Using GCP secondary clusters (cross-region replication)

[agis]

GCP offers cross-regional clusters, which are essentially read-only clusters that replicate from another (the main) cluster. The secondary cluster has a totally different IP/network than the main one.

In that case, let's say someone wants to achieve the following setup:

• read queries go to the secondary cluster
• write queries go to the primary cluster

How would one go about it? Do we still use the ClusterClient? If so, what options should we be looking at to configure?

Thanks in advance!
