I like how blazingdb helps me to quickly process my large datasets without any bottlenecks, it's very easy for use with python language as well! there are few things which i don't really love about this product; but nothing worth mentioning in such case so far everything has been great!! if you want something simple yet powerful then try out blazeldb. It easily solves most of our problems regarding processing huge amounts datapoints while keeping them secure from hackers attacks or even other users' accesses etc..
