Now we use ``` DataGenOperator (num_instance=1) -> ResultSinkOperator(num_instance=1) ``` for loading/query tasks. This PR use a local shuffle to improve its parallelism and the plan is ``` DataGenOperator (num_instance=1) -> LocalExchangeSink (num_instance=1) -> LocalExchangeSource (num_instance=(cores / 2) -> ResultSinkOperator(num_instance=(cores / 2)) ```
