Inside Horizon: interactive analysis at cloud scale


Late last year, we were honored to be invited to talk at Reflections|Projections, ACM@UIUC’s annual student-run computing conference. We decided to bring a talk about Horizon, our system for doing aggregate analysis and filtering across very large amounts of data. The video of the talk was posted a few weeks back on the conference website.

Horizon started as research project / technology demonstrator built as part of Palantir’s Hack Week - a periodic innovation sprint that our engineering team uses to build brand new ideas from whole cloth. It was then used by the Center For Public Integrity in their Who’s Behind The Subprime Meltdown report. We produced a short video on the subject, Beyond the Cloud: Project Horizon, released on our Analysis. Subsequently, it was folded into our product offering, under the name Object Explorer.

In this hour-long talk, two of the engineers that built this technology tell the story of how Horizon came to be, how it works, and show a live demo of doing analysis on hundreds of millions of records in interactive time.
