replicated_fetches_min_part_level
Version history
| Version | Default value | Comment |
|---|---|---|
| 26.4 | 0 | New setting |
Minimum part level to fetch from other replicas. Parts with level below this threshold are postponed (kept in the replication queue and re-evaluated each scheduling cycle, not permanently skipped). Use 1 to postpone fetching level-0 (unmerged) parts, reducing replication overhead during heavy ingestion. Default: 0 (fetch all parts regardless of level).
replicated_fetches_min_part_level_timeout_seconds
Version history
| Version | Default value | Comment |
|---|---|---|
| 26.4 | 300 | New setting |
Timeout in seconds after which a part below replicated_fetches_min_part_level will be fetched anyway. Use 0 to disable the timeout (parts below the minimum level are postponed indefinitely until merged). Default: 300 (force fetch after 5 minutes).
