Seminar • Data Systems • The VAST Data Exascale AI Platform

Monday, November 24, 2025 10:30 am - 11:30 am EST (GMT -05:00)

Please note: This seminar will take place in DC 1302.

Vlad Zdornov, Lead, VAST Data R&D Center
Moshe Gabel, Senior Software Engineer
VAST Data

The VAST Data Platform (AI OS) is a unified platform for streaming, storing, querying, processing, enriching and indexing all types of structured and unstructured data. It is built on a novel disaggregated architecture (DASE), allowing it to scale to exabytes of capacity while maintaining exceptional performance, reliability and ease of operation. The VAST Data Platform comprises a multi-protocol all-Flash storage solution (VAST DataStore), a transactional, analytical and vector database coupled with an event streaming broker (VAST DataBase) and a pipeline orchestration infrastructure (VAST DataEngine).  VAST AI OS now powers some of the world's most demanding workloads: AI training, financial forecasting, high performance scientific computing (including the Nibi / SHARCNET cluster at UWaterloo), academic research, and more.

In the first part of this talk we will present the DASE architecture and the different platform components, and how they work together to address the needs of modern organizations and workloads. The second part of the talk will focus on the design and challenges of building the VAST DataBase: an LSM-based database with multi-version concurrency control that supports both analytical as well as vector workloads. Optimized for multi-PB sized tables with trillions of rows and vectors, the VAST DataBase provides high-performance during inserts, query and delete operations — with guaranteed transactional consistency, durability, isolation and availability. We will discuss some of the unique challenges caused by VAST Database's scale and unique DASE distributed architecture, which renders many common approaches infeasible.
