Subject Re: Atomicity of commits in Solr Cloud?
Date Thu, 12 May 2016 17:26:59 GMT
I'm not a dev, but I would assume the following if I were concerned with
speed and atomicity

A.  A commit WILL be reflected in all appropriate shards / replicas in a
very short time.
          I believe Solr Cloud guarantees this, although the time frame
will be dependent on "B"
B. Network, processor, size, complexity of commit and indexing, and other
variables will have an affect on how fast it happens
C. It is possible that during the process of getting the data to all Solr
instances, a user could query at just the right moment and get "stale"
data, but that state will not last very long.

Others on this list may correct me... but that's my best understanding.
