Self-hosted ClickHouse no longer accumulates unbounded system-log telemetry (metric_log, text_log, asynchronous_metric_log, ...) that eventually pins the CPU in a background merge-retry loop on the recommended machine size; query_log and error_log are kept with a TTL, and the low-memory profile settings now actually apply (moved from config.d to users.d).
|
||||
Self-hosted ClickHouse now disables its unbounded internal telemetry tables and keeps query/error logs on a bounded retention, fixing runaway CPU and memory usage on the recommended machine size. Existing self-hosted deployments must drop the previously written disabled log tables separately to reclaim disk.
