Concurrency in DynamoDB : The Guide You Wish You Had Before Production

Concurrency in DynamoDB : The Guide You Wish You Had Before Production
Picture this: Multiple users hit „save” at the same time, and your DynamoDB data turns into a complete mess. Been there, done that!
When working with DynamoDB, one of the biggest challenges is ensuring data consistency when multiple sources update the same item simultaneously. In this practical session, I’ll show you how to tame the beast of concurrent updates using DynamoDB’s powerful features that many developers overlook.

You’ll learn:
✅ Why concurrent updates create data integrity problems
✅ How conditional writes prevent overwriting latest changes
✅ Implementing optimistic concurrency control with version numbers
✅ Using atomic counters for conflict-free updates
✅ When to leverage transactions for multi-item consistency

This is a beginner-friendly session. Even if you haven’t worked with DynamoDB yet, I guarantee you’ll walk away with valuable insights that will save you from painful data consistency issues down the road.
