It exposes a scale-out, key-value store with managed cache for sub-millisecond data operations, purpose-built indexers for efficient queries and a powerful query engine for executing SQL-like queries. For mobile and Internet of Things environments Couchbase also runs natively on-device and manages synchronization to the server. ###### ![n1ql ansi join example](_images/n1ql-ansi-join-example.png) ##
