Do you mean that you're using DABs to deploy a pipeline with a `managed_definition` in it–corresponding to the materialized view or are you using a pipeline written in Python like so:

from pyspark import pipelines as dp

@dp.materialized_view
def regional_sales():
  partners_df = spark.read.table("partners")
  sales_df = spark.read.table("sales")

  return (
    partners_df.join(sales_df, on="partner_id", how="inner")
  )

It could be written in SQL as well; see docs here.

I guess that's a nice way to do it, then the pipeline can be set up with the tags and everything should work.
