Re: advice on failover setup

Don,

I neglected to mention the Solr Katta integration patch, SOLR-1395
That's a great place to start coding wise!

 If the latter (ZooKeeperIntegration and KattaIntegration are not available
 yet), is there any sort of guess as to when these features might become
 available?

 thanks,
 Don

 Dan,

 For automatic failover there are 2 wiki pages that may be helpful,
 however both are in the development stage.

  Hi folks,
 
  I'm tasked with designing a failover architecture for our new Solr
  server. I've read the Replication section in the docs
  (http://wiki.apache.org/solr/SolrReplication) and I need some
  clarification/insight. My questions:
 
  1.      Is there such a thing as master/master replication?
  2.      If we have one master and one slave server, and the master goes
  down, does the slave automatically become the master? What's the process
  for brining the server back up and getting the two back in sync? Is it a
  manual process always?
  3.      We're running Solr inside Tomcat on Windows currently. Any
  suggestions for a load balancer that will automatically switch to the
  alternate server if one goes down?
 
  Thanks in advance,

Don,

Sorry, yes the features are under development and also hopefully
the wikis as well. :)

When they become available, well I can say personally I need the
Katta integration working in the next few months. Jason Venner
got it working over at his company.  It might be good to
describe your use case to see what is a good fit for you.
