Spotify are not moving to BigQuery alone. They are also using Dataproc, Google's managed Hadoop service (which co-incidentally went GA yesterday), which lets them get value out of all the orchestration tools they already use, like Luigi. (They are also adopting Cloud Dataflow, Cloud Pub/Sub and other parts of our Big Data stack.)
Spotify will be talking more about the specifics of their data pipelines at GCP Next in SF in March, - I would expect to see a lot more on the new Google Cloud Big Data blog at https://cloud.google.com/blog/big-data/ too.
Luigi has had BigQuery support for some time: https://github.com/spotify/luigi/pull/1002
