Debugging Scaling Issues
Explore techniques to detect and resolve software scaling issues by examining input rates, resource usage, and system metrics. Learn to identify bottlenecks using distributed tracing and performance data to diagnose high latencies and resource overloads effectively.
We'll cover the following...
Identify scaling issues
Based on the software system, its use cases, runtime environments, etc., there could be many ways to inundate it with input size and rate. So, scaling issues could affect a program’s behavior in many ways, and its symptoms could also as varied. We have already learned how a large input size affects the program’s runtime, consider the following scenarios:
Imagine if a process is being bombarded with requests, the rate of incoming requests is more than the rate at which it can process them because of resource constraints. So, the time taken to process the request could spike enormously, leading to high latencies. Sometimes, this delay could be so significant that it could look as if the program is stuck or hung. However, this is not a hang and the process would eventually recover by itself if the requests stop at some point and the program catches up. But, if the requests keep piling up for a long time, it could very well lead to the user suspecting as much. ...
