* Improve performance of SELECTs with active mutations
getAlterMutationCommandsForPart() can be a hot path for query execution
when there are pending mutations.
- LOG_TEST - it is not only check one bool, but actually a bunch of
atomics as well.
- Return std::vector over std::map (map is not required there) - no
changes in performance.
- Copy only RENAME_COLUMN (since only this mutation is required by
AlterConversions).
And here are results:
run|result
-|-
SELECT w/o ALTER|queries: 1565, QPS: 355.259, RPS: 355.259
SELECT w/ ALTER unpatched|queries: 2099, QPS: 220.623, RPS: 220.623
SELECT w/ ALTER and w/o LOG_TEST|queries: 2730, QPS: 235.859, RPS: 235.859
SELECT w/ ALTER and w/o LOG_TEST and w/ RENAME_COLUMN only|queries: 2995, QPS: 290.982, RPS: 290.982
But there are still room for improvements, at least MergeTree engines
could implement getStorageSnapshotForQuery().
