Hibernate version: 3.1


Hi,

The hibernate document says which is available in the following link http://www.hibernate.org/hib_docs/v3/re ... ml_single/ says
the built-in generator "increment" should not be used in cluster.

increment

generates identifiers of type long, short or int that are unique only when no other process is inserting data into the same table. Do not use in a cluster.

Does this mean we should not use in a database Cluster environment or in application cluster ( JVM ) environment ?

Thanks,
Dinesh

Increment is an in memory process (see the code to confirm). Thus obviously, it does not hit the db (other than getting the first starting value at SessionFactory startup) when allocating the next number.
