# feature-store

A feature store is a centralized repository for storing, retrieving, managing, and sharing machine-learning features, while keeping feature computation consistent between model training and inference.

### AI overview

This article describes a prototype Feast offline-store plugin backed by Dolt, a version-controlled SQL database. It argues that Dolt's revision-based reads can provide point-in-time feature retrieval and reproducible training snapshots without the usual append-only log deduplication CTEs. Tests on toy datasets produced identical results with shorter queries, though the article presents this as an early spike rather than a production benchmark.

### Source excerpt

A weekend spike asked whether Dolt's AS OF reads could replace the ROW_NUMBER dedupe at the heart of every feature store's point-in-time join. Four weeks later, the RFC is quiet and the plugin's get_historical_features works end-to-end against a live Dolt server. Notes on building anyway.
