Talk 1: Building a Columnar Query Engine

In order to help our analysts fight spam on Pinterest, we built a column-oriented data store and query engine that scans events on the platform. Think BigQuery with the ability to take action on both past and future results. We'll talk about how we use BEAM to store billions of events and analyze them in real time.

About the Speaker

Preston Guillory is a software engineer on the Protect team at Pinterest. He works on infrastructure for fighting spam, fraud, and other forms of abuse that make the world a less pleasant place to be.

Talk 2: A Distributed Application for Force Scanning

Sparta's scanning software connects to force plates and reads information that is used to predict the risk of a sports injury and maximize performance. Their distributed application for creating force scans uses a main hosted Elixir/Phoenix web application together with hundreds of distributed laptops. Each of them is directly connected to a force plate, runs its own Elixir/Phoenix application, and "talks" to the main web application via Phoenix Channels. Channels are leveraged extensively to transmit live scan info, force data, and commands in real time. In this talk, Greg will describe the technical challenges of building and maintaining such a distributed application, along with the lessons learned.

Sparta has clients in the NFL, NBA, major league baseball, pro soccer, various university teams, the military, and also in medical applications.
