Numeric DocValues Updates are not supported?

Hello,

Did I get this right - Numeric DocValues Updates (https://issues.apache.org/jira/browse/LUCENE-5189) have not supported yet in Elastic? It means that for Lucene document I can't update only DocValues column's value without affecting (recreating) this document?
If this is correct, does anyone have plans for the implementation of this support? Or there is strong concern against it?

That's correct, this is not currently supported in Elasticsearch

If this is correct, does anyone have plans for the implementation of this support? Or there is strong concern against it?

Right now there are no plans I'm aware of for implementing this. If you think this is something that would be worth adding I would recommend that you open an issue at https://github.com/elastic/elasticsearch/issues/ with as much detail as possible.
