How Graph Queries Transform Cloud‑Native Observability and Fault Diagnosis

In modern cloud‑native systems, treating each service, container, or middleware as an isolated entity hides the essential connections between components, so this article explains how integrating graph‑based data models and query languages like graph‑match and Cypher unlocks powerful fault‑impact analysis, topology insights, and performance‑optimized troubleshooting.

Analysis of Service Avalanche Caused by Misconfigured Jedis Parameters During Redis Cluster Master‑Slave Switch

A service‑wide avalanche occurred when a Redis 3.x master‑slave failover coincided with Jedis’ default 2‑second connection timeout and six retry attempts, causing up to 60‑second latencies; adjusting connectionTimeout, soTimeout to 100 ms and reducing maxAttempts to two limited latency to about one second and prevented cascade failures.

Kafka Cluster Fault Analysis: Root Cause and Cascading Failure Mechanism

A Kafka cluster at vivo suffered a total traffic drop across a resource group when a broker’s disk failed, because the default producer partitioner still hashed keys to the failed partition, exhausting client buffers and blocking all healthy partitions, prompting recommendations to avoid keys or use custom partitioners.

Why RocketMQ Took 10 Minutes to Recover: Deep Dive into a Production Outage

A production RocketMQ cluster suffered a 10‑minute message‑send timeout after a broker’s memory failure caused a server reboot, and the post analyzes the routing registration, name‑server removal logic, client‑side timeout handling, root cause of name‑server “dead‑lock”, and proposes deployment and code‑level fixes to prevent recurrence.
