I think the query node shoud be manage by statefulset, because the index of disk ann need some pv; local disk sometime is not enough； I need mount a cloud pv. You can think about it

Thank you @Sallery-X. For the use of diskANN index, we expect NVMe local disks with higher IOPS. For example, AWS disk optimization series (such as m6id or m6gd series), or GCP's additional local SSD disk. The speed of ordinary cloud disks may not be fast enough, and we do not need the persistence of cloud disks. Of course, everyone will make their own choices based on their own needs. In the future, we may also support statefulset for deployment.
