Examples

Subscribe to a Redis channel:

// Subscribe to a channel with a callback handler
RedisSubscribe(
    cache = "myRedisCache",
    channel = "notifications",
    callback = function( message ) {
        println( "Received message: " & message );
    }
);

Handle multiple message types:

// Subscribe to events channel and parse JSON messages
RedisSubscribe(
    cache = "myRedisCache",
    channel = "events",
    callback = function( message ) {
        var event = deserializeJSON( message );

        switch( event.type ) {
            case "user.created":
                println( "New user created: " & event.userId );
                break;
            case "user.updated":
                println( "User updated: " & event.userId );
                break;
            default:
                println( "Unknown event type: " & event.type );
        }
    }
);

Subscribe to multiple channels:

// Subscribe to multiple channels with pattern matching
RedisSubscribe(
    cache = "myRedisCache",
    channel = "events:*",
    callback = function( message ) {
        println( "Event received: " & message );
    }
);
