def commitState(state: String, name: String)(implicit ec: ExecutionContext): Future[Unit]

Commit a new state to be associated with the lock - workers use this state information to coordinate the work progress across invokations.
Commit a new state to be associated with the lock - workers use this state information to coordinate the work progress across invokations.
The date of the last run is not updated by this call because a commit is just intended to reduce re-processing in case of failure.

def initLock(name: String, checkInterval: FiniteDuration = 20.seconds, ttl: FiniteDuration = 240.seconds, enabled: Boolean = false)(implicit ec: ExecutionContext): Future[Boolean]

Initialize a lock entry with default / provided lock meta data.
Initialize a lock entry with default / provided lock meta data. This is used by the first singleton manager that discovers that a given lock is not yet present.
Uses Cassandra CAS functionality to ensure only one manager is initializing the lock.

Try to acquire a specific lock. This uses Cassandra CAS feature to ensure that only one singleton manager can grab the lock.
Uses cross-data centre serial consistency for now.
