Couchbase Lite provides the ability to locally synchronize an instance of a remote database that resides on a Couchbase Server.
All or part of it. The Sync takes place through the Sync Gateway, which communicates with Couchbase. Also keep in mind that Couchbase is schemaless database, so the structure of the document is not bound to the bucket. To mutate the data, you can look at INSERT, UPDATE and UPSERT statements.
To facilitate the development of reactive applications, Couchbase Lite can be asynchronously notified of changes to the database, of replication status at the granularity of an individual document, or of updates.
