The Developer Tools Podcast with Fexingo · 2026-07-23 · 9 min
Episode 128 of The Developer Tools Podcast explores why event sourcing - storing every state change as an immutable event log - is becoming the gold standard for auditability in modern APIs. Lucas and Luna break down how companies like Stripe and GitHub use event sourcing to generate complete, tamper-evident audit trails without the performance nightmares of traditional database triggers. They walk through a concrete example: a fintech startup that replaced a chaotic MySQL audit table with a Kafka-based event store, cutting audit query time from 90 seconds to under 200 milliseconds. The episode also covers the operational cost - storage grows fast, replaying events can be slow - and when you should just use append-only tables instead. If you're building APIs where compliance, debugging, or replay matters, this is the pattern to know. #EventSourcing #APIDesign #AuditTrail #Fintech #SoftwareEngineering #Kafka #Stripe #GitHub #Compliance #EventStore #APISecurity #DeveloperTools #FexingoBusiness #BusinessPodcast #TechPodcast #DevToolsPodcast #Infrastructure #SOXCompliance Keep every episode free: buymeacoffee.com/fexingo
