Talking about transactions in Redis, one area came on top of my head is metadata in file systems. I've seen colleagues/collaborators run large-scale training on a distributed file system w/ a billion files, which puts a lot of pressure on the metadata part. They tried a few options and Redis was one of them. It's fast and Lua is good enough to support metadata ops. But the thing is that it cannot scale (or Lua is gone) and may lose data from time to time, which is annoying. It looks like this durable-transactional combination may fit in. Will wait to see how this is unfolded.
