Explore the architecture of Git's Content-Addressable Storage (CAS) and Directed Acyclic Graph (DAG) to understand how it ensures data integrity and efficient versioning.
Learn how Memcached's compare-and-swap (CAS) operation lets you safely update shared counters without lost updates, and see the trade‑offs involved.
State Management with Atoms Clojure Atoms utilize a Compare-And-Swap (CAS) mechanism to ensure thread-safe state transitions. The swap! function applies a transformation function to the current state and retries the operation if the state is modified by another thread before the commit completes.
