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.
