Previously I’ve wrote about key-value databases. They are awesome - ultra-fast, simple, can scale almost linear with the number of nodes. So why bother with complicating them?

Well, they have some issues.

The previous post laid out the most minimum requirements for something to be called a database. While they may be too bare bones for many, there are a lot of databases that don’t fulfill even half of them, and this isn’t stopping from using them on a daily basis.

The last time I’ve looked at files, this time something a bit more complex - key-value databases.

The world of databases is a fascinating topic. It is very diverse. Many of them are extremely complex systems, but there are also very simple ones. There are the general purpose ones, and ones that do only one thing good, but they do it excelent. Despite all of this we tend to pick them just like we order food in a restaurant:

In most cases .NET manages to solve the DLL hell problem pretty well, but sometimes it all falls apart, and when it does in best case scenario we see something like this:

Could not load file or assembly 'XXXX, Version=X.Y.Z.W, Culture=neutral, PublicKeyToken=eb42632606e9261f' or one of its dependencies. 
The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The much worst case is this:

The method 'XXXX' was not found on the interface/type 'YYYY, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null'.

This post is an analysis of why this happens and how to diagnose it:
