Juice is cool, but tradeoffs around which metadata store you choose end up being very important. It also writes files in it's own uninterpretable format to object storage, so if you lose the metadata store, you lose your data.
When we tried it at Krea we ended up moving on because we couldn't get sufficient performance to train on, and having to choose which datacenter to deploy our metadata store on essentially forced us to only use it one location at a time.
