@hvanhovell Thank you for the first review. Because Spark SQL doesn't support a convenient way to construct logical plan for each API. We had to create Dataset/Dataframes in the planner. There are two ways to avoid create duplicate Dataset/Dataframes: 1. Add many new logical node and sql's dataset API for return logical plan directly. This job affects SQL mode deeply. 2. We only create Dataset/Dataframes once in planner and use it for execution. This PR follows this way. -- This is an automated message from the Apache Git Service.
