Re: [rules-users] drools - packaging creates a full snapshot...why?

I have been using drools for almost a year now and build several

it is because of all the workspace copies and the jcr overhead of them. I

why drools is doing (in RulesRepository):
this.session.getWorkspace().copy( source, newName );
The package snapshot is created only when you explicitly request Guvnor
to do so (through the "Create snapshot for deployment" button on package
editor). And it does not copy the whole work space, it only copies the
package to the snapshot area. You can always remove the package
snapshots if you do not needs them anymore.
its not like i need a copy, once the package is built, it doesn't
seem to
'rebuild it' from this snapshot. I have no way of "recovering to"
this
snapshot.
Package snapshot is a readonly copy (a snapshot) of a package at a
certain time, it serves as a simple version control mechanism for
packages. Start from Drools 5.3, package snapshot is not needed anymore
as we provide a much more powerful versioning support for packages based
on JCR versioning. Reverting a package will be possible, though this has
not been implemented yet (check
https://issues.jboss.org/browse/GUVNOR-1519).
Cheers,

Anyone can help me with the reason behind the copy (perhaps why I
shouldn't
just delete this copy? I'm sure there are side-effects of this I'm not
thinking of, etc., etc.,)
Any feedback is appreciated.
