[jira] [Created] (LUCENE-7659) IndexWriter should expose field names

Ishan Chattopadhyaya created LUCENE-7659:
--------------------------------------------

             Summary: IndexWriter should expose field names
                 Key: LUCENE-7659
                 URL: https://issues.apache.org/jira/browse/LUCENE-7659
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Ishan Chattopadhyaya


While working on SOLR-5944, I needed a way to know whether applying an update to a DV is possible (i.e. the DV exists or not), while deciding upon whether or not to apply the update as an in-place update or a regular full document update. This information is present at the IndexWriter in a FieldInfos instance, and can be exposed.
