Why Log Structured Merge Trees Outperform B‑Trees for Writes
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.

How Copy‑On‑Write Optimization Reduces Database Memory Overhead
A deep dive into copy‑on‑write (COW) techniques shows how they cut database memory consumption, enable efficient snapshots, and boost concurrent workloads.
Why Copy on Write B-Trees Improve Database Concurrency
Copy‑on‑write B‑trees enable high‑concurrency database operations by allowing readers to see a stable snapshot while writers modify a new version of the tree. The article explains the underlying mechanics, performance benefits, and practical implementation tips.
Why Write-Ahead Logging Rescues Databases From Power Failures
Write-ahead logging (WAL) ensures that databases can survive sudden power loss by recording changes before they reach the data files, enabling rapid, loss‑free recovery.
Why LSM Trees Outperform B-Trees for Write Heavy Workloads
The article explains the fundamental design of LSM trees, contrasts them with B‑trees for write‑intensive scenarios, and outlines when each structure shines.
