Timeouts in Power Query Functions

Chris Webb reminds us to look at timeouts in Power Query functions:

In the first post in this series I showed how the Power BI Service applies a limit on the total amount of time it takes to refresh a dataset in the Power BI Service, except when you initiate your refresh via an XMLA Endpoint. In this post I’ll look at the various timeouts that can be configured in Power Query functions that are used to access data.

Every time a Power BI Import mode dataset connects to a data source it goes through a Power Query query, and inside the code of that Power Query query will be an M function that connects to a specific type of data source. Most – but not all – of these M functions have the option to set timeouts. 

Read on to learn more about these timeouts, as well as other Power Query functions which have timeouts by default.
