Currently, I am using PowerBI free account and MongoDB as a source. Imported all the required collections from my database and tried to expand the arrays in those collections in Power Query at PowerBI Desktop. It takes a lot of time to expand the columns in those arrays and never ends. Can you please let me know the alternative approach? Will my free trial account affect the performance?
Data size < 1GB.

@amitchandak Finally, made progress with this expansion issue by creating a parameter containing the latest DateTime. My collection has updated DateTime column.
Firstly, filtered the update DateTime column in the collection with my parameter and then expanded the table. Later on, we can manage those parameters in the PowerBI service. With the expansion, data size might be increased over 1GB.
But the refresh on PowerBI service is taking very long time after I remove the latest DateTime in newly created parameter. Is that because of my free trial account? If I take Pro license, will the refresh issue going to be resolved?

Can anyone please explain how to expand using M parameters or help to resolve this issue?
Thanks
@RGouda , Put a filter step and then expand using M parameters. You can change the filter in the power bi service if needed.
