Benchao Li commented on FLINK-16780:
------------------------------------

[~phoenixjiangnan] Thanks for the effort.

I also have an idea regarding dimension table. Currently, dimension table join 
does not have a hash distribution, which is not very friendly for cache. We 
also have some similar cases in our company, and we add a hash distribution for 
the join keys of left table.

If we can reach an agreement, I can create an issue to track this. Of course, 
we can add an optional table config to enable it, which is not enabled by 
default.
