full coverage of all the operators.
