Show HN: Book to help you build a PostgreSQL-like database server from scratch

I just finished writing my book that guides you through building your own SQL database server from scratch.

The software engineering books I've enjoyed the most are the ones that let you learn through writing code and experimentation, which is why I wanted to create a practical book.

More details and a preview at https://technicaldeft.com/build-a-database-server

In summary:

+ Learn how parse and type check SQL

+ Execute complex queries that use JOIN and GROUP BY

+ Challenge yourself with suggested extensions

+ Comparisons with real databases including PostgreSQL, MySQL, SQLite and DuckDB

+ Pick a what language you want to build your implementation in

+ Test suite to help you build and refactor your project

You can use the code CREATE to get 20% off the price.
