Hello everyone - We are using Delta Sharing to enable our customers to access their data in Power BI, but our customers are complaining that the imports are taking way too long (hours) because they have no way to simply ask for e.g. the last 30 days of data or some filter like that. Are we missing something obvious? because if the user has to reimport their 100 million + rows of data every time, then this will be unusable for them. Any tips/tricks or features, capabilities we are unaware of? Thank you in advance for your insight.

You can request a limit on rows or pass partition columns to reduce the amount of data requested.
