Launching a Replica Cluster

How to create a replica of a ClickHouse® cluster
Launch New Cluster

WARNING: FOR ADVANCED USERS ONLY.

ClickHouse® clusters can be replicated easily. A replica can include the same database schema as the original cluster, or it can be launched without the schema.

NOTE: Be aware this a true replica, not a one-time copy. Any changes made to the replica’s data will be replicated back to the source cluster.

This menu item starts a slightly modified version of the Launch Cluster Wizard. The only difference is on the ClickHouse Setup panel:

Replicate the cluster schema

Figure 1 - The modified ClickHouse Setup panel

You have the option to replicate the schema of the existing cluster. With that exception, this version of the Launch Cluster Wizard is identical to the one covered in the Launch Cluster Wizard documentation.

Once you click Launch on the Review & Launch tab at the end of the wizard, the replica cluster will be available within a few minutes.
