Many development teams only realize the true cost of latency after their products have already gone live. This realization often comes too late, when users are already experiencing frustrating delays that drive them away from the application.What appears to be a simple AI Agent request on the surface actually involves a complex execution chain behind the scenes. Rather than a single model invocation, the system must orchestrate multiple sequential operations: the model first interprets the user's task, then calls various tools, reads from da...

Many development teams only realize the true cost of latency after their products have already launched into production environments.What appears to users as a simple AI Agent request often involves an elaborate chain of operations behind the scenes: the model interprets the task, invokes various tools, reads from databases, performs additional reasoning, calls external APIs, and finally generates the response. From the user's perspective, they see a single answer, but the system may have traversed back and forth between different services m...

The Hidden Dangers of Poor Sharding DesignIn the high-pressure environment of modern software development, few scenarios are more terrifying than a database system collapsing under its own weight. Picture this: it's 2 AM, the office lights are blazing like a holiday display, and your entire technical team is frantically trying to identify why the system is failing for the third time this month. The culprit? A sharding方案 that was once praised as "rock solid" has now become a ticking time bomb, detonating regularly and forcing the entire depar...
