Description

Currently a CommonsHttpSolrServer can talk to only one server. This demands that the user have a LoadBalancer or do the roundrobin on their own. We must have a LBHttpSolrServer which must automatically do a Loadbalancing between multiple hosts. This can be backed by the CommonsHttpSolrServer

This can have the following other features

• Automatic failover
• Optionally take in a file /url containing the the urls of servers so that the server list can be automatically updated by periodically loading the config
• Support for adding removing servers during runtime
• Pluggable Loadbalancing mechanism. (round-robin, weighted round-robin, random etc)
• Pluggable Failover mechanisms
