This article explains how Redis handles key expiration, the TTL and TTI concepts, periodic and lazy deletion strategies, their impact on persistence and replication, and the various memory eviction policies—including LRU and LFU—so developers can efficiently manage data and improve system performance.
Integrating structured knowledge graphs with generative AI provides traceable, explainable, and high‑precision reasoning across domains such as medicine, finance, and law, through techniques like Retrieval‑Augmented Generation, graph neural networks, and adaptive planning, dramatically reducing hallucinations and boosting expert‑level performance.
Redis 8.0, released on May 1, 2025, introduces a major license shift to AGPLv3, eight new native data structures—including vector sets, JSON, and time‑series—alongside a rebuilt query engine that delivers up to 16‑fold performance gains, enhanced security, and cloud‑native capabilities.
This article walks through seven essential RocketMQ concepts—including message ordering, delayed delivery, accumulation handling, transactional guarantees, retry mechanisms, storage strategies, and filtering—providing code examples, configuration tips, and visual diagrams to help developers build robust distributed messaging systems.
RocketMQ tackles the high‑performance, high‑reliability challenges of distributed messaging by combining sequential disk writes, memory caching, and multi‑level indexing, detailing its storage logic, core structures, zero‑copy techniques, replication modes, static topic scaling, and practical tuning guidelines for optimal throughput.
This article explains why and how to shard a MySQL database, covering vertical and horizontal partitioning, distributed transaction handling, unique ID generation, a real‑world e‑commerce case study, and future considerations for distributed architectures.
This article explains the concepts, implementation details, configuration steps, typical use cases, performance and security best practices, and future trends of Istio traffic mirroring for safe and controllable traffic replication in cloud‑native environments.
This article deeply explores Apache RocketMQ's retry mechanisms, detailing producer and consumer retry strategies, flow control handling, dead‑letter queue management, advanced configurations, best practices, and comparisons with Kafka and RabbitMQ, providing practical code examples and monitoring recommendations for building highly reliable distributed systems.
This article introduces Eino, an open‑source Golang framework for large‑model AI applications, explains its core capabilities, walks through creating a simple AI assistant with message templates and chat model integration, and demonstrates how to extend the system with tools and a modular architecture for future expansion.
The article explains how message backlog arises when producers outpace consumers in systems like Kafka or RocketMQ, outlines primary causes such as unexpected production spikes, broker failures, and consumer bottlenecks, and provides step‑by‑step mitigation strategies including capacity scaling, temporary queues, and optimization techniques for producers, brokers, and consumers.
