Probably a bit hacky, but here’s a helper function I wrote for converting

metadata_entries

to a more convenient format; it takes advantage of dagster’s design decision to subclass NamedTuple and include the data as the first value

def get_asset_metadata(ass: AssetMaterialization, metadata_label=None):
    metadata_filter = lambda entry: (metadata_label is None) or (entry.label == metadata_label)
    return {entry.label: entry.entry_data[0]
                for entry in 
                    filter(metadata_filter,
                    ass.event_log_entry.dagster_event.event_specific_data.materialization.metadata_entries)}
