What is external data sharing?
Fabric external data sharing is a feature that enables Fabric users to share data from their tenant with users in another Fabric tenant. The data is shared in-place from OneLake storage locations in the sharer's tenant, meaning that no data is actually copied to the other tenant. Rather, this cross-tenant sharing creates a OneLake shortcut in the other tenant that points back to the original data in the sharer's tenant. Data that is shared across tenant boundaries is exposed to users in the other tenant as read-only, and can be consumed by any OneLake compatible Fabric workload in that tenant. Wow, seems like a pretty massive feature, what are your thoughts?!
