public class SequenceManagerInMemoryImpl extends AbstractSequenceManager
Very fast in memory sequence manager implementation, only the first time an id was requested for a class, the manager query the database for the max id in requested column - all following request were performed in memory.
Limitations:Implementation configuration properties:
Property Key | Property Values |
seq.start | Set the start index of used sequences (e.g. set 100000, id generation starts with 100001). Default start index is 1. |
autoNaming |
Default was 'true'. If set 'true' OJB try to build a
sequence name automatic if none found in field-descriptor
and set this generated name as sequence-name
in field-descriptor. If set 'false' OJB throws an exception
if none sequence name was found in field-descriptor.
|
sequenceStart | Deprecated, use property 'seq.start'. Set the start index of used sequences (e.g. set 100000, id generation starts with 100001). Default start index is 1. |
