Essential Suite — Artwork Producer Assistant
By: Hamid Shahid & Syed Haq
Introduction
Netflix continues to invest in content for a global audience with a diverse range of unique tastes and interests. Correspondingly, the member experience must also evolve to connect this global audience to the content that most appeals to each of them. Images that represent titles on Netflix (what we at Netflix call “ artwork” ) have proven to be one of the most effective ways to help our members discover the content they love to watch. We thus need to
AVIF for Next-Generation Image Coding
By Aditya Mavlankar, Jan De Cock¹, Cyril Concolato, Kyle Swanson, Anush Moorthy and Anne Aaron
TL; DR
We need an alternative to JPEG that a) is widely supported, b) has better compression efficiency and c) has a wider feature set. We believe AV1 Image File Format (AVIF) has the potential. Using the framework we have open sourced, AVIF compression efficiency can be seen at work and compared against a whole range of image codecs that came before it.

CDC is becoming increasingly popular for use cases that require keeping multiple heterogeneous datastores in sync (like MySQL and ElasticSearch) and addresses challenges that exist with traditional techniques like dual-writes and distributed transactions [3][4].
In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. As

Netflix Hack Day — Fall 2019
By Tom Richards , Carenina Garcia Motion , and Leslie Posada

Hack Day at Netflix is an opportunity to build and show off a feature, tool, or quirky app. The goal is simple: experiment with new ideas/technologies, engage with colleagues across different disciplines, and have fun!

Data scientists at Netflix relish our culture that empowers them to work autonomously and use their judgment to solve problems independently. We want our data scientists to be curious and take smart risks that have the potential for high business impact.

GraphQL Search Indexing
by Artem Shtatnov and Ravi Srinivas Ranganathan
Almost a year ago we described our learnings from adopting GraphQL on the Netflix Marketing Tech team. We have a lot more to share since then! There are plenty of existing resources describing how to express a search query in GraphQL and paginate the results. This post looks at the other side of search: how to index data and make it searchable. Specifically, how our team uses the relationships and schemas defined within GraphQL to automatically build and maintain a search database.
