Hello PGC,

Thanks for your feedback. Please find the answers to your questions below.

Q1

>> S3 Select allows you to filter data using SQL expressions. Because we’re only interested in retrieving data from a few specific columns, it’s easier and more suitable to use S3 Select over Athena. And, unlike Athena, we can do all of this without setting up a database.

Q2

>> I don’t quite agree with you here. Any =/ all. ‘Any’ could be a subset of data while ‘all’ means every available data. The scope of the per-query control limit spans each query made within a workgroup. Any queries could simply mean one or more queries running in a workgroup.

Q3

>> Thanks for pointing out our mistake here. We will revise this item.

Regards,

Carlo @ Tutorials Dojo
