Resolved
Routing to multiple databases has improved the handling of the load to the raw api.
Monitoring
The service has improved after a database migration job was completed. Cognite Engineering is observing the system to see if further improvements are needed.
Investigating
The engineering team has deployed a solution that enable us to re-route some of the load to different databases. Cognite has been in contact with a customer that generates substantial load to make use of this routing feature as a workaround.
Customers may still experience degraded performance for transformations and RAW. (Transformations suffers when RAW is not performing.)
Investigating
The engineering team is currently investigating an incident where the RAW service is failing to keep up with the load. The backend database is not able to keep up with the incoming traffic.
The engineering team is currently working on a plan to increase the backend performance by sharding across several databases. Updates on the timeline will be posted here.
