Aiven for ClickHouse® 26.3 available in Early Availability

Aiven for ClickHouse 26.3 LTS is available in Early Availability. You can use it for new services or upgrade an existing service from version 25.8.
This release enables asynchronous inserts by default, makes full-text search generally available, introduces materialized common table expressions (CTEs), improves Map lookup performance, and includes upstream changes from versions 25.9 through 26.3.

Before upgrading, Aiven checks the service for compatibility issues. Review the compatibility changes, removed features, and changed defaults, and test the upgrade on a service fork first.

For details, see Upgrade to Aiven for ClickHouse 26.3 and the announcement blog.
