VAST DataBase delivers ACID compliance for mission-critical operations while enabling instant analytics on the same data— all with zero-maintenance operations.
Transactional & Analytical Support
Combine transactional consistency with analytical speed. VAST DataBase provides ACID reliability and flash-native performance, unifying transactions and analytics on one platform without compromise or data movement.
Database Architecture for Mixed Workloads
Break the Trade Off
Suited for High-Performance Queries and Transactions
The VAST DataBase combines transactional integrity with analytical scale, supporting fast updates and complex queries on the same platform. Newly written data lands instantly in persistent memory, then converts into optimized columnar chunks for high-speed analytics. Unlike traditional architectures that force a tradeoff between real-time operations and large-scale analysis, VAST processes data continuously—so insights, dashboards, and applications always reflect the most current information.
Transactional at Scale
Deep Write Buffers Eliminate Performance Trade-offs
Storage Class Memory (SCM) acts as a "shock absorber" while background processes transform row-based writes into optimized 32KB columnar chunks on an all-flash architecture. This removes traditional OLTP vs. OLAP compromises, delivering both transactional speed and analytical performance.
Linear Scaling Without Sharding
Built on VAST’s DASE architecture, all compute nodes (CNodes) can directly access every data node (DNode). This eliminates the need for sharding or partitioning, so performance scales linearly as nodes are added. Each new CNode instantly contributes transaction and query capacity—no rebalancing, coordination, or data redistribution required.
Optimized for Analytics
Intelligent Row-to-Columnar Migration
Data enters as row-based writes into Storage Class Memory buffers and is automatically transformed into columnar format on all flash in the background. This dual-stage design combines transactional write speed with analytical read performance, breaking the traditional tradeoff between real-time operations and large-scale analytics.
World’s Fastest Analytics on Flash
VAST DataBase consistently outperforms legacy and cloud object-based systems, delivering up to 20× faster query performance on highly selective workloads while using up to 90% less CPU. Its flash-native DASE architecture eliminates staging and rebalancing delays, delivering sub-second responsiveness on live data—even at exabyte scale. The result: real-time analytics performance once thought impossible on object storage.
ACID Compliant
Storage Class Memory for Instant Durability
VAST achieves ACID compliance through Storage Class Memory (SCM) write buffers that instantly persist transactions with extremely low latency. Unlike traditional systems that risk data loss during failures, SCM ensures durability from the moment transactions are committed, providing the foundation for reliable ACID properties at any scale.
Atomic Operations Across Tables
VAST supports atomic updates within and across multiple tables, treating complex multi-step operations as single, indivisible units. If any part of a transaction fails, the entire operation rolls back, maintaining database integrity. This eliminates data corruption risks common in distributed systems handling concurrent operations.
Self-Maintaining
No Partitioning or Sharding Required
Every compute node accesses the entire global dataset directly, removing the need to split indexes or tune partitions as data grows. This "low config" approach means no complex optimizations or rebalancing.
Write-in-Free-Space Eliminates Compaction
Updates create new 32KB columnar chunks with metadata links rather than rewriting entire files, while deletions use logical tombstoning. This eliminates the "small files problem" that plagues object storage systems and removes the need for resource-intensive compaction or vacuuming operations that disrupt production workloads.
