This is Part 4 of the IKVS series, “Implementing a Key-Value Store”. You can also check the Table of Contents for other parts.

I finally settled on a name for this whole key-value store project, which from now on will be referred as ~~FelixDB~~ KingDB.

In this article, I will take a look at the APIs of four key-value stores and database systems: LevelDB, Kyoto Cabinet, BerkekeyDB and SQLite3. For each major functionality in their APIs, I will compare the naming conventions and method prototypes, to balance the pros and cons and design the API for the key-value store I am currently developing, KingDB. This article will cover:

1. General principles for API design
2. Defining the functionalities for the public API of KingDB
3. Comparing the APIs of existing databases
    3.1 Opening and closing a database
    3.2 Reads and Writes
    3.3 Iteration
    3.4 Parametrization
    3.5 Error management
4. Conclusion
5. References

This is Part 3 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 walk through the architectures of Kyoto Cabinet and LevelDB, component by component. The goal, as stated in Part 2 of the IKVS series, is to get insights at how I should create the architecture my own key-value store by analyzing the architectures of existing key-value stores. This article will cover:

1. Intent and methodology of this architecture analysis
2. Overview of the Components of a Key-Value Store
3. Structural and conceptual analysis of Kyoto Cabinet and LevelDB
    3.1 Create a map of the code with Doxygen
    3.2 Overall architecture
    3.3 Interface
    3.4 Parametrization
    3.5 String
    3.6 Error Management
    3.7 Memory Management
    3.8 Data Storage
4. Code review
    4.1 Organization of declarations and definitions
    4.2 Naming
    4.3 Code duplication
