Sotetsu Suzugamine commented on HADOOP-18328:
---------------------------------------------
I share a web page that summarizes the S3 on Outposts specification in a
nutshell.
https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3OnOutpostsRestrictionsLimitations.html
Currently, storage classes are not implemented in S3A in such a way that they
can be changed, and all defaults are used, so they are not expected to be
affected.
The specifications for encryption are as follows.
> By default, all objects stored in the OUTPOSTS storage class are stored by
> using server-side encryption with Amazon S3 managed encryption keys (SSE-S3).
> You can also explicitly choose to store objects by using server-side
> encryption with customer-provided encryption keys (SSE-C).
Also, it is available with the same API as s3.
> S3A supports S3 on Outposts

> However, "s3-outposts.%s.amazonaws.com" is the preferred endpoint when
> accessing S3 on Outposts bucket by accesspoint.
> This ticket improves them.
