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.
