public class NativeJDBCSeq extends AbstractJDBCSeq implements Configurable
JDBCSeq
implementation that uses a database sequence
to generate numbers.
Supports allocation (caching). In order for allocation to work properly, the database sequence must be defined
with INCREMENT BY value equal to allocate * increment.JDBCSeq
