Data Reprocessing Pipeline in Asset Management Platform @Netflix

摘要

At Netflix, we built the asset management platform (AMP) as a centralized service to organize, store and discover the digital media assets created during the movie production. Studio applications use this service to store their media assets, which then goes through an asset cycle of schema validation, versioning, access control, sharing, triggering configured workflows like inspection, proxy generation etc. This platform has evolved from supporting studio applications to data science applications, machine-learning applications to discover the assets metadata, and build various data facts.

During this evolution, quite often we receive requests to update the existing assets metadata or add new metadata for the new features added. This pattern grows over time when we need to access and update the existing assets metadata. Hence we built the data pipeline that can be used to extract the existing assets metadata and process it specifically to each new use case. This framework allowed us to evolve and adapt the application to any unpredictable inevitable changes requested by our platform clients without any downtime. Production assets operations are performed in parallel with older data reprocessing without any service downtime. Some of the common supported data reprocessing use cases are listed below.
