Looking for advice/pro's/con's on using the memory cache servers for pub/sub esp wrt a high-throughput system ( 1000's of updates/sec )
Coherence seems to have pub/sub as a use-case, not sure about the others
Would love to get some real-world input !
I would like you to offer Hazelcast Distributed Topic. Very light weight distributed pub/sub messaging system. 1000 updates/sec isn't much at all.
If it's pub/sub you're after you can also use a messaging solution such as RabbitMQ. Very high throughput and scales well.
Subscribe to a queue and react to messages published to them. Client libraries for a variety of languages are usually available making these systems useful for cross-platform distribution as well.
