* Add data migration for moving to VersionedCollapsingMergeTree This has been tested locally and partially on staging. Still requires a bit of work to verify. Verification query: ``` SELECT main._partition_id, tmp.count, main.count FROM ( SELECT _partition_id, count() AS count FROM sessions_v2_tmp_versioned GROUP BY _partition_id ) AS tmp FULL OUTER JOIN ( SELECT _partition_id, count() AS count FROM sessions_v2 GROUP BY _partition_id ) AS main ON (tmp._partition_id == main._partition_id) ORDER BY main._partition_id ``` * Add an early exit to migration * cluster? extract common code |
