This looks almost exactly like the kind of data store I need for an application. I have previously considered using minio (too inflexible wrt to adding more shards / replicas), a homebrew system based on something like ScyllaDB (needs code on top to act like a blob store) or S3/B2 (too slow and/or expensive wrt to transfer costs). Is anyone using this in production and can share a story of how stable and hard to run it is?
