Class MaintenanceClient

Alarm activates, deactivates, and queries alarms regarding cluster health.

Defragment defragments a member's backend database to recover storage space.

Downgrade requests downgrades, verifies feasibility or cancels downgrade on the cluster version. Supported since etcd 3.5.

Hash computes the hash of whole backend keyspace, including key, lease, and other buckets in storage. This is designed for testing ONLY! Do not rely on this in production with ongoing transactions, since Hash operation does not hold MVCC locks. Use "HashKV" API instead for "key" bucket consistency checks.

HashKV computes the hash of all MVCC keys up to a given revision. It only iterates "key" bucket in backend storage.

MoveLeader requests current leader node to transfer its leadership to transferee.

Snapshot sends a snapshot of the entire backend from a member over a stream to a client.

Status gets the status of the member.
