[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3586) SequenceHiLoGenerator generates values ahead of the actual sequence

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3586?page=c... ] Guenther Demetz commented on HHH-3586: -------------------------------------- Hi Krasimir, also I'm pretty sure this is not a bug. Huge "holes" in the ids are not to consider a problem: there exists definitely no paper which specifies that the id numbers must be contiguous. Also the justification that the number range will exhaust to early because of the huge "holes" is not firm (even in cluster environments). Holes in the numbers are an accepted and well known sideffect of the Hi-Lo algorithm, which is a compromise for maintaining performance (=avoid lock waits) also in high-concurrent scenarios (as a clustered environment even might be!) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
