In addition to significant performance and resilience enhancements Couchbase Lite 2.8 introduces enhanced support for peer-to-peer synchronization.
Using Couchbase Lite’s Peer-to-Peer Synchronization solution, you can build offline-first applications on edge devices that directly collaborate in secure bi-directional database synchronization without depending on centralized cloud-based control.
The solution provides an out-of-the-box implementation of a websocket based listener for use in peer-to-peer applications communicating over in IP-based networks.
The API has been enhanced with the following changes:
The Database Close method now automatically handles stopping open replicators, closing peer-to-peer websocket listener and removing observers for live queries.
The Database Delete method now automatically handles stopping open replicators, closing peer-to-peer websocket listener and removing observers for live queries.
The Replicator Is Document Pending method checks whether or not the document with the given ID has any pending revisions to push
The Replicator Get Pending Document method gets the Ids of all documents currently pending push
Meta Revision ID property is now available as a metadata property, which can be accessed directly in queries
