We all know that compilation of large Scala codebases can be painfully slow,
Enter Bazel – an open source build tool from Google that allows for very fast build times while maintaining correctness and reproducibility.

In this talk I will share with you the story of how at Wix we have embraced Bazel and managed to dramatically improve our build times.
I will also talk about “Rules Scala” – the Scala plugin for Bazel that has cool features such as “unused deps” and “persistent workers” that help keep your build configurations correct and your Scala builds fast.
