HPA Tech Retreat: Take a Tour of the Netflix Media Database
Puri defined the Netflix Media Database as “a multi-tenant data store for dynamic temporarily and spatially varying metadata for Netflix media assets.” The database supports “audio, video, text, images, and also answers spatio-temporal queries on the media timeline.”
User features include “authentication and authorization; content vault (e.g., firewalls for pre-release content); Datastore-based access control; and high read throughput.” “Every Datastore has a schema,” said Puri. “The developer defines the schema, which is a schema-on-write system. Schema updates can be applied on the fly; are capable of representing spatial (3D) and temporal metadata; and integer units for temporal and spatial dimensions enable full precision.”
Puri also showed an architectural view of the system, whereby the Netflix Media Database is depicted as implementing its features via a suite of micro-services, each of which has a specific responsibility. Those micro-services include validation, persistence, indexing and query, all of which can be orchestrated through a temporal plate.
