## Scale TiDB cluster

To scale TiDB cluster, modify `tikv_count` or `tidb_count` to your desired count, and then run `terraform apply`.
To scale TiDB cluster, modify `tikv_count`, `tikv_replica_count`, `tidb_count`, and `tidb_replica_count` to your desired count, and then run `terraform apply`.

> *Note*: Currently, scaling in is not supported since we cannot determine which node to scale. Scaling out needs a few minutes to complete, you can watch the scaling out by `watch kubectl --kubeconfig credentials/kubeconfig_<cluster_name> get po -n tidb`
