Hello,

As I know amazon s3 now free from eventual consistency. All regions now support read-after-write. This issue is mentioned in S3 FAQ https://aws.amazon.com/s3/faqs/

So maybe document section "Eventual consistency" is no need.

Regards,
Dung

This is a bit subtle, although the us-standard region has strengthened its consistency guarantees, but Amazon still exhibits eventual behavior in read-after-overwrite and read-after-write-after-read scenarios:

I document these guarantees but my data are out of date:
