As most of you know, Couchbase is a database that provides users with a range of consistency and fault tolerance options to ensure that the state of their data meets certain criteria or guarantees. Users can specify varying levels of replication, persistence, replicas, sever groups, etc to guarantee that their data is durable, consistent, and correct under certain failure scenarios and cluster operations.

For the upcoming 6.5.0 release, new enhanced durability levels will provide users with even more safety and guarantees in the event of failures. Since we recognize that guarantees are only as good as their proof, we’re going to give an in-depth look at how we use Jespen, an industry-standard, to test database durability at Couchbase.
