SOLR-10046: Add UninvertDocValuesMergePolicyFactory class. (Keith Laban,
Christine Poerschke)
> Create UninvertDocValuesMergePolicy
> -----------------------------------

> Key: SOLR-10046
> URL: https://issues.apache.org/jira/browse/SOLR-10046
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Keith Laban
> Assignee: Christine Poerschke
>
> Create a merge policy that can detect schema changes and use
> UninvertingReader to uninvert fields and write docvalues into merged segments
> when a field has docvalues enabled.
> The current behavior is to write null values in the merged segment which can
> lead to data integrity problems when sorting or faceting pending a full
> reindex.
> With this patch it would still be recommended to reindex when adding
> docvalues for performance reasons, as it not guarenteed all segments will be
> merged with docvalues turned on.
