We are currently experiencing delays with applying configuration and Kafka Integration changes to Clickhouse clusters via Terraform, the Cluster Management API and Management Console. During this time, making configuration changes to Clickhouse clusters may take longer than usual. Our team is actively working on resolving this problem and we apologise for any inconvenience caused. Existing customer clusters are unaffected, and the Monitoring API and Prometheus API are operational. Additional details will be provided as they become available. If you have an urgent matter, please reach out to us via the support portal (support.instaclustr.com) or email ([email protected]).

We have additionally identified that making changes to Kafka User via Terraform, the Cluster Management API, and the Management Console is also experiencing delays. We have implemented a fix that has significantly reduced the delays experienced when applying configuration and Kafka integration changes to Clickhouse clusters and also reduced the delays when making changes to Kafka Users on Kafka Clusters via Terraform, the Cluster Management API, and the Management Console. We will continue to monitor the results of the fix and provide additional updates as they become available.
