Solr and tunable consistency?

Hi,

Does someone know if Solr has a tunable consistency like the one found in
Cassandra or ElasticSearch
<https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html>
 ?

There is a replication_factor
<https://wiki.apache.org/solr/NewSolrCloudDesign> in Solr Cloud but it does
not seem to be providing tunable consistency.

Is there any other way to do the same in Solr?

Or any plans to add the same?


Thanks
SG

We have a minimum replication param on updates. IMO it's incomplete though.
I don't think it returns early yet, and instead of failing the request to
the user when the min replication is not achieved, it simply sets a flag.
