Which version of CockroachDB was that? A few years ago it had a rudimentary heuristic optimizer that made plenty of poor choices. Today it has a quickly improving cost-based optimizer that makes much better choices. Each release now has significant jumps in which kinds of queries it can produce fast plans for. |
