> Automatically pick the latest active index version

> Key: OAK-8721
> URL: https://issues.apache.org/jira/browse/OAK-8721
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing, lucene
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Major
> Fix For: 1.20.0
>
>
> When using the composite node store for blue-green deployments, multiple
> versions of a index can exist at the same time, for a short period of time
> (while both blue and green are running at the same time). It is possible to
> select which index is active using the "useIfExists" settings in the index
> configurations. However, this is complicated and hard to explain / understand.
> Instead, we can rely on naming patterns of the index node name. E.g.
> * lucene
> * lucene-2 (newer product version)
> * lucene-2-custom-2 (customized version of lucene-2)
> * lucene-2-custom-3 (customized again)
> * lucene-3-custom-1 (newer product version)
> It would be good if index selection is automatic, meaning only indexes are
> active that are available in the read-only repository (of the composite node
> store).
