Azat Khuzhin	a75559aa36	Avoid recreation of system.asynchronous_metric_log (due to difference in codec) ... From the log: 2022.04.29 12:33:40.397528 [ 486 ] {} <Debug> SystemLog (system.asynchronous_metric_log): Existing table system.asynchronous_metric_log for system log has obsolete or different structure. Renaming it to asynchronous_metric_log_352. Old: CREATE TABLE system.asynchronous_metric_log (`event_date` Date CODEC(Delta(2), ZSTD(1)), `event_time` DateTime CODEC(Delta(4), ZSTD(1)), `metric` LowCardinality(String) CODEC(ZSTD(1)), `value` Float64 CODEC(Gorilla, ZSTD(3))) ENGINE = MergeTree PARTITION BY toYYYYMM(event_date) ORDER BY (metric, event_date, event_time) SETTINGS index_granularity = 8192 New: CREATE TABLE system.asynchronous_metric_log (`event_date` Date CODEC(Delta(2), ZSTD), `event_time` DateTime CODEC(Delta(4), ZSTD), `metric` LowCardinality(String) CODEC(ZSTD), `value` Float64 CODEC(Gorilla, ZSTD(3))) ENGINE = MergeTree PARTITION BY toYYYYMM(event_date) ORDER BY (metric, event_date, event_time) SETTINGS index_granularity = 8192 As you can see the difference in default ZSTD level. P.S. I decided not to fix the printer, since this may introduce changes in metadata, that may lead to changes in metadata between ZooKeeper and clickhouse server.

Azat Khuzhin	aee034a597	Use explicit template instantiation for SystemLog ... - Move some code into module part to avoid dependency from IStorage in SystemLog - Remove extra headers from SystemLog.h - Rewrite some code that was relying on headers that was included by SystemLog.h v2: rebase v3: squash move into module part with explicit template instantiation (to make each commit self compilable after rebase)	2022-01-10 22:01:41 +03:00
