 ## A case of planning TiDB clusters
 
-This is an example of deploying five clusters (each cluster has 3 PDs, 3 TiKVs, and 2 TiDBs), where PD is configured as 2C 4GB, TiDB as 8C 32GB, and TiKV as 8C 32GB. There are seven Kubernetes nodes, three of which are both master and worker nodes, and the other four are purely worker nodes. The distribution of each component is as follows:
