Hi everyone,

We have been using Solr Cloud (4.4) for ~ 6 months now. Functionally its 
excellent but we have suffered several issues which always seem quite 
problematic to resolve.

I was wondering if anyone in the community can recommend good resources / 
reading for setting up a highly scalable / highly reliable cluster. A lot of 
what I see in the solr documentation is aimed at small setups or is quite 
sparse.

Dealing with topics like:

*         Capacity planning

*         Losing nodes

*         Voting panic

*         Recovery failure

*         Replication factors

*         Elasticity / Auto scaling / Scaling recipes

*         Exhibitor

*         Container configuration, concurrency limits, packet drop tuning

*         Increasing capacity without downtime

*         Scalable approaches to full indexing hundreds of millions of documents

*         External health check vs CloudSolrServer

*         Separate vs local zookeeper

*         Benchmarks


Sorry, I know that's a lot to ask heh. We are going to run a project for a 
month or so soon where we re-write all our run books and do deeper testing on 
various failure scenarios and the above but any starting point would be much 
appreciated.

Thanks all,
Darren
