s3数据从互联网传输的价格是否包括读取文件内容的价格

Question

I have a web app with a download buttons to download objects from s3 buckets. I also have plot buttons to read the contents of csv files in s3 bucket using pandas read_csv to read the columns and make visualizations. I wanted to understand if the price for s3 data transfer out of the internet is only for actually download of files or it also includes just reading the contents too because the bytes are transferred over the internet in that case as well.

Answer 1

S3 does not operate like a file system. There is no notion of reading and writing portions of files as you would to a local or remote drive. To read a file you must always download the entire file and then read portions as needed. That is why AWS only shows pricing for data transfer.
