Hi, we’re using Daily + Dynamic partitions and Daily + Monthly partitions for various assets. I wanted to see if I can display some metadata about each partition on the UI.
ie I want to show how record counts for each partition, and some additional data flags. Is this something that is supported ?

Hi!

Since partitions can be seen as materializations of assets, you can attach any metadata that you would add to an asset onto a partition materialization.

If it's a numerical value (such as row count), it'll be plotted across the partitions.

Here's another example of how you can see how each daily partition can track row count with metadata!

And if you go into the asset catalog to see this metadata across partition materializations, too
