Inside DBs — Ricardo Jiménez-Peris

Notes on how databases actually work, one system at a time.

Each series here explores a topic in database internals through the architecture of real systems. The first focuses on FoundationDB — following a transaction from start to finish and using that path to explain how the system fits together.

FoundationDB separates transaction processing from storage. Rather than list its components, this post follows a single transaction through them, from the moment it starts to the moment its writes become readable.
