could I config an queue to no persistence, others to persistence
Hi, everybody:
I'm an Chinese, and not good at English.
I have a question, I config an embedded broker, could I config an queue to no persistence, others to persistence? Or could I config 2 emmbedd brokder to resolve it? How to config it?

In fact, I use spring to config jms. I find I could set property 'deliveryPersistent' to JmsTemplate.

As I understood, when you send a persistent message it is a synchronous call but when you send a non-persistent message it is asynchronous. So adding the persistent plugin does not actually give you the same guarantee that actually sending the messages as persistent does. i.e. you could lose a message before it gets to the plugin.
You are doing the opposite so you don’t need to worry about the safety issue. However you will not get any speed improvements when queuing the message by using the non-persistent plugin, obviously...

persistence is a property of the message, so you could use a plugin to ensure deliveryMode is NON_PERSISTENT for all messages to specific destinations.
There is an existing plugin that enforces persistence for all messages, you would need to extend that plugin to add some filtering, included/excluded. Would be a nice enhancement.
Existing persistenceMode plugin for reference:
