Releases a Server Load Balancer (SLB) instance for a specified ApsaraDB for ClickHouse cluster.

Usage notes

After you release an SLB instance, simple load balancing is performed on inbound traffic based on the domain name. The health status of all nodes is no longer checked. As a result, unavailable nodes may fail to be detected, and normal requests may be routed to the unavailable nodes. This causes failures of some read and write requests.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
