Why Write-Ahead Logging Outperforms Direct Disk Updates
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.
Optimizing Write Ahead Logs for High Throughput Databases
A deep dive into WAL optimization strategies that boost throughput while preserving data safety.
Why Copy-on-Write B-Trees Improve Database Concurrency Performance
This article explains how copy‑on‑write (COW) B‑trees work, why they improve concurrency, and what trade‑offs they introduce for modern database engines.
Why Copy-on-Write B-Trees Improve Database Concurrency Control
Copy-on-Write B‑Trees provide immutable snapshots for readers while writers work on new nodes, enabling high concurrency with minimal blocking.
