Hi Roman, Danil, Thanks for submitting your talk proposal 'Make RBD snapshots independent with COW on radix trees'. The program committee decided that this topic would benefit from an interactive discussion, so instead of accepting this as a conference talk, we're setting aside a time slot during the developer summit on Tuesday. You can see the (tentative, WIP) schedule here: https://pad.ceph.com/p/cephalocon-2020-dev-summit You'll get a notification from LF for your original talk submission, presumably saying it's declined, which you can ignore. Thanks! sage
