@navis thanks for your nice work!
In overall, it looks good.
However, since this is a new feature, we need to test the patch thoroughly.
First of all, it is required to add some tests for this issue.
I think that you can enable your concurrent execution option for query
tests. It will be easier than adding new test functions.
In addition, I wonder how much Tajo's performance is improved with this
feature. Can you share any performance test results?
