MemcacheDB uses Memcached API, so you can use any client that you use to connect to Memcached.
I implemented...

Before going through the details, I want to tell about two tests I have written on the suite.
KeyValueCorrectness: Actually this is a straightforward test to check the correctness of a Key/Value DB or its binding. It writes and reads random values on random keys and asserts the equality of value that was written and read. This seems...

I have implemented a DB Testing Suite in Java, and its name is DBTestingSuite :).
I know that there are several DB benchmarking tools out there but I just wanted to implement my own tool that will help me on my further experiments. I’ve chosen Java as the language since it’s high-level :) and markedly fast with the latest major versions and JREs, and most DB brands have mature Java...
