@ck7007 no worries. 

I asked a question on the other thread: https://community.databricks.com/t5/data-engineering/cost/td-p/130078 , I'm not sure if you're classing this thread as the duplicate or the other one so I'll repost.

I didn't see you mention anything around Liquid Clustering https://docs.databricks.com/aws/en/delta/clustering was there a particular reason why? It was meant to replace Z-ORDER, if you did, I'd love to hear about what impact it had for your use case.

All the best,
BS
