Our database provider, ClickHouse Cloud, requires us to perform a mandatory migration from ReplicatedMergeTree to SharedMergeTree engine. This upgrade will provide better performance, improved durability, and enhanced scalability for our services.

To minimize disruption, this maintenance is scheduled for Saturday during our least active hours.

Impact:
- Schema Registry operations (checks, publishing, and deletion) will be temporarily unavailable
- Hive Dashboard will be temporarily inaccessible
- Estimated downtime: 30 minutes

We recommend planning your schema updates around this maintenance window.

Thank you for your patience
