What PartitionMapping do I use for a non-partitioned asset to a specific set of partitions?

[dagsir[bot]]

Hello, I need to make a dependency between non-partitioned upstream asset and a set of partitioned downstream assets. Hower, there is nothing in docs about what type of PartitionMapping should be used in such case. Can someone provide working example? Thanks.

To help me understand the question a little better, can you spell out the behavior that you're looking for in a little bit more detail? I.e. give a basic example with some contrived assets and partitions and specify the dependencies you're looking for?
