i am reading the design of cockroach and have this question.
is cockroach-db possibly to support query push down or shard colocated  for join query?
i am a user of citus. and i think most of the time, much of simply query could be push down
 to one node, and excuted localily, with good performance.

is it possibly for cockroach  or impossibly for some reason?

We distribute query processing and we do try to move as much of the processing as possible close to the data. But it's hard to make a general statement. Do you have a more specific usecase we could discuss?
