Round-robin message publishing using connection factories for JMS in 9.12
Horizontal scalability improvements have been introduced with the API for JMS, now allowing the configuration of round-robin connection factories. These factories allow clients to publish messages in a round-robin fashion, so that one message or transaction gets published to the first realm node or cluster, the next message to the next realm node or cluster, and so on.
These connection factories for JMS have the following limitations:
Event consumption is not supported through these factories so, for example, message listeners cannot be registered and consumers cannot be created via the sessions created from these connection factories.
The sessions created through these connection factories do not support distributed (XA) transactions.
