S11 E28: The Temporal Correctness Crisis: Why Static RAG Context Leads to Broken AI Agent Actions and How to Engine-Unify Real-Time Streaming Data with Hojjat Jafarpour, Founder & CEO of DeltaStream
Dec 9, 2025 · Season 11 · Episode 28 · 22 min
Data streaming, without all the infastructure
Hojjat Jafarpour lives with his family in California. He got his PhD in databases and data streaming, back when the landscape was different and data streaming wasn't "cool" yet. He was an early member at Confluent, but also spent time at Quantcast, Informatica, and NEC Labs. Outside of tech, he has a family with young kids. He enjoys traveling, and can't wait until the kids are old enough to take on big trips.
Hojjat joined Confluent in their early days. He was on a project that built out kSQL, which was a key cornerstone of Confluent. As these were the early days of stream processing, he started to think about ways to make it easier - to make this sort of tech available without all the infrastructure.
This is the creation story of DeltaStream.
