Data Preprocessing And Feature Engineering Within Sql

via “transformation-based feature computation with sql and python”

Open-source ML feature store for training and serving.

Unique: Supports both SQL and Python transformations in a unified FeatureView abstraction, with automatic compilation to data warehouse SQL when possible (Spark, BigQuery) and fallback to Python UDFs for complex logic, enabling teams to write transformations once and execute them in the optimal environment

vs others: More integrated than separate dbt/SQL pipelines because transformations are co-located with feature definitions and automatically executed during materialization; more flexible than pure SQL solutions because it supports Python for complex logic
