Installing etcd

To ensure that the etcd version used for compilation meets the Milvus requirements, it is advised to install etcd 3.5.0 or later.

etcd is a distributed key-value data storage system used for configuration management, service discovery, and distributed coordination. It is an important component for the Milvus runtime, especially in a distributed deployment environment. Correctly configuring and using etcd not only improves system reliability and performance, but also simplifies management and maintenance.
