The 1:1 style meant the training was tailored to my individual needs.
Andy McGuigan
Course - Cassandra Administration
Topics approached. Very complete.
Carlos Eloi Barros
Course - Cassandra for Developers
Trainer had good practical knowledge about using Cassandra day-to-day at least for development purposes. Catering (snacks, coffee hour) were great 3 days length was good.
