Vexless — Serverless Vector Data Management

Overview

Vexless is a serverless vector data management system introduced at SIGMOD 2024, leveraging cloud functions for elastic and cost-effective vector similarity search.

Architecture

• Serverless Design: Built on cloud functions for auto-scaling
• Compute-Storage Decoupling: Separate compute and storage layers for cost efficiency
• Pay-Per-Use Pricing Model: Scales to zero when idle
• Stateless Workers: Compute nodes are stateless, enabling rapid scale-out

Publication

• Venue: SIGMOD 2024
• Authors: Su et al.

Use Cases

• Variable workloads with unpredictable query patterns
• Cost-sensitive vector search applications
• Prototyping and development environments
