title: Could i use couchbase for token generation and validation systems
body: <p>I am designing a high volume service which essentially works as a token creation and validation service. Today we use SQL based databases which are fast failing to scale and the alternative that we are looking at is Couchbase server (memcached). However, the use case is the token generated by this service is sent to other services where the token will be used for authentication. If the replication is not fast enough, the authentication fails. Is there a simpler means to achieve this either via code or any other alternatives is also welcome. This seems to us to be a "read-your-own-write" use case. </p>
