04:49 Hi everyone, I’m trying to gain some insight into distributed joins in CockroachDB, but I find the documentation/write-ups a bit lacking in this area.
Is it true that for distributed join queries in CockroachDB, the only supported algorithm is “merge join”?
The short answer is no, we also have implemented hash joins though we prefer merge joins since they are more performant. Does that answer your question, or were you interested in our behavior in a specific scenario?
