v.23.1Improvement
Don't Report Concurrent Merge Errors in system.errors
Don't report errors in system.errors due to parts being merged concurrently with the background cleanup process. #44874 (Raúl Marín).Why it matters
During concurrent merges and background cleanup, operations on parts could generate non-critical errors reported insystem.errors, causing noise and potential confusion. This feature prevents those errors from being reported, improving error log clarity and reliability for users.How to use it
This improvement is applied internally within ClickHouse and requires no user action to enable. The system will automatically avoid reporting these specific concurrent merge and cleanup errors insystem.errors.
