Centralized repository for storing, managing, and serving ML features with support for both batch and real-time retrieval. Enable feature reuse across teams and ensure consistency between training and inference.
Real-time fraud scoring features, credit risk indicators, transaction aggregations
User behavior features, product embeddings, recommendation signals
Driver/rider features, demand prediction signals, pricing inputs
Patient history features, clinical indicators, treatment outcome predictors
User profile features, ad performance metrics, targeting signals
Define feature schemas, data types, and transformations with clear documentation and ownership
Configure batch storage for historical features used in training data generation
Deploy low-latency storage for real-time feature serving during inference
Build automated pipelines for feature computation, materialization, and refresh
Integrate feature retrieval APIs into training and serving infrastructure
Set up feature freshness monitoring, drift detection, and access controls
