Date Thu, 28 Feb 2008 11:07:51 GMT

     [ https://issues.apache.org/jira/browse/JCR-1435?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Sébastien Launay updated JCR-1435:
----------------------------------

    Attachment: jackrabbit-trunk-mysql-engine.patch
                jackrabbit-1.4.x-mysql-engine.patch

The patches for this issue in the 1.4 branch and the trunk:
- adding the mysqlEngine parameter for every MySQL aware database component
- rewriting all mysql.ddl with an extra engine=${mysqlEngine}
- add logging in debug level for seeing the SQL executed
- use MyISAM by default if the parameter is not set for backward compatibility

>             Project: Jackrabbit
>          Issue Type: Improvement
>          Components: jackrabbit-core
>    Affects Versions: core 1.4.1
>         Environment: MySQL with NDB Cluster engine
>            Reporter: Sébastien Launay
>         Attachments: jackrabbit-1.4.x-mysql-engine.patch, jackrabbit-trunk-mysql-engine.patch

> The MySQL scripts embedded into Jackrabbit does not specify the engine to use.
> So by default MyISAM is used and we cannot change this.
> But, depending on the environment we may want to use an alternate engine like
> InnoDB (for transaction support) or in my case NDB Cluster (for high availability).
> We can still manually created the tables and then set the wanted engine, but it would
> be better if there was a parameter for the engine for component in the repository.xml
> for automatic table creation.
