Clarification required on maximum number of consumers

raviteja457 Jun 10, 2013 9:21 AM

Hi ,

I have a topic called notificationTopic and i have my hornetq servers running in a cluster mode ,My environment is on AWS EC2 with JBOSS.So, i have the following scenario's

1) Multiple consumers (More than 2000 to 3000) connecting to notificationTopic and receiving the specific message using message selectors.

2) One or Two MDB's connecting to notificationTopic and processing the request using ThreadPools.

Could you please suggest what will be the maximum number of consumers that a single topic can have.....?Somebody help us pros and cons of above scenarios and which one will be a good design...?

a consumers subscription is just a queue on the server, how many you can have depends on memory available, how you have your flow control set up, how many messages you are sending etc etc

If you are asking which of 1 and 2 is best well there is really no difference, an MDB is just a consumer so it would be dependant on how you wrote your client consumer code
