Do you really need a Feature Store?

"Feature store" has been around for a few years. There are both open-source solutions (such as Feast and Hopsworks), and commercial offerings (such as Tecton, Hopsworks, Databricks Feature Store) for "feature store". There have been a lot of articles and blogs published around what "feature store" is, and why "feature store" is valuable. Some organizations have also already adopted "feature store" to be part of their ML applications. However, it is worthwhile to point out that "feature store" is another component added to your overall ML infrastructure, which requires extra investment and effort to both build and operate. Therefore it is necessary to truly understand and discuss "is Feature Store really necessary for every organization?".
