How to Handle One Million Transactions per Second on a Single CPU Core
In my couple of my last articles, I was talking about persistence with in-memory databases. Check this out here and here.
In this article, I would like to touch upon the performance problems of in-memory databases. For starters, let's just talk about performance in the simplest case: when you change the value of a specified key. And let's simplify this case even further: assume there's no database server at all — I mean no client-server interaction over the network. So, the database resides totally inside your application's RAM space.
