Abstract
AI agents have compressed business decisions from minutes to seconds. Data systems need to keep up.
This talk shows how to turn Kafka streams and Flink materialized views into a millisecond-latency query layer: a StreamHouse where streaming computation and serving state are designed together.
We’ll walk through the architecture behind Lightning Table and the practical techniques that make it fast: treating Kafka as the durable source of truth, making serving state recomputable, standardizing state layout for predictable queries, and separating hot, warm, and historical data.
The focus is on the engineering trade-offs, performance patterns, and failure modes practitioners need to consider when building real-time data systems for the agentic era.

Especially in Python, the UDF performance can be a dumpster fire. 11:45 Seacliff ABC Session Data Infrastructure Building a Data Platform with AI Mouli Mukherjee Engineering Manager @OpenAI Data platform sits at the intersection of infrastructure, governance, operations, and user experience. 13:35 Seacliff ABC Session One Does Not Simply Add Synchronous Writes - Bridging Batch and Real Time with Apache Iceberg Paige Elinson Staff Software Engineer @Datadog What happens when a batch ingestion platform needs to behave like an operational database? Datadog’s Reference Tables product was designed for asynchronous uploads of large datasets, but customers increasingly needed synchronous row-level edits, without sacrificing batch scale. 14:45 Seacliff ABC Session Building a StreamHouse: Turning Kafka Streams into a Millisecond Query Layer AI agents have compressed business decisions from minutes to seconds.
