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.
A deep dive into WAL optimization strategies that boost throughput while preserving data safety.
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.
Copy-on-Write B‑Trees provide immutable snapshots for readers while writers work on new nodes, enabling high concurrency with minimal blocking.
This article explains how copy‑on‑write B‑trees work, why they speed up database snapshots, and what trade‑offs developers should consider.
