Maybe, but I'm not sure if Yehuda would want to take it upstream or
not. This limit is present because it's part of the S3 spec. For
larger objects you should use multi-part upload, which can get much
bigger.

Note that the multi-part upload has a lower limit of 4MiB per part, and the direct upload has an upper limit of 5GiB.
So you have to use both methods - direct upload for small files, and multi-part upload for big files.
Your best bet is to use the Amazon S3 libraries. They have functions that take care of it for you.
I'd like to see this mentioned in the Ceph documentation someplace. When I first encountered the issue, I couldn't find a limit in the RadosGW documentation anywhere. I only found the 5GiB limit in the Amazon API documentation, which lead me to test on RadosGW. Now that I know it was done to preserve Amazon compatibility, I don't want to override the value anymore.
