Implementing a Key-Value Store – Part 9: Data Format and Memory Management in KingDB

Published by Emmanuel Goossaert on August 3, 2015

This is Part 9 of the IKVS series, “Implementing a Key-Value Store”. You can also check the Table of Contents for other parts. In this series of articles, I describe the research and process through which I am implementing a key-value database, which I have named “KingDB”. The source code is available at http://kingdb.org. Please note that you do not need to read the previous parts to be able to follow. The previous parts were mostly exploratory, and starting with Part 8 is perfectly fine.

In this article, I explain how the storage engine of KingDB works, including details about the data format. I also cover how memory management is done through the use of a compaction process.

In the previous articles, I have laid out the research and discussion around what needs to be considered when implementing a new key-value store. In this article, I will present the architecture of KingDB, the key-value store of this article series that I have finally finished implementing.

This is Part 1 of the IKVS series, “Implementing a Key-Value Store”. You can also check the Table of Contents for other parts.

In this article, I will start with a short description of what key-value stores are. Then, I will explain the reasons behind this project, and finally I will expose the main goals for the key-value store that I am planning to implement. Here is the list of the things I will cover in this article:

1. A quick overview of key-value stores
2. Key-value stores versus relational databases
3. Why implement a key-value store
4. The plan
