Subject Re: Speculating about the removal of the standalone Solr mode

>From Alfresco's point of view this would be a bad thing. Alfresco uses Solr
in stand alone mode and has developed an entire sharding and replication
model that fit's the ECM use case. So being forced to have ZooKeeper and
Solr Cloud would not be ideal.
