SequenceHiLoGenerator

Class Overview

seqhilo

An IdentifierGenerator that combines a hi/lo algorithm with an underlying oracle-style sequence that generates hi values. The user may specify a maximum lo value to determine how often new hi values are fetched.

If sequences are not available, TableHiLoGenerator might be an alternative.

Mapping parameters supported: sequence, max_lo, parameters.
