Where's the Elasticsearch topology/architecture diagram? I've heard many good things about Elasticsearch and it seems to be widely used for some time now, but what boggles me is that there is no simple conceptual diagram to be found on their website: http://ift.tt/lFHJOM. Well, at least not an easy to find kind of way. Sure there's some videos, but that's it?!
What I'm looking for is information on a few things:
1) What are 'master' and 'slave' concepts? What are the general terms to describe these concepts? I want to know so I can then further Google on these higher-level terms to understand analogous concepts in other distributed systems like Couchbase.
2) Does the client talk to a master node, and then is the master node in charge of routing the request to the proper shard in the cluster (possibly a different node)? Or is the hashing done on the client side and then talks to the proper node directly?
3) Can you explain to me a split-brain scenario in depth? How does this apply to other distributed systems like Couchbase? Or is it not applicable?
Thank you.
