I have Quarkus Java app which uses scheduler and runs every 15 second inside the scheduler reading a query and updating etc…my concern is I want to understand if this scheduler is shared amongst instances or each instance create its own scheduler so if this is the case it might run into concurrency issues

I thought of azure storage blob which says that only one instance at a time takes a lock so there is only one scheduler at e time either on first instance or second but not on both, but this is the case if quarks scheduler is really created separately on both two instances?
