Optimize replication by removing covered parts from fetched parts to prevent replication delay growth.
Why it matters
This feature addresses the issue of replication delays potentially increasing over time. By removing covered parts from fetched parts during replication, it reduces unnecessary data processing and storage, thereby improving replication efficiency and consistency.How to use it
This optimization is applied automatically in the replication process; users do not need to manually enable it. It is integrated into the ClickHouse replication mechanism to enhance performance transparently.
