For collections with this few nodes, 3 zookeepers are plenty. From what I've seen people don't go to 5 zookeepers until they have hundreds and hundreds of nodes.
100M docs can fit on 2 shards, I've actually seen many more. That said, if the docs are very large and/or the searchers are complex performance may not be what you need. Here's a long blog on testing a configuration to destruction to be _sure_ you can scale as you need: https://lucidworks.com/blog/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/ Best, Erick On Wed, Apr 13, 2016 at 6:47 AM, Jay Potharaju <jspothar...@gmail.com> wrote: > Hi, > > In my current setup I have about 30 million docs which will grow to 100 > million by the end of the year.
