Hi Guys, Regarding https://review.openstack.org/#/c/49316/, we have been working on the implementation of this feature for ~5 months and unfortunately it's not in icehouse yet. We have been testing this feature againt Amazon S3 and other S3 servers and it's working and it can handle large image/snapshot objects. To complete this, the following BP needs to be re-opened as zhiyan left the mesage there. https://blueprints.launchpad.net/glance/+spec/s3-multi-part-upload We really hope to have this feature in the next release so can someone please take this one ? thanks, - Ozawa
