A full sample data import takes too long for the labs:

  • The example from the manual is 2010-2017 = 32m 31s
  • 2016-2017 = 12m23.285s minutes (more suitable for labs) (1.1GB)
  • 2017 only = 6m27.179s (600MB only)

We can possibly switch back to using the full data set after lightning becomes stable. The issue would still be DDL performance though.
