Revision 1528405
> Property index: faster unique indexes using new storage strategy
> ----------------------------------------------------------------
>
> Key: OAK-1059
> URL: https://issues.apache.org/jira/browse/OAK-1059
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, query
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
>
> The property index now stores all entries for a key as a tree
> (ContentMirrorStoreStrategy). This is very good for non-unique indexes.
> However, for unique indexes such as the UUID index, this results in lots of
> nodes.
> To improve performance for UUID lookup and update, the (only) entry could be
> stored as a property (UniqueEntryStoreStrategy).
