Build Your Own Database From Scratch
Build Your Own Database From Scratch
Persistence, Indexing, Concurrency
About the Book
Databases are not black boxes. Understand them by building your own from scratch!
This book contains a walk-through of a minimal persistent database implementation.
The implementation is incremental. We start with a B-Tree, then add a new concept with each chapter, and eventually go from a simple KV to a mini relational DB.
Although the book is short and the implementation is minimal, it covers three important topics:
1. Persistence. How not to lose or corrupt your data. Recovering from a crash.
2. Indexing. Efficiently querying and manipulating your data. (B-tree).
3. Concurrency. How to handle multiple (large number of) clients. And transactions.
