Memory storage in PBI Service

Hi everyone,

I'm trying to get some clarity on how data is stored within Powerbi Service through the dataflow process. For context I have a flow which consists of multiple dataflows connected to each other.

-The first dataflow stages data from the source and does some folded transformations using computed entities.

-The resulting computed entities are then passed to another set of dataflows which perform further operations on them.

-The computed entities from these dataflows are then used to make a PBI dataset that the dashboard then uses.

I am working in a PPU workspace. From my understanding, the initial data imported to PBI from the source is stored in Azure BLOB which has a 100TB capacity, and the computed entities are calculated in-memory. However, once the computed entity is calculated and passed to the next dataflow, is the resulting computed entity also stored in Azure BLOB? Further more, is the resulting dataset that the dashboard uses also stored somewhere in BLOB?

Any help would be greatly appreciated.
