go-redis-pubsub

This library is a small specialized Go client for Redis pub/sub. I'm using it to support real-time high-throughput messaging between server instances when the expected channel count is large and the subscription pattern is very dynamic.

It's implemented using redigo.

Features

• Manages a subscription pool on behalf of the user to allow for concurrent channel subscription processing and automatic reconnection with exponential backoff.
• Attempts to mitigate SUBSCRIBE / UNSUBSCRIBE thrash by delaying unsubscription via a timer mechanism.
• Manages a send buffer and worker pool with the help of the redis.Pool implementation.
• Provides a handler callback interface for both subscribers and publishers.
