Hi Ron
OFGC looks like an exciting optimization, looking forward to its completion
in Flink!
A small question, do we consider adding a benchmark for the operators to
intuitively understand the improvement brought by each improvement?
In addition, for the implementation plan, mentioned in the FLIP
Hi, Jark
Thanks for your feedback, according to my initial assessment, the work
effort is relatively large.
Moreover, I will add a test result of all queries to the FLIP.
Best,
Ron

Hi Ron,
Thanks a lot for the great proposal. The FLIP looks good to me in general.
It looks like not an easy work but the performance sounds promising. So I
think it's worth doing.
Besides, if there is a complete test graph with all TPC-DS queries, the
effect of this FLIP will be more intuitive.
Hi, Jinsong
Thanks for your valuable suggestions.
Best,
Ron

Thanks Ron for your information.
I suggest that it can be written in the Motivation of FLIP.

Hi, Jingsong
Thanks for your review. We have tested it in TPC-DS case, and got a 12%
gain overall when only supporting only Calc&HashJoin&HashAgg operator. In
some queries, we even get more than 30% gain, it looks like an effective
way.

Ron

Thanks Ron for the proposal.
Do you have some benchmark results for the performance improvement? I
am more concerned about the improvement on Flink than the data in
other papers.
Best,
