We are currently using the Ceph Octopus version and have some questions regarding a specific commit in librbd ( https://github.com/ceph/ceph/commit/081d28ae7ca46fd1f40034cc558def77a95a9294 ). Could you please clarify why Ceph implements ordering for overlapping IO? Our understanding is that overlapping IO in block storage can typically be parallelized. We are curious about which components of Ceph depend on this feature. Additionally, we noticed that this feature was removed in the subsequent Pacific version. Could you provide some insight into the reasons behind this decision? Thank you for your assistance. Best regards, shibo
