Description Horia Chiorean 2013-12-24 10:02:00 UTC

In a repository which has indexing enabled, when a node is being updated and only has property changes, the current code will reindex all the node's children.

This is a bug which, once fixed, should (significantly) improve performance in this scenario because the only case when after a node update the children of this node should be reindexed is when the path of the parent node has changed. In all other cases the children should never the "touched" .

Comment 1 Horia Chiorean 2014-01-03 07:13:25 UTC

This is a critical performance improvement which should be part of the first DV rollup patch.
