IT Professional, 27(4), 40-47. https://doi.org/10.1109/MITP.2025.3532129 --- This work was supported by national funds through FCT (Fundação para a Ciência e a Tecnologia), under the project - UIDB/04152/2020 (DOI: 10.54499/UIDB/04152/2020) - Centro de Investigação em Gestão de Informação (MagIC)/NOVA IMS).This article studies the significance of feature stores in machine learning (ML) operations frameworks, specifically examining how they affect processing times and overall workflow efficiency. Feature stores act as centralized storage locations for handling and providing features for ML models, thus guaranteeing uniformity and dependability throughout training and inference steps. We used the Freddie Mac Single-Family Loan-Level dataset to examine the differences in processing times when utilizing a feature store compared to not using one. The findings show that feature stores effectively improve ML processes by decreasing delays and boosting output, which is crucial for fast model development and prediction. Moreover, the article puts forward a structure for assessing the advantages of incorporating a feature store, considering elements like team size, feature intricacy, and the requirement for feature supervision as well as challenges such as the complexity of integration and infrastructure costs.8615356engMLOpsFeature StoreMachine LearningBig DataData ScienceData ManagementComplexity theoryMonitoringPredictive modelsReliabilityScalabilityStandardsThroughputTrainingWeb servicesSoftwareHardware and ArchitectureComputer Science ApplicationsSDG 9 - Industry, Innovation, and InfrastructureSDG 16 - Peace, Justice and Strong Institutionsjournal article10.1109/MITP.2025.3532129https://www.scopus.com/pages/publications/105013502879https://www.webofscience.com/wos/woscc/full-record/WOS:001554235800009
