Load data from API into Datamart

[Anonymous]

Hi

I currently use dataflows to query an API and then use this information within various Power BI reports. For different time periods I am setting up multiple queries as some of them can take a while to run.

I think it would make sense to load this API data into a Datamart.

How would I get a dataflow to update the datamart without losing the older data in the datamart. ie could it be setup to refresh and add records that are new and over write records that are already there?

Hi @Anonymous ,
Thanks for @lbendlin  reply.
Here's what I've added
Power BI Data Marketplace supports an incremental refresh policy that allows you to refresh only the data that has changed or been added since the last refresh, rather than reloading the entire dataset. This method is effective for managing large datasets and ensuring that your data market is up to date without losing historical data. To set up an incremental refresh for Datamart, you need to configure it in the Datamart editor.
To automate the process of updating a data market, you can use the Scheduled Refresh feature. This allows you to specify how often the data market should check and merge new or changed data in the data stream. You can set this from the Datamart Settings page.
You can refer to this documentation for more information on setting up this feature

Load the data into separate dataflows. Then only refresh the dataflows that need refreshing.
