Hacktoberfest Hack Day Bengaluru x OLake

Event Description
Hacktoberfest Hack Day Bengaluru x OLake is a one-day, in-person hackathon at the OLake office in HSR Layout, focused on open-source AI.

Registration link: https://events.mlh.com/events/15468-hacktoberfest-hack-day-bengaluru-x-olake

The Challenge: Ask OLake
OLake is an open-source data platform with two parts:

• OLake ingestion copies data from databases and streams (Postgres, MySQL, MongoDB, Oracle, MSSQL, DB2, Kafka, S3) into Apache Iceberg or Parquet.
• OLake Fusion keeps those Iceberg tables healthy with automated maintenance such as compaction.

Build a chat assistant for the OLake docs that answers user questions about both: setup, source configuration, sync modes, catalogs, table maintenance, deployment and troubleshooting.
Use the OLake docs and the open-source repos (olake, olake-ui, olake-helm, olake-fusion). Bring in outside sources when the docs aren't enough. Every answer must cite its sources and say clearly when it doesn't know.
It will run on a public website, so build it as if it's going to production.

Format
Individual hackathon, 4 hours, in person
Open to working professionals, students, anyone who can code really.
LLM API credits provided

What to submit (by 6:30 PM)

1. A publicly reachable endpoint: POST /ask with {"question": "..."} returning {"answer": "...", "sources": ["", ...]}
2. A chat UI that can be embedded in a docs site
3. Your repo, with a README explaining your architecture and design choices
