[jira] [Created] (SOLR-9648) Wrap all solr merge policies with SolrMergePolicy

Keith Laban created SOLR-9648:
---------------------------------

             Summary: Wrap all solr merge policies with SolrMergePolicy
                 Key: SOLR-9648
                 URL: https://issues.apache.org/jira/browse/SOLR-9648
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Keith Laban


Wrap the entry point for all merge policies with a single entry point merge policy for more fine grained control over merging with minimal configuration. 

The main benefit will be to allow upgrading of segments on startup when lucene version changes. Ideally we can use the same approach for adding and removing of doc values when the schema changes and hopefully other index type changes such as Trie -> Point types, or even analyzer changes.
