Amundsen – Lyft’s data discovery and metadata engine

Amundsen — Lyft’s data discovery metadata engine
In order to increase productivity of data scientists and research scientists at Lyft, we developed a data discovery application built on top of a metadata engine. A good way of doing so is
Existence and other fundamental metadata (like name and description of table and fields, owners, last updated, etc.)

This metadata is made available to everyone whether or not you have access to the data or not. Richer metadata (like column stats, preview)
This metadata is only available to users who have access to the data.
