Write-Ahead Logging (WAL) dramatically improves performance and durability by turning many small disk writes into sequential batches, while also simplifying crash recovery compared to direct updates.
LSM trees batch writes into immutable files, avoiding costly in‑place updates that B‑trees require. This post explains the mechanics behind their superior write performance.
A deep dive into copy‑on‑write (COW) techniques shows how they cut database memory consumption, enable efficient snapshots, and boost concurrent workloads.
Learn how Linux’s copy‑on‑write mechanism shares memory pages, cuts RAM consumption, and reduces page‑fault costs without sacrificing security.
Copy‑on‑write lets programs share data until it changes, cutting memory use and speeding up operations.
