With the upcoming 0.14 edition of dagster will partitioned (software-defined) assets be part of the API?

yup! in fact, partitioned assets are available in preview in our most recent release

I know. But so far I did not figure out how to use partitions in software defined assets. Would you have an example for me?

it's not the most concise example, but the hacker news assets demo contains partitioned assets. here's a definition for one: https://github.com/dagster-io/dagster/blob/master/examples/hacker_news_assets/hacker_news_assets/assets/items.py and here's a job that includes some: https://github.com/dagster-io/dagster/blob/master/examples/hacker_news_assets/hacker_news_assets/jobs/hacker_news_api_download.py

Thanks - I think the two links are great examples to what I need.

currently, all the assets within the same job must have the same partitioning (or no partitioning). we have a more flexible notion of a `PartitionMapping`: https://github.com/dagster-io/dagster/blob/master/python_modules/dagster/dagster/core/asset_defs/partition_mapping.py, an important subclass of which is `TimeWindowPartitionMapping`: https://github.com/dagster-io/dagster/blob/master/python_modules/dagster/dagster/core/asset_defs/time_window_partition_mapping.py

Do you have any plans to support a mix of non-partitioned and partitioned assets?

with our current apis, you can combine partitioned and non-partitioned assets in a single job
