Redis keyspace notifications

Mon, 01 Jan 0001 00:00:00 +0000

Keyspace notifications allow clients to subscribe to Pub/Sub channels in order to receive events affecting the Redis data set in some way.

Examples of events that can be received are:

All the commands affecting a given key.
All the keys receiving an LPUSH operation.
All the keys expiring in the database 0.

Note: Redis Pub/Sub is fire and forget; that is, if your Pub/Sub client disconnects, and reconnects later, all the events delivered during the time the client was disconnected are lost.
