*Operator adoption:*
You asked whether there is data about operators using Swift in Kolla. One of the reviewers, Roman Krček, has already pointed to the OpenStack User Survey which shows that ~40% of production deployments run Swift, with another ~15% either testing or interested [1]. This indicates that object storage remains critical for many operators. [...]
Chiming in from a general OpenStack (not necessarily Kolla) user perspective, in OpenDev we have a mix of providers with Swift and with a Swift-like RadowGW API backed by Ceph. We only use the Swift providers for publishing CI logs because Ceph-based providers complained that their configuration didn't scale to the thousands of containers and billions of objects we were constantly adding and removing. I get the impression RadosGW is a convenient way to avoid deploying resources for yet another storage service if you're already depending on Ceph for other reasons, but has its own limitations and is not always a suitable substitute for actual Swift. -- Jeremy Stanley
