Copy-on-Write B‑Trees provide an elegant mechanism for fast, consistent snapshots, cutting write amplification and lock contention. This post explains the data structure, its snapshot workflow, and real‑world performance gains.
Learn how copy‑on‑write B‑trees work, why they make snapshots cheap, and what trade‑offs you should weigh when choosing this storage engine.
Copy‑on‑Write (CoW) lets Linux share pages until they’re modified, dramatically cutting memory footprints for forks, containers, and snapshots.
Copy on Write lets forked processes share memory pages until they modify them, slashing RAM demand and keeping applications responsive.
Copy‑on‑write lets multiple threads share the same memory until a write occurs, dramatically cutting duplication and boosting throughput in concurrent systems.
