Feature Materialization From Batch Sources To Online Stores

Open-source ML feature store for training and serving.

Unique: Abstracts materialization across multiple compute engines (Spark, Kubernetes, local) and online stores (Redis, DynamoDB, PostgreSQL) via a unified Provider interface, allowing teams to swap backends without rewriting materialization logic

vs others: More flexible than cloud-native solutions (BigQuery Materialized Views, Snowflake Tasks) because it supports on-premises data warehouses and heterogeneous store combinations; simpler than custom Airflow DAGs because it handles schema inference and incremental updates automatically
