- Jul 27, 2026 Shared Build Cache Design: Action Keys, Content Store, and Eviction Why a build cache is two stores with different lifetimes, how write-once content addressing enables deduplication, and which eviction and failure policies keep a cache outage harmless. devops
- Sep 12, 2025 Key Design and Eviction in External Session Stores How session records are keyed, sized, and expired in Redis and Memcached, and why an eviction policy can turn a memory shortage into a login outage. backend systems
- Jul 31, 2025 Storage Quota, Persistence, and Eviction Why a cache that was written successfully can be gone on the next visit, how best-effort and persistent buckets differ, and what estimate() does and does not tell an application about its budget. web platform
- Jul 30, 2025 Quota Accounting and Eviction Under Storage Pressure How browsers measure an origin's storage usage, where the quota figure comes from, what persistence changes, and how a victim is chosen when the disk fills. web platform
- Jul 17, 2025 TTL Expiry and the Two Ways an Entry Dies How deadline-based caching separates logical expiry from physical reclamation, why lazy and active expiry put the cost in different places, and how clocks and replicas make a TTL a bound rather than a promise. backend systems
- Apr 10, 2025 Why LRU Eviction Needs a Hash Map and a Linked List The data structure behind least-recently-used eviction, why exact recency ordering costs two pointers per entry, and what CLOCK and frequency-based policies give up to avoid that cost. backend systems
- Mar 17, 2025 Device Memory Oversubscription and Page Migration Selling more device memory than exists requires evicting pages to host memory, and the cost of that depends entirely on how the device detects and services a miss. gpu computing
- Feb 18, 2025 Storage Pressure: What a Device Does When the Disk Fills How the platform reclaims space from caches under pressure, why a nearly full flash volume slows down before it fails, and how an app should budget and shed data before the system does it. mobile computing
- Dec 18, 2024 Space-Based Architecture and the In-Memory Data Grid Removing the shared database removes the contention and makes memory the capacity limit. Replication windows, eviction, and write-behind persistence decide how much data loss the style concedes. software architecture
