👋 I would like to create a daily partitioned asset that covers from 2021-01-01 to the future. Historic data (from 2021-01-01) is aggregated from different upstream data sources while present day data is aggregated from other upstream data sources. What would be the best way to essentially concatenate the historic data with present data into one daily partitioned asset?

Because the data comes from different sources, I feel like historical data should be its own asset, and new data is a separate asset, which is then unioned downstream when used
