When going through DAX overview documentation on the following https://docs.microsoft.com/en-us/dax/dax-overview,
under the Calculated Column heading, I couldn't understand the highlighted information in the following statement:
"(calculated) Column values are only recalculated if the table or any related table is processed (refresh) or the model is unloaded from memory and then reloaded, like when closing and reopening a Power BI Desktop file."
Does it mean, that whenever we close the Power BI Desktop file, the model is unloaded from memory? does the memory is used like Cache?
Would anyone please help me understand what actually happens in practical world? Thank you for giving your valuable time and support!
