Couchbase's History of Everything: DCP
Hiding behind an acronym (DCP), Couchbase has a secret superpower. Most people think of databases as storage locations data at a certain moment in time. But with Database Change Protocol (DCP), a Couchbase cluster can be viewed as an ongoing stream of changes.
Essentially, Couchbase can "rewind history" and replay everything that happened to the database from the beginning. In doing so, it can resolve any internal state since. In this article, we're going to cover why anyone would want to do such a crazy thing in the first place, and how we can exploit this superpower to do extra cool stuff with our documents.
