> 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.
