Hi Anonymous 

 

First of all, I have to admit that I don't have experience in custom connectors, only some experience in Power Query. From your screenshot, the number of tables is not large, but the number of rows in preview is large. Is it possible to reduce the rows queried for preview in Navigator? Maybe you can only query top N rows for preview instead of the whole table.

 

Another option is to create Dynamic Navigation Tables in Navigator. I found below links that may be helpful:

100% Dynamic Navigation table with Web.Contents() - Microsoft Power BI Community

Custom Connector and Navigation Tables - Microsoft Power BI Community

Handling navigation for Power Query connectors | Microsoft Docs

 

Additionally, you could also seek for help at the Developer forum. Users there have more experience in developing custom connectors.
