That's right but the patch can be adapted to use the default engine and use
"engine=${mysqlEngine}" only when engine property is set.
> in which case you'd have to specify a different engine in my.cnf.
This is a solution but i prefer to choose the engine when declaring the
PersistenceManager (because i may want to use the different default engine
everywhere else or i simply do not have the admin privilege to change this
setting in my.cnf).
> Choose the MySQL engine for database storage (default to MyISAM)

> Project: Jackrabbit Content Repository
> 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-2008-04-28.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.
