***** Session Details *****

Speaker 1: Rajeet Kumar
Title: Stop Guessing, Start Indexing: A Developer’s Guide to Database Indexes

A lot of developers know that indexes make queries faster, but many don’t know why, when an index will actually be used, or why some queries ignore them completely.

In this talk, we open that black box.

We build a mental model of the B-Tree, the structure used by most databases for their default indexes, and look at its internal layout.

Using that model, we’ll explore where B-Tree indexes shine, where they fail, the costs associated with them, and how selectivity affects whether an index is used.

Finally, we’ll briefly look at practical techniques such as covering indexes and functional indexes.

Speaker 2: Jan Karremans
Title: Is your PostgreSQL truly Cloud(native)?
As organizations modernize their platforms with containers, Kubernetes, CI/CD pipelines, and microservices, databases are often the last piece to truly transform. Simply lifting and shifting PostgreSQL to a cloud VM does not automatically make it cloud-native. So what does?
We’ll cut through the buzzword bingo and examine what they mean for PostgreSQL in real-world environments. Drawing from decades of database experience and years running PostgreSQL in Kubernetes, this session highlights how cloud-native principles such as automation, resilience, observability, and rapid redeployment reshape the way developers and DBAs collaborate.
Whether you are a developer, DBA, architect, or decision-maker, this talk will help you assess where you stand today and what it takes to make PostgreSQL a true enabler of speed and innovation in modern cloud environments.
