Read data from a clustered table
You can read data in a clustered table using any Delta Lake client that supports reading deletion vectors. For best query results, include clustering keys in your query filters, as in the following example:

Hi,
Thanks for the response. Not using Databricks, we only use Databricks to create views, Power BI uses Power Query functions to access directly to Storage Accounts.
We opted for that approach as it takes too long to spin up a cluster when people want to access, alternative is to run a cluster all day, but we didn't want to do that due to cost.
