-----------------------------------
Summary: Change QueryCompiler get column expressions process from
serial to parallel.
Key: PHOENIX-4398
URL: https://issues.apache.org/jira/browse/PHOENIX-4398
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.11.0, 4.13.0
Reporter: Albert Lee
Fix For: 4.13.0, 4.11.0
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.
