Vectstore, an AI search platform built on Rust, faced challenges with their initial setup using AWS RDS for relational data and Pinecone for vector search due to complexity, high latency, and rising costs. To address these issues, they switched to Neon, a serverless Postgres database with the pgvector extension, which allowed them to consolidate both relational and vector data into a single system. This transition resulted in reduced latency from 200ms to 80ms, simpler architecture, and a smoother developer experience across multiple regions. Neon's features such as branching, autoscaling, and native vector search support streamlined their operations, decreased infrastructure costs, and improved overall performance by enabling efficient management of multi-region deployments and spiky workloads.
