One of the big features of Delta Lake on Databricks (over the open source Delta Lake at http://Delta.io) is the Optimize command, and with it the ability to Z-Order your data... but what does that actually do? Why would you use it?
In this week's AdvancingSpark, Simon takes us through Z-Ordering, what it is and how you can enjoy the benefits of Data Skipping!
For more info, and the Databricks demo notebook used first, see: https://docs.databricks.com/delta/opt...
