When you materialize a dagster asset, can you specify which partition to materialize?

Yes, when you materialize a partitioned asset in Dagster, you can specify which partitions to materialize. The documentation describes that when you materialize a partitioned asset, you choose which partitions to materialize, and Dagster will launch a run for each selected partition. If you choose more than one partition, the Dagster daemon needs to be running to queue the multiple runs. To materialize specific partitions, you would typically use the Launch runs dialog on an asset's Details page in the Dagster UI, where you'll be prompted to select the partitions you want to materialize. After a partition has been successfully materialized, it will display as green in the partitions bar on the asset's details page. For more detailed examples of working with partitions, you can refer to the Hacker News example provided in the documentation.
