An architecture note on running a Laminas cache layer on Memcached: one shared adapter, tenant-namespaced keys, a real health check, and explicit failure behavior.
When memcached evicts items unexpectedly, the root cause is often an unexamined slab class size or -f factor. This article maps the memory layout, operational checks, and failure modes so you can size cache with confidence.
Learn how to use McRouter to scale distributed Memcached clusters, prevent cache stampedes using leases, and implement consistent hashing for high-read workloads.
Choosing the right second‑level cache provider for NHibernate 5.x is critical for read‑heavy workloads. This guide compares SysCache, Redis, Memcached, and InMemory, explains trade‑offs, and walks through a concrete Redis implementation with validation steps.
Hit ratio falls, evictions rise, and free bytes still appear healthy? Slab-class fragmentation is usually the cause. This guide shows how to inspect per-class stats, identify the root, and apply targeted fixes.
A decision guide to adding a Memcached tier in front of MySQL, based on Facebook's published caching architecture: options compared, trade-offs, and a validation setup.
Learn how to identify and fix slab waste in Memcached by tuning growth factors and analyzing slab distribution to improve cache hit rates.
Learn how Memcached’s CAS operation prevents lost updates when multiple clients increment a shared counter, with a worked example, trade‑offs, and verification steps.
Learn how Memcached’s Check-And-Set operation lets multiple clients update the same key safely without external locks, with a worked example and practical limits.
