 The hard part is to make this concept production-ready, efficient, flexible and available from different application environments. Centrifugo is a mature solution that already helped many projects with adding real-time features and scale towards many concurrent connections. Centrifugo provides a set of features not available in other open-source solutions in the area:
 
-* Real-time transports: WebSocket, HTTP-streaming, Server-Sent Events (SSE), GRPC, WebTransport
-* Built-in scalability to many machines with Redis, KeyDB, Nats, Tarantool
+* Efficient real-time transports: WebSocket, HTTP-streaming, Server-Sent Events (SSE), GRPC, WebTransport
+* Built-in scalability with Redis (or Redis Cluster, or Redis-compatible storage – ex. AWS Elasticache, KeyDB, DragonflyDB, etc), or Nats.
 * Simple HTTP and GRPC server API to communicate with Centrifugo from the app backend
 * Flexible connection authentication mechanisms: JWT and proxy-like
 * Channel subscription multiplexing over a single connection
 * Different types of subscriptions: client-side and server-side
 * Various channel permission strategies, channel namespace concept
-* Hot message history in channels, with automatic message recovery upon reconnect
+* Hot message history in channels, with automatic message recovery upon reconnect, cache recovery mode (deliver latest publication immediately upon subscription)
 * Delta compression in channels based on Fossil algorithm
 * Online channel presence information, with join/leave notifications
 * A way to send RPC calls to the backend over the real-time connection
