Hacktoberfest Hack Day Bengaluru x OLake
- Sunday, 18 October 2026
- 10:00 AM – 9:00 PM IST
- OLake office, HSR Layout, Bengaluru
A one-day, in-person hackathon at the OLake office in HSR Layout, focused on open-source AI. Pick one of two paths at check-in and build it solo: Ask OLake, a chat assistant for the OLake docs, or OLake MCP, an MCP server that lets an AI agent operate OLake. Open to working professionals and university students.

Iceberg for Agents: Building AI-Ready Data Pipelines
AI agents fail in production because they're overwhelmed with data but starved for context. LLM models aren't the problem. The bottleneck is the data stack: fragmented silos, inconsistent definitions, and logic hidden in tribal knowledge. In this session, Andrew Madsen shows how Apache Iceberg becomes the backbone of AI-ready pipelines, elevating your implementation from a storage format to a live context layer that powers structured RAG, schema-aware agents, and autonomous reasoning.

From Source to Presto: Developer Playground for Fast Analytics
This talk introduces a lightweight developer playground that demonstrates how to ingest change data from a transactional database (like Postgres or MySQL), register it via an open-source REST catalog (e.g., Polaris or LakeKeeper), and instantly make it queryable in Presto. The demo will walk through the setup, tools, and real-time experience of how quickly one can go from source data to interactive Presto queries using open standards and pluggable components. Ideal for developers and data engineers exploring modern lakehouse and federated query patterns
