>
> When QueryCompiler compile a select sql, the process of getting column
> expressions is a serial process. The performance is ok when the table is
> narrow. But when compile a wide table(e.g. 130 columns in my use case), The
> time-consuming of this step is very high, over 70ms. So I change
> TupleProjector(PTable projectedTable) from serial for loop to parallel future.
