Copy-on-Write B‑Trees provide immutable snapshots for readers while writers work on new nodes, enabling high concurrency with minimal blocking.
Copy‑on‑write lets the kernel clone a process without copying its memory pages, deferring duplication until a write occurs, which dramatically speeds up fork.
A deep dive into LSM‑tree internals, compaction strategies, and configuration knobs that let you squeeze maximum write performance from modern storage engines.
This article explains how copy‑on‑write B‑trees work, why they speed up database snapshots, and what trade‑offs developers should consider.
