New York Lakehouse OSS (Iceberg, Arrow, Polaris) Panel

This panel brings together core contributors and ecosystem builders behind Apache Arrow, Apache Iceberg, and Apache Polaris to unpack how open source standards are shaping the future of the lakehouse. You’ll hear how Arrow is becoming the de facto in-memory and transport layer for modern analytics, why Iceberg is the table format of choice for open lakehouses, and how Polaris is emerging as a unified catalog and governance layer for interoperable, multi-engine architectures. The panel digs into what’s landed recently—Arrow’s variant and geospatial support, Iceberg v3 features like deletion vectors and new data types, and Polaris 1.0 hardening and expanded object storage support—along with what’s coming next around V4, catalog standards, and richer indexing and security.

The discussion also gets practical: panelists explore where the “rough edges” still are in real-world deployments, from small files and streaming workloads to RBAC, credential vending, and truly portable governance across clouds and engines. If you’re investing in an open lakehouse stack or building AI and BI workloads on open formats, this conversation will help you understand how Arrow, Iceberg, and Polaris fit together, where the communities are headed, and how to future-proof your architecture on open standards.
