Have you looked at the Ceph User Surveys/Census? https://ceph.com/ceph-blog/ceph-user-survey-2018-results/ https://ceph.com/geen-categorie/results-from-the-ceph-census/ > But I since nobody here is interested in a better rgw client for end > users. I am wondering if the rgw is even being used like this, and what > most production environments look like. Your end-user client thread was specifically asking targeting GUI clients on OSX & Windows. I feel that the GUI client usage of S3 protocol has a much higher visibility to data size ratio than automation/tooling usage. As the quantity of data by a single user increases, the odds that GUI tools are used for it decreases, as it's MUCH more likely to be driven by automation & tooling around the API. My earliest Ceph production deployment was mostly RGW (~16TB raw), with a little bit of RBD/iSCSI usage (~1TB of floating disk between VMs). Very little of the RGW usage was GUI driven (there certainly was some, because it made business sense to offer it rather than FTP sites; but it tiny compared to the automation flows). My second production deployment I worked was Dreamhost's DreamObjects, which was over 3PB then: and MOST of the usage was still not GUI-driven. I'm working at DigitalOcean's Spaces offering now; again, mostly non-GUI access. For the second part of your original-query, I feel that any new clients SHOULD not be RGW-specific; they should be able to work on a wide range of services that expose the S3 API, and have a good test-suite around that (s3-tests, but for testing the client implementation; even Boto is not bug-free). -- Robin Hugh Johnson Gentoo Linux: Dev, Infra Lead, Foundation Treasurer E-Mail : robbat2@xxxxxxxxxx GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85 GnuPG FP : 7D0B3CEB E9B85B1F 825BCECF EE05E6F6 A48F6136
