Lessons learned from building a Websocket server

• Redis

  320 64,962 9.7 C

  Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps.

  

The backbone of the data exchange between REST and WebSocket is a Redis instance. We are using a single Pub/Sub channel, which is the Source of Truth for the WebSocket Server. If a new resource is added via the REST API, the HTTP server will publish the payload alongside metadata in this channel. The WebSocket Server subscribes to the channel, processes the message, decides which client is allowed to receive the message, and sends it to the destined client.
