Open Data Circle – Lakehouse Meetup #2
Overview
Open Data Circle – Lakehouse Meetup #2, co-hosted with CelerData, explores how modern data platforms are evolving toward an AI-native future — as AI-driven workloads reshape expectations for storage, indexing, and real-time analytics across table formats, compute engines, and retrieval-oriented applications.
This meetup examines these shifts from three complementary perspectives:
Architectural directions for making lakehouse systems AI-native
StarRocks as a next-generation high-performance engine for the AI era
Practical lessons from building RAG systems, including an AI Legal Reviewer demo
Expect concise, insight-driven sessions and opportunities to connect with peers shaping the next generation of data platforms.

Exploring AI-native Directions for Lakehouse
AI-native workloads are redefining expectations for lakehouse systems — requiring table formats and storage layers to support richer semantics, adaptive indexing, and tighter integration with real-time and vector-driven data.
This talk examines emerging approaches for making lakehouses more AI-native, with a focus on architectural shifts happening at the table-format and data-layout layers. By recognizing patterns emerging across modern open formats and storage designs, the session highlights how these developments are opening new possibilities for more adaptive, intelligent, and future-ready data platforms.

StarRocks: A Fast Data Engine for Rapid AI Development
With the rapid evolution of Large Language Models (LLMs) and AI Agents, data governance has become a core competitive differentiator for enterprises.
To meet the demanding requirements of modern AI applications, this session explores how CelerData has optimized the essential pillars of a Data Engine: real-time performance, compatibility, and scalability. We will demonstrate how StarRocks delivers a lightning-fast, unified lakehouse architecture, providing the robust data foundation necessary for the AI era.
