Introducing Couchbase Edge Server

      +

      Couchbase Edge Server is a lightweight standalone database for resource-constrained edge, based on Couchbase Lite Core.

      With Couchbase Edge Server, you can perform scalable, offline-first data sync at the edge in resource constrained environments.

      edge server architecture

      1. REST API: A RESTful interface that allows any HTTP client, including browser applications, to access and query data.

      2. Remote Sync: Enables Couchbase Edge Server to sync data with remote upstream Sync Gateway/App Services clients over WebSockets based replication protocol.

      3. Edge Sync: Allows downstream Couchbase Lite applications at the edge to sync data with Couchbase Edge Server.

      4. High Availability (HA): You can connect multiple Edge Servers via their 'upstream' and 'downstream' sync interfaces; this can let one server act as a backup for another, or keep multiple servers synced. Conflicts will be rejected.

      Couchbase Edge Server possesses the following features:

      • Compact and lightweight: ~10 MB codebase, typically uses < 50 MB RAM.

      • Flexible data handling: Serves existing Couchbase Lite database files, or can create its own CRUD-based document access.

      • Real-time updates: Push notifications for data changes on the changes feed to save bandwidth caused by polling and reduce latency.

      • Advanced querying: Supports SQL++ queries.

      • Local synchronization: Acts as a database sync server for local Couchbase Lite clients.

      • Upstream integration: Functions as a database sync client for upstream Sync Gateway, Capella App Services, or other instances of Edge Server.
