   - Whether compaction succeeds or not, this process repeats for every 1/10 of given compaction period. If compaction succeeds, it just removes compacted revision from historical revision records.
 - Add [`etcd --grpc-keepalive-min-time`, `etcd --grpc-keepalive-interval`, `etcd --grpc-keepalive-timeout`](https://github.com/etcd-io/etcd/pull/8535) flags to configure server-side keepalive policies.
 - Serve [`/health` endpoint as unhealthy](https://github.com/etcd-io/etcd/pull/8272) when [alarm (e.g. `NOSPACE`) is raised or there's no leader](https://github.com/etcd-io/etcd/issues/8207).
