How to avoid preview is Evaluating in Power BI Desktop

Hey everyone,

I'm currently working on developin a custom connector in Power BI desktop and have noticed a particular behavior when the checkbox of a table is clicked in navigator. Upon clicking, a "Preview is Evaluating..." message appears on the right side of the navigator, and it takes approximately 5-10 minutes for a truncated table to load. This loading message can be misleading for users, as they might assume they need to wait for the preview when they could instead click on "Load" to directly load the table into the data pane.

Are there any techniques or settings within the Power BI connector code or Power BI desktop application that could help mitigate this issue?

There is no remedy.  Whenever you change the meta data this will happen.

Yes, but they are not practical.  The essence of the technique is "Never ever change the meta data ever again".

Thank you for your response. Could you please clarify your explanation? I'm having difficulty understanding your point. I'm looking for a way to bypass the Preview of the table in Navigator when loading a table in Power BI Desktop via a custom connector.

There is no remedy.  Whenever you change the meta data this will happen.
