Is there an easy way to pass persistent data between flow runs?

Hi @Ziyao Wei, Prefect Core has hooks for storing and retrieving cached data on your own but doesn't persist data between runs because everything is stored in-memory. To pass persistent data, you'll need a persistence layer like Prefect Server / Cloud. For more information on caching, this page of the docs should have everything you need!

Cool, thanks! Before I digging into this, a quick question - we are using our own instance and not Prefect Cloud, does that change things?

Your own instance of Prefect Server?
If so, nope! That works as well.
