EJB Timer with cluster aware database persistence for JBoss EAP 7

Issue

• Is it possible to have standard EJB timers (according to the EJB 2.1 / 3 / 3.1 spec) with failover in a cluster?
• Is it possible to replace the file-persistence for EJB timer and use a different one?
• I want to ensure that persistent EJB timers are executed even when nodes in a cluster are down, what I need to configure for this?
• Does EAP 7 support fail-over for EJB timers? if yes, what configuration and infrastructure is required?
