@TableGenerator does not increment pkColumnValue by allocationSize ------------------------------------------------------------------ Key: HHH-3407 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3407 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6, 3.2.4 Environment: JBoss 4.2.3, RHEL4, JDK1.5 Reporter: Dan Ciarniello According to the JPA, the allocationSize attribute to @TableGenerator is "The amount to increment by when allocating id numbers from the generator" but the value is actually incremented by 1 regardless of allocationSize. The id is generated properly apparently according to the formula id = lastkeyval*allocationSize + i where 0<i<allocationSize The problems with this algorithm are: 1. One cannot tell what the next key value range is from the key table without knowing the allocationSize (minor) 2. If the allocationSize is reduced, already existing key values will be generated (major) 3. If two applications are configured with different allocation sizes, there will be an overlap in generated values (major) -- 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
