angela commented on JCRVLT-105:
-------------------------------
[~cziegeler], the node type of a node can be changed since JCR 2.0 by calling
{{Node.setPrimaryType}}. IMO it should therefore even be possible with JCR API.
> Optimize package handling for Oak

> Vlt was written for Jackrabbit 2, I assume with Oak some operations can be
> optimized. We just stumpled across some code which changes the node type of a
> node on a package import: it basically does this by moving all child nodes to
> a temp node, deleting the node, recreating it with the new node type and then
> moving all child nodes back. If the tree below that node is large, this is a
> very heavy and expensive operation. Afaik, node type can be changed with Oak.
> There might be other optimizations like this
