Solr is provides availability and it is tolerant to partioning so that leaves
consistency. It is eventual consistent.

Subject: Re: consistency in SolrCloud replication
I want to know where SolrCloud stands in terms of CAP.
SolrCloud is a CP system. In the face of partitions, SolrCloud favors
consistency over availability (mostly concerning writes). The system
is eventually consistent, but should become consistent with a pretty
low latency, unlike many cases
Thanks for the info, Mark. By a request won't return until it's affected
all replicas, are you referring to the update request or the query?

I'm talking about an update request. So if you make an update, when it
returns, your next search will see the update, because it will be on
all replicas. Another process that is searching rapidly may see an
eventually consistent view though (very briefly). We have some ideas
to make that view more
will not return unless all
replicas have completed their commits. Right?

It's included as soon as it has been indexed - though a request won't return
until it's affected all replicas. Low latency eventual consistency.
