What would you like to be added?

The etcd client in milvus accesses the etcd node namd etcd-0. The etcd-0 node is unavailable due to network partitioning and is in a state of repeated election, cannot apply write operations. The request timeout of the etcd client is too long (9 seconds in logs), so the process have been locked on the requesting node.
