Copy‑on‑write B‑trees let databases capture point‑in‑time snapshots without blocking writers, enabling true atomic reads and fast recovery.
Copy‑on‑write B‑trees let databases take point‑in‑time snapshots instantly, without blocking writes. This post explains the mechanics, trade‑offs, and real‑world implementations.
Write-ahead logging (WAL) writes changes to a durable log before modifying the database, allowing recovery after crashes and eliminating corruption.

A deep dive into the structural differences that make B‑trees superior for read‑intensive scenarios, backed by benchmarks and real‑world engineering insights.
