Buzzfeed Data Infrastructure with Walter Menendez - Episode 7


Buzzfeed needs to be able to understand how its users are interacting with the myriad articles, videos, etc. that they are posting. This lets them produce new content that will continue to be well-received. To surface the insights that they need to grow their business they need a robust data infrastructure to reliably capture all of those interactions. Walter Menendez is a data engineer on their infrastructure team and in this episode he describes how they manage data ingestion from a wide array of sources and create an interface for their data scientists to produce valuable conclusions.

Check out Linode at or use the code dataengineering2018 and get a $20 credit (that’s 4 months free!) to try out their fast and reliable Linux virtual servers. They’ve got lightning fast networking and SSD servers with plenty of power and storage to run whatever you want to experiment on.

GoCD is the on-premise open source continuous delivery server created by ThoughtWorks and modeled after the ideas in the Continuous Delivery book by Jez Humble and David Farley.

With GoCD’s comprehensive pipeline modeling, you can model complex workflows for multiple teams with ease. And GoCD’s Value Stream Map lets you track a change from commit to deploy at a glance.

GoCD’s real power is in the visibility it provides over your end-to-end workflow. So you get complete control of and visibility into your deployments, across multiple teams.

Say goodbye to deployment panic and hello to consistent, predictable deliveries.

To learn more about GoCD, visit for a free download. Professional Support and enterprise add-ons, including disaster recovery, are available.

      I apologize for that. Since the time that you posted this comment I have actually begun posting new episodes weekly, so that should at least help with getting a feel for the frequency. I will take a look at adding the post date to the content blocks as well.
