Netflix’s revenue is mainly generated by users’ subscription fees (Kasula, 2020), and to keep customers from cancelling their access, the company relies heavily on the Netflix Recommender System (NRS) which combines big data analytics with powerful machine learning (ML) algorithms (Jackman & Reddy, 2020; Pajkovic, 2021) to keep users engaged and satisfied with the service.  The aim of the NRS is to offer a personalized experience and provide viewing recommendations to each customer (Pajkovic, 2021) based on preferences generated by their rating history (rating the titles they watch), Netflix’s requests for feedback, a “similarity” approach across subscribers, movies, genres, etc. (Kasula, 2020).

Kumar et al. (2021) explains that with big data, it is possible to store large volumes of data, but not in a conventional data setup. Conventional data reflects a centralized database architecture, and big data is found in distributed databases. The data sources are many when dealing with big data, but severely limited with co...
