[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-2471) create a set of "enhanced" generators

create a set of "enhanced" generators ------------------------------------- Key: HHH-2471 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2471 Project: Hibernate3 Type: New Feature

Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.2.3

Specifically, the build the following two capabilities: 1) a sequence "style" generator targetting cross db portability in a better fashion that native. specifically, use sequences if dialect supports them; otherwise fall back to a table-based implementation *with the same characteristics*. 2) ability to easily apply "optimizations" without needing to create a whole new generator. by optimizations i mean wrapping in a hilo or "pooled" algorithm. This will result in two new generators: 1) SequenceStyleGenerator 2) SegmentedTableGenerator (better names welcome) Specifically, SequenceStyleGenerator by itself fulfills requirement #1. It does also accept pluggable optimizers. SegmentedTableGenerator is to be a rewrite of the current MultiTableHiLoGenerator which performs the same basic function as MultiTableHiLoGenerator in terms of table layout in order to store multiple (or segmented) sequences. However, it will also take advantage of the pluggable optimizers.
