Subject [jira] [Updated] (LUCENE-5680) Allow updating multiple DocValues fields atomically
Date Sun, 18 May 2014 12:43:37 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-5680?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shai Erera updated LUCENE-5680:
-------------------------------

    Attachment: LUCENE-5680.patch

I made a slight change to the reduce the API: instead of exposing the public Numeric/BinaryDVUpdate,
I added a factory DVUpdate.createNumeric/Binary. Otherwise, someone might confuse and think
that by extend DVU to e.g. SortedDVU, he can automagically update SortedDV fields. I also
changed DVUpdate ctor to private.

> 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.
