Learn how Redis Lua scripts let you perform multi‑key operations atomically, with a step‑by‑step example, trade‑offs, and real‑world tips for developers. Avoid race conditions, reduce latency, and keep memory in check.
Stop premature Memcached evictions by tuning slab allocation. Learn how to identify internal fragmentation and align slab classes with your data payloads.
Learn how to use Apollo Client Type Policies to implement cache redirects, eliminating redundant network requests when moving from list views to detail views.
Learn how to leverage Jule's hardware-aligned data structures to eliminate cache misses and improve memory throughput in performance-critical applications.
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 to choose Memcached chunk size and growth factor to avoid premature evictions, reduce internal fragmentation, and validate slab health with stats slabs.
Optimizing Memcached Memory Distribution Memcached manages memory through a Slab Allocator to prevent fragmentation, grouping items of similar sizes into specific slabs. When a slab reaches capacity, the system triggers LRU eviction for that specific slab, regardless of whether memory is available in other slabs. To mitigate premature evictions and improve h
SERVER_ERROR out of memory in slab allocator Memcached's slab allocator divides memory into fixed-size chunks grouped into slab classes. Once a page is assigned to a specific slab class it cannot be reassigned to another class during the daemon's lifecycle. A shift in stored item sizes can exhaust one slab class while other classes retain free memory. In tha
