cl-memcached

What problem does it solve?

This Skill enables Lisp developers to integrate memcached caching into their applications, reducing database load and speeding up responses in data-heavy workflows.

Core Features & Use Cases

• TEXT and META protocol support: provides both classic and modern memcached interactions for storage, retrieval, deletion, and advanced operations.
• Connection pooling: leverages pooled connections to deliver high throughput in concurrent environments.
• Atomic counters & CAS: supports mc-incr/mc-decr and CAS-based updates for safe, race-free data modifications.
• Batch operations & pipelining: enables bulk gets and pipelined writes to minimize network round-trips and improve latency.
• Usage patterns: covers cache-aside, expiration semantics, graceful cache-failure handling, and write-through strategies.

Quick Start

1. Load cl-memcached via Quicklisp: (ql:quickload :cl-memcached)
2. Create a default memcache: (defvar mem (cl-memcached:make-memcache :host "127.0.0.1" :port 11211))
3. Store a value: (cl-memcached:mc-set "greeting" "Hello")
4. Retrieve a value: (cl-memcached:mc-get-value "greeting")
5. Optional: enable pooling for better performance: (setf cl-memcached:mc-use-pool t)
