[jira] [Commented] (LUCENE-5680) Allow updating multiple DocValues fields atomically

["Robert Muir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-5680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14001244#comment-14001244 ] 

Robert Muir commented on LUCENE-5680:
-------------------------------------

I don't think DocValuesFieldUpdate should become public, nor should it become a parameter in IW's api.

I think whats wrong here is that these methods on indexwriter need to use Field api or something instead. this way the user just calls IW.update(new Term("id", "12345"), new NumericDocValuesField("xyz", 6)) and its similar to how they build a document initally versus a totally separate API.

> This has come up on the list (http://markmail.org/message/2wmpvksuwc5t57pg) -- it would be good if we can allow updating several doc-values fields, atomically. It will also improve/simplify our tests, where today we index two fields, e.g. the field itself and a control field. In some multi-threaded tests, since we cannot be sure which updates came through first, we limit the test such that each thread updates a different set of fields, otherwise they will collide and it will be hard to verify the index in the end.
> I was working on a patch and it looks pretty simple to do, will post a patch shortly.
