> 1. In non kettle flow memory usage is very high in sort step, because it keeps lots of per every thread, it leads to GC issue.
> 2. Close all record readers which are opened while loading data.
> 3. Carbontable cannot found during data load because it is not loaded in executor, so add the carbon table in executor side to memory.
> 4. Prefetch the data in inputprocessor step to avoid IO waiting.
