How Load Testing Exposes Database Connection Pool Leaks
from Software Testing with Fexingo: QA, Automation, and Reliable Software Engineering Hosted by Fexingo
Lucas and Luna dive into a specific failure pattern that plagues production systems: database connection pool leaks. They explain how connection pooling works, why leaks happen due to unclosed connections or improper timeout settings, and how targeted load testing can reveal these issues before they cause outages. Using a real-world example of a fintech startup that saw cascading failures during peak traffic, they walk through detection techniques like monitoring active vs idle connections, setting alerts on connection acquisition latency, and using tools like pgBouncer or HikariCP. They also discuss the importance of simulating realistic traffic patterns—not just brute-force requests—to catch gradual resource exhaustion. This episode is practical for engineers who want to build more resilient systems without over-engineering. #LoadTesting #DatabaseConnectionPool #ConnectionLeak #PerformanceTesting #CI_Pipeline #Fintech #PostgreSQL #HikariCP #pgBouncer #ResourceExhaustion #Observability #SoftwareTesting #QA #Automation #ResilientSystems #FexingoBusiness #BusinessPodcast #Technology Keep every episode free: buymeacoffee.com/fexingo
