Athena charges for Glacier IR files

Question

If I have a 100 GB file saved in Glacier IR, will I be charged Retrieval fees for 100 GB when athena query this file? I have optimized the query in such a way that only 10 GB data is scanned. Will I be charged 10 GB or 100 GB towards Retrieval charges?

Answer

Hi,

Athena offers a pay-as-you-go pricing model and you are only charged for the amount of data scanned by each query. Additionally, you can get significant cost savings and performance gains by compressing, partitioning, or converting your data to a columnar format because each of those operations reduces the amount of data that Athena needs to scan to run a query.

Therefore, if you have compressed your original file of 100MB to just 10MB you will only be charged for 10MB since that is all that's being scanned.

You can also obtain price estimates with the AWS Pricing Calculator here: https://calculator.aws/#/addService

Hope this helps!
