Configuration Upgrade

When the size and configuration of your current cluster can no longer meet your actual needs, the cloud data warehouse UClickhouse provides a configuration upgrade feature to help you complete the upgrade adjustments of the cluster’s CPU, memory, and disk.

Kind reminder:

1. Configuration upgrades can only be performed when the cluster is running
2. During a configuration upgrade, the cluster will be unavailable for a few minutes, so please choose to upgrade during off-peak business hours

1. Log in to your UCloud Global account and access the User Console . Search for or select “Data Warehouse UDW Clickhouse” under all products, and navigate to the UClickhouse Data Warehouse Console . In the list, select Operation -> Configuration Upgrade.

​

2. In the cluster upgrade pop-up window, select the configuration items for node reconfiguration.

Kind reminder: Supports simultaneous upgrades of node computing specifications and disk. Note that disks can only be expanded, not reduced.

3. Click Confirm. After completing the payment on the order confirmation page, the cluster will change to Upgrading and the upgrade will be completed after a few minutes.
