> Reduce lookup for oak:index node under each changed node

> Key: OAK-5511
> URL: https://issues.apache.org/jira/browse/OAK-5511
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing
> Reporter: Chetan Mehrotra
> Labels: performance
> Fix For: 1.8
>
>
> Currently {{IndexUpdate}} does a lookup for {{oak:index}} node under each
> changed node. This is done to pickup index definitions and create IndexEditor
> based on those so as to index content under that subtree.
> This lookup results in extra remote calls on DocumentNodeStore based setup as
> for non leaf nodes NodeStore has to check from remote storage to determine if
> {{oak:index}} node is present or not.
> This lookup can be avoided by
> # Having an {{Editor}} which adds a hidden property {{:oak-index-present}} in
> parent node upon addition of {{oak:index}} as a child node
> # IndexUpdate would then does a lookup for {{oak:index}} node only if such a
> hidden property is found
> For upgrade we would have some logic which would make use of Nodetype index
> to identify all such nodes and mark them
