Can multiple GCP Dataproc clusters use same metastore?

Planning to use Dataproc cluster with Dataproc Metastore.

Questions:

• when we delete Dataproc clusters, would Dataproc Metastore continue to remain available?
• Can two different Dataproc clusters in same region, use same Dataproc Metastore?
• Can two different Dataproc clusters on different region, use same Dataproc Metastore?

Posting this as a community wiki:

As what Dagang said, the answer is to use an external metastore that persists outside of the cluster lifecycle. You can do this in two ways:

Using Dataproc Metastore Service

Using Cloud SQL proxy
