We have completed our maintenance on the production RunReveal Multi-tenant ClickHouse Database.
We encountered a minor unforeseen disruption related to cache invalidation when doing the maintenance, resulting in sporadic MemoryLimitExceeded errors.
Ingestion was delayed up to 15 minutes while we investigated but has now resumed and is fully caught up. No data was lost.
We expect the MemoryLimitExceeded errors to be fully resolved shortly as the caches recover, and will continue to monitor the cluster health.
We'll update this report once we're confident they are no longer occurring.
