Hello Wuerike,
My name is Ben Flast, I’m the product manager for Atlas Data Federation. We do have guidance about how to use paths and what to keep in mind when partitioning to optimize performance at the links below. But partitioning can definitely be a challenging task, and guidance can differ based on your underlying data and the query patterns you plan to use. If you’d like, please throw some time on my calendar and we can discuss in detail: Calendly - Benjamin Flast
Best,
Ben
