 ConfigNode is the control node of the cluster, which manages the cluster's node status, partition information, etc. All ConfigNodes in the cluster form a highly available group, which is fully replicated.
 
+Notice：The replication factor of ConfigNode is all ConfigNodes that has joined the Cluster. Over half of the ConfigNodes is Running could the cluster work.
+
 DataNode stores the data and schema of the cluster, which manages multiple data regions and schema regions. Data is a time-value pair, and schema is the path and data type of each time series.
 
 Client could only connect to the DataNode for operation.

 ConfigNode 是集群的控制节点，管理集群的节点状态、分区信息等，集群所有 ConfigNode 组成一个高可用组，数据全量备份。
 
+注意：ConfigNode 的副本数是集群当前加入的 ConfigNode 个数，一半以上的 ConfigNode 存活集群才能提供服务。

 DataNode 是集群的数据节点，管理多个数据分片、元数据分片，数据即时间序列中的时间戳和值，元数据为时间序列的路径信息、数据类型等。
