+Prebid Cache requires a backend data store which enforces TTL expiration. The following storage options are supported: Aerospike, Cassandra, Memcache, and Redis/Redis sentinel. You're welcomed to contribute a new backend adapter if needed.
 
 There is also an option (enabled by default) for a basic in-memory data store intended only for development. This backend does not support TTL expiration and is not built for production use.
