ClickHouse Keeper now persists meta-information about keeper servers to disk, enhancing reliability during restarts.
Why it matters
This feature addresses the challenge of operating keeper nodes by ensuring that meta-information about keeper servers is saved to disk. It helps maintain state and simplifies management when all keeper nodes are shut down or restarted simultaneously.How to use it
The persistence of keeper servers meta-information is enabled automatically in ClickHouse Keeper with this update. No additional configuration is required; simply restart the keeper nodes as usual, and the metadata will be retained on disk.
