Building Data Systems in 2025: Dark Secret Behind “S3 as Primary Storage"
Details
About
“S3 as Primary Storage” has become the mainstream architecture for modern data systems. From RisingWave to Chroma and WarpStream, a growing number of systems are adopting this model. But behind its scalability and simplicity lies a hidden cost—literally. S3 is notorious for its high latency and steep access fees, which can quickly spiral out of control in production.
In this webinar, Yingjun Wu from RisingWave (the leading stream processing system) and Hammad Bashir from Chroma (the leading vector database) will share how they’ve built cutting-edge data systems from the ground up using S3 as the foundation—and the real-world challenges they’ve faced while supporting large-scale, in-production workloads.
Speakers
Yingjun Wu -- Founder and CEO at RisingWave Labs
Hammad Bashir -- CTO at Chroma
