{@link com.thinkaurelius.titan.diskstorage.IDAuthority} implementation assuming that the backing storesupports consistent transactions.
With transactional isolation guarantees, unique id block assignments are just a matter of reading the current counter, incrementing it and committing the transaction. If the transaction fails, another process applied for the same id and the process is retried. @author Matthias Broecheler (me@matthiasb.com)
