Installing Cassandra on Mac OS X

Caution!

Version Number might change!! The versions of all softwares mentioned here, including Cassandra will change as newer versions are launched.

Install Homebrew

Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:

Before starting please have a mongo replica set initiated. I have mongo running at localhost:27170 and elasticsearch at localhost:9200

The test dataset I used is available on the mongodb website.

I am using MongoDB 2.6 and Elasticsearch 2.2.0 on a Windows machine.

Here I have tested three cases:

• An index already exists, mc-test-index in this case

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
