Pinterest encountered a significant performance issue during the migration of its search infrastructure, Manas, to Kubernetes, where one in a million search requests experienced latency spikes. The investigation revealed that cAdvisor’s memory monitoring processes were causing excessive contention, leading to these delays. The team resolved the issue by disabling a specific metric in cAdvisor, allowing them to continue their migration efforts without compromising performance.

The article discusses a memory regression issue encountered during the development of a Go application, highlighting the steps taken to identify and resolve the problem. It emphasizes the importance of monitoring memory usage and provides insights into debugging techniques used to tackle the regression effectively.

Sharing a single Redis cache cluster across multiple services can lead to significant issues, such as key eviction affecting all services, complicating monitoring and debugging processes. While it may seem simpler initially, this approach can create confusion and performance problems as the system scales. In some cases, a shared cache is acceptable, but it's often better to maintain separate clusters for improved reliability and clarity.
