case class PartitionIdentityValueGenerator(start: Long, step: Long, highWaterMarkOpt: Option[Long]) extends Product with Serializable
Generator of IDENTITY value for one partition.
- start
The configured start value for the identity column.
- step
IDENTITY value increment.
- highWaterMarkOpt
The optional high watermark for the identity value generation. If this is None, that means that no identity values has been generated in the past and we should start the identity value generation from the
start.
