Is it possible to register a listener for listen variable change (i.e variable create or update)?

[himly]

The variable query api of camunda is not enough to satisfaction us demand.

So I need to synchronize the variables from process instance to my db table for build us variable query api.

For to do that I need to configure a listener to listen variable change (i.e variable create or update) .

I search a lot at online but still not find useful information of this.
Someone can help me ?

Thanks you all.

Conditional boundary event over an activity will help you to configure Listener/Java Delegates when variable value changes. Various variable events are create/update/delete. You can configure more than one events as comma seperated lists.
