Thanks for the PR @dyvol777. Can you please sign the CLA if you haven't already done so? And can you also update the changelog?

[dyvol777]

I'm sorry, but i didn't find any info in repo on how to sign the CLA. Can you give me a bit information about it?
And for changelog, i should add it for 1.6.0 or 1.5.1?

Hi,
The CLA is linked in the PR description: https://cla.datastax.com/

The changelog should be the 1.6.0 since this isn't a bug fix and will ship in our next minor release.

Thanks!

@dyvol777, quick question: wouldn't s3_compatible work for using CEPH RGW as backend?

[dyvol777]

I hoped it would. But I tried and it didn't work. In the logs of the medusa container i saw:
[2022-06-01 19:06:47,341] DEBUG: https://rgw_url:443 "HEAD /cassandra-backups HTTP/1.1" 403 0
Credentials was correct. Using aws cli i can list all files.
I didn't find any usefull information about this, if you could help me with that - it would be great

[adejanovski]

Let's roll with s3_rgw then. Thanks for pushing this PR!
