Durable Subscription for ActiveMQ topics

[n999]

Hello 

I've googled and can't find a definite answer around durable subscription with topics specifically as described here

http://activemq.apache.org/how-do-durable-queues-and-topics-work.html

Talend mentions this at a higher level - https://help.talend.com/reader/3o89P0YRxO5wQCS2w857gA/08zRT9tjWn9CJDi4XguVtQ

It seems in a talend DI job you can use a tJMSInput and set the "Enable Durable Subscription" option with a "ClientId" and "Subscriber Name". I've not tested this to see if this is the minimum required to make it work..

But what do you use with Talend Routes?

The cJMS component only has url options....is this where you configure the durableSubscriptionName? Do you provide a clientId as well?

It's not very clear what you need to do with a cJMS or generally to support "Durable Subscription" with DI Jobs and Routes...

Hopeful for any advice

many thanks

Hi, Is there already a solution available for this one?

Hi

Sorry - I ended up going back to connecting talend to queues by way of virtual topics. (https://tuhrig.de/queues-vs-topics-vs-virtual-topics-in-activemq/) so didn't need durable subscription to topics anymore.

No response from Talend either.

I have noticed that the cMQConnectionFactory camel component does have a "use retroactive consumer" tickbox (https://activemq.apache.org/retroactive-consumer) which sounds a bit like a durable subscription to a topic to me but only at first glance.....

Cheers
