Hi, I would like to run two Solr instances on different computers as a cluster. My main interest is High availability - meaning, in case one server crashes or is down there will be always another one.
(my performances on a single instance are great. I do not need to split the data to two servers.) Questions: 1. What is the best practice? Is it different than clustering for index splitting? Do I need Shards? 2. Do I need zoo keeper? 3. Is it a container based configuration (different for jetty and tomcat) 4, Do I need an external NLB for that ? 5. When one computer is up after crashing. how dows it updates its index?
