Tutorials on phantom and Cassandra

Issues and questions

back to top

We love Cassandra to bits and use it in every bit of our stack. phantom makes it super trivial for Scala users to embrace Cassandra.

Cassandra is highly scalable and it is by far the most powerful database technology available, open source or otherwise.

Phantom is built on top of the Datastax Java Driver, which does most of the heavy lifting.

We are very happy to help implement missing features in phantom, answer questions about phantom, and occasionally help you out with Cassandra questions! Please use GitHub for any issues or bug reports.


Some of the companies using phantom:

License and copyright

Phantom is freeware software and uses a proprietary license that in plain English says the following:

  • Phantom is the intellectual property of Outworkers, it is not provided under an OSS license.

  • You can use phantom in commercial products or otherwise, so long as you use one of the official versions available on Bintray or Maven Central.

  • You are not allowed to distribute altered copies of phantom in binary form.

  • You cannot offer paid for training on phantom unless you are a direct partner to Outworkers and you have a written intellectual property agreement in place with us.

  • If you simply have a Build.scala or build.sbt dependency on phantom, you have nothing to worry about.

  • All paid for features are published and sold separately as phantom-pro, everything that is currently available for free will remain so forever.

If you would like our help with any new content or initiatives, we’d love to hear about it!

Phantom was developed at outworkers as an in-house project. All Cassandra integration at outworkers goes through phantom, and nowadays it’s safe to say most Scala/Cassandra users in the world rely on phantom.
