Dear Prefect devs, I've noticed that there's internal work in progress on supporting custom cache storage (https://github.com/PrefectHQ/prefect/issues/2104#issuecomment-594811242), are there any early versions available for public to try out?

Hi! We are actively working on the target/results solution I referred to in that issue but it’s not quite ready to try out altogether yet; we are hooking up the pipeline logic this week and the target semantics on the task decorator follows along right after that (so probably in the next 1.5-2 weeks everything should be hooked up enough in a branch you can try out). We think that this solution may solve a lot of problems for cache users, but definitely would like your input on that issue if you don’t think so (and/or you kicking the results/target solution around for us with your use case when we have a branch ready. I can ping you directly when it’s up!)

Thanks Laura, please ping me once the first version of persistent caching is available.

Will do! 👍
