Schedule refresh one table of data model

Hi Rahul_SC,

Thank you  for reaching out to the Microsoft fabric community forum.

In Power BI there is no option to schedule refresh for only one table inside a dataset. Refresh always happens for the full dataset. Since only your MySQL table is changing multiple times in a day, you have two practical options, you can enable Incremental Refresh on the MySQL table so only new or changed data gets refreshed instead of the full history. This reduces load and refresh time or  to separate the MySQL table into a different dataset and connect it using a composite model  this way you can keep frequent refresh for MySQL and normal refresh for the rest. MySQL also supports DirectQuery using an on-prem gateway, but performance and RLS behavior should be tested properly before using it in production. Unfortunately, there is no direct way today to refresh only one table inside a single dataset.
