Learn how to choose between Memory, Filesystem, and Redis adapters in Zend/Laminas to optimize performance and avoid cache fragmentation in distributed environments.
Explore how Twitter's fan-out architecture optimizes read latency by shifting the computational burden from the reader to the writer, and how a hybrid model handles the 'celebrity' scale problem.
Design a distributed semaphore using Redis and Lua scripts to enforce a global concurrency limit across microservices. The article covers requirements, minimal design, trust boundaries, operational checks, failure modes, and when to adjust the architecture.
Learn how to use Redis Pub/Sub for real-time signaling. Understand the fire-and-forget mechanism, the subscriber state, and why it differs from message queues.
Compare suitability, operational responsibilities and limits before choosing this technology for a project. Which trade-offs should guide the decision?
When utilizing the laminas-cache component with a Redis backend, latency spikes occur during high-concurrency invalidation events. While the adapter provides a unified interface for tagging, the implementation of clearByTag lacks inherent atomicity across distributed nodes. In a high-load environment, multiple processes may trigger tag-based invalidations si
The same project needs to behave consistently on developer machines, in CI and after deployment. Which versions, dependencies and configuration should be recorded?
Least-Privilege Scope with Redis ACLs Redis 6.0 and later support Access Control Lists that restrict a user to specific key patterns with the ~ prefix alongside granular command permissions. When designing a least-privilege account, I want to confine an application user to a single namespace such as ~cache:* while still allowing ordinary read and write comma
Application performance is one of the main reason of using cache over relational database. Because it stores data in memory in the form of key value pair, we can store frequently accessed data in cache which are not changes very frequently. Reading from cache is much faster than database. Redis is one of the best solution in distributed cache market. I was d
