Yonik Seeley commented on SOLR-5944:
------------------------------------

I was just chatting with Shalin while we were both at ApacheCon.  In addition to leader->replica reordering issues,
we also need to handle realtime-get in the single-node case.  The way to do this is just add the update to the tlog like normal (with some indication that it's a partial update and doesn't contain all the fields).   When /get is invoked and we find an update from the in-memory tlog map for that document, we need to go through the same logic as a soft commit (open a new realtime-searcher and clear the tlog map), and then use the realtime-searcher to get the latest document.

Oh, and _version_ will need to use DocValues so it can be updated at the same time of course.

> LUCENE-5189 introduced support for updates to numeric docvalues. It would be really nice to have Solr support this.
