Query about Jdempotent States

[IOhacker]

Jdempotent supports the following states and conditions?

1. unlocked - lock doesn't exist and can be locked
   locked - lock exists and is used by a process to guard a write
   i. typically we set a ttl on the lock according to the amount of time the write would take
   ii. i.e. DB write in JTA transaction of 120 seconds would use a 120 second ttl
   iii. if the lock doesn't transition to failed/committed in this time the lock is expired
2. expired - lock expired TTL (vm, jvm, thread error)
   i. a retry can transition this from expired to locked
3. failed - the owning process released with error (no DB connection, etc)
   i. a retry can transition this from failed to locked
4. committed - write process completed all work, this is an immutable state

Now jdempotent has not locking system, but it will be good. i will get this task to backlog
