Hi. How can I check whether a specific partition of an asset is materialized? I know that is possible for an asset:

if context.instance.get_latest_materialization_event(AssetKey("my_asset")) is not None:
   pass

Maybe:

asset_key = ...
partition_key = ...

materialization_counts = context.instance.get_materialization_count_by_partition([asset_key])
materialization_count = materialization_counts.get(asset_key, {}).get(partition_key, 0)
is_materialized = materialization_count > 0

here's an example: https://github.com/dagster-io/dagster/discussions/16132

Ah, I didn't find that discussion thread. Thank you for the hint 😁
