* Add ATTACH PARTITION FROM table for MergeTree. [#CLICKHOUSE-3546] * Implemented replicated case on non-leader replica. [#CLICKHOUSE-3546] * Disable merges in the dropping range. [#CLICKHOUSE-3546] * DROP PARTITION is atomic and simpler now. [#CLICKHOUSE-3546] * Implemented more SYSTEM queries. [#CLICKHOUSE-2931] [#CLICKHOUSE-3546] SYSTEM queries: RESTART REPLICAS SYNC REPLICA db.name STOP MERGES [db.name] START MERGES [db.name] STOP FETCHES [db.name] START FETCHES [db.name] STOP REPLICATED SENDS [db.name] START REPLICATED SENDS [db.name] STOP REPLICATION QUEUES [db.name] START REPLICATION QUEUES [db.name] * Fixed a bunch of bugs in REPLACE PARTITION. [#CLICKHOUSE-3546] * Add tests for REPLACE PARTITION and SYSTEM. [#CLICKHOUSE-3546] * Add system.part_log logging. [#CLICKHOUSE-3546] * Fixed long wait in SYNC REPLICA. [#CLICKHOUSE-3546] * Add requested changes. [#CLICKHOUSE-3546] Fixed clickhouse-client bad return code. * Add requested chenges. [#CLICKHOUSE-3546] * Add requested chenges. [#CLICKHOUSE-3546]
