Under the Hood: PostgreSQL Writes & Kubernetes that Scales Itself

We’re back with another edition of DevDay Hyderabad, where curious minds meet deep tech. If you love understanding how things really work behind the scenes, this one’s for you.

### 👨‍💻 Talk 1:

### What Lies Beneath PostgreSQL: The Mechanics of Writes, MVCC and VACUUM

Speaker: Rohan Reddy Alleti

Think an UPDATE just changes a row? Not in Postgres.

This talk goes under the hood to show what really happens when your app writes to PostgreSQL. You’ll get a clear understanding of how Postgres handles multiple versions of rows (MVCC), how dead rows pile up, why VACUUM is critical, and how it affects performance.

We’ll use real examples and tools like pageinspect to peek into what’s happening on disk. Learn how Postgres optimizes updates using HOT (Heap Only Tuples), what transaction wraparound is, and how to keep your indexes efficient.

Who should attend:

• Backend developers working with PostgreSQL
• Anyone curious about performance bottlenecks in databases
• Engineers who want to understand database internals better

Takeaways:
✅ Understand how MVCC and VACUUM work
✅ See what INSERTs/UPDATEs do under the hood
✅ Learn practical tips to avoid Postgres bloat and improve performance

### ☁️ Talk 2:

### Autoscaling on Autopilot: Let Kubernetes Do the Heavy Lifting

Speakers:

• Vighnesh Pathrikar
• Amit Bhagat

You’ve got your app running in Kubernetes. Great! But what happens when traffic spikes… or drops?

This session dives into how you can make your workloads scale automatically based on demand. Learn how tools like HPA (Horizontal Pod Autoscaler), VPA (Vertical Pod Autoscaler), KEDA (for event-driven scaling), and Cluster Autoscaler help you build a responsive, cost-effective setup—without micromanaging resources.

Expect:

• A hands-on demo
• Real-world tips from production
• Lessons learned from scaling the hard way

Who should attend:

• Developers, Architects and DevOps folks deploying apps on Kubernetes
• Engineers tired of manual scaling and YAML overload
• Anyone running cloud-native apps

Takeaways:
✅ Learn how to make your apps scale up and down smoothly
✅ Get familiar with HPA, VPA, KEDA & Cluster Autoscaler
✅ Walk away with a blueprint to autoscale your workloads
