Hi.
We currently using Quicksight on top of S3.
We are evaluating Snowflake, will have to be using the “Business Critical” tier?
I saw it here in the “Prerequisites”.
It makes the cost-benefit more complicated, and maybe need to leave Quicksight.
Any thoughts?
Hi,
I am using the cross account data source in different region using the VPC and Quicksight enterprise edition.
Both has no much cost as I expected during the my facility.
You can test it out for a week and AWS cost will give the real picture.
I my opinion, you must try it out. No much cost your will face.
