Query to get all the MessageStartEvent the Engine is listening to

Hello,I have several processes deployed each having a unique MessageStartEvent start node.I need to map these Messages to certain Events thrown by my system. So for example I want to start a certain process when a document is created. I DON'T want to hardcode this, I need a way to configure this fro

It doesn't seem you actually need message start events, or at least I see very little value using it that way. Why don't you have your own (very simple) mapping from events -> process definition? That way you can easily make a UI on top of it.

Ok, so from what you wrote I understand that you're suggesting I crerate a simple mapping events -> process definition and in the mapping I should have something like:

On Created Document Event -> start the following process instances: Process1, Process3
On Deleted Document Event -> start the following process instances: Process5, and so on

So in the code it would be an iteration on some sort of structure (let's say a Map) and for each process mapped I should use startProcessInstanceBy[Key, Id, etc]… without the need of MessateStartEvents. Did I understood properly ?

If this is your suggestion, I am wondering, what is the primary use case for MessageStartEvent ?

Yes, that is indeed what I meant. But you can definitely still use message start events if you want to. However, I see little added value of using a message start event vs just having a mapping to process definition keys. Certainly if you need a dynamic UI like the one you describe: having a query on the message start events would still require you to write a mapping to those specific messages.
