> This is a parent JIRA to track improvements on Flink Batch SQL, including parser, optimizer and execution.
> For example,
> 1. using Hive dialect and default dialect, some sql query would be translated into different plans
> 2. specify hash/sort aggregate strategy and hash/sort merge join strategy in sql hint
> 3. take parquet metadata into consideration in optimization
> 4. and so on
> Please note, some improvements are not limited to batch sql. Maybe streaming sql job could also benefits from some improvements in this JIRA.
