<SettingsInfoBlock type="UInt64" default_value="0" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "26.4"},{"label": "0"},{"label": "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).

<h2 id="replicated_fetches_min_part_level_timeout_seconds">

<SettingsInfoBlock type="UInt64" default_value="300" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "26.4"},{"label": "300"},{"label": "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).
