Save / backup Athena view
From AWS documentation, i can see that one of the main differences between Athena views vs Athena CTAS tables is that views don't actually contain or write any data. If a customer wants to persist / back up a view, is the best practice to have them create a CTAS so the data is persisted in S3? Or something else? Thanks!

Hi ,
A View in SQL is a logical object and by design is ephemeral.
If the customer requirements is to have a persistent copy of the view they should use a CTAS.
If their goal is actually to save the query result (running on that view or even on a table) they can follow the instructions in this documents (to backup the full view they could run a Select * from View):

hope this helps
