I really like the idea of tiering a log device such that you go from memory -> nvme -> object storage. You get some nice properties like fast low latency commit times from NVMe, read your own local writes (usually good enough), but have most of your cold data on cheaper durable object storage with some intelligence to pull down/warm up pages when you suspect you'll need them. It'd be nice if this had a more language-agnostic frontend like gRPC or something.
