Yet, it can be a bit clunky to use and navigate. Here are 4 Apache Atlas alternatives to consider while researching for an open source data catalog tool that is best suited to your organizational needs.

4 open source Apache Atlas alternatives

  1. Lyft's Amundsen
  2. LinkedIn's DataHub
  3. Netflix's Metacat
  4. Uber's Databook

It was introduced to the world in April 2019 and open sourced later that year for adoption outside Lyft. It was primarily built to improve the productivity of data scientists, engineers, and analysts at Lyft.

Amundsen enjoys high adoption at Lyft and has an open source community spanning 750+ members, and 37+ organizations who are officially using it.

Typical use cases of Amundsen include:

  • Simple text search powering easy data discovery

Databook is Uber's open source data catalog tool that was first developed in 2016 when their data had not reached the current scale. It was later revamped to suit their evolving needs.

Uber is known to support more than 400,000 queries a day on its infrastructure. Most of those with zero engineering dependencies. Databook has made that possible.

Its main capabilities include:

  • Easy to add new metadata, storage, and entities
  • Services can access metadata programmatically
  • It can support an enormous volume of queries
  • Cross-data centre read and write

Databook Overview

Deploying a data catalog software that enables teams to discover, understand and use data is often the first step in enabling a collaborative and efficient data culture in your organization. But reaching their means answering multiple questions at once.

Should we build it? Should we buy it? Will it support all our primary use cases? Will the platform work in case we change our data stack in a couple of years? Will all our users be comfortable using it? How do we make a case for the money that we're asking for?

We understand this can be a bit overwhelming and it always helps to think through your options out loud. Let us help!

It would take six or seven people up to two years to build what Atlan gave us out of the box. We needed a solution on day zero, not in a year or two.
