I'd like to start using the

asset_partition_key_range_for_output

But it seems like the default io_manager and s3_pickled_io_manager does not support this. What are my options here to start using this?

you might just have to write your own IO manager, but it's a pretty straightforward process and a very common thing to have to do for more advanced situations like this.

Thanks Zach! Another option would be to use the

mem_io_manager

, if that could fit your needs

I filed an issue to track this: https://github.com/dagster-io/dagster/issues/14332
