Set Azure functions timeout in days or more than 24 hours.

Issue:

·       How to set functions timeout in days or more than 24 hours?

Solution:

 

Azure functions have various timeout values which depend on hosting plan e.g. default timeout value in consumption plan is 5 min which can be further increased to 10 min via updating functionTimeout property in host.json file.

 

You can get complete list here,

Azure App Services and Function App: Azure Functions timeout

and

https://docs.microsoft.com/en-us/azure/azure-functions/functions-host-json#functiontimeout

 

But if you check it carefully, it allows you to define time in hh:mm:ss format where H-hours, m-minutes and s- seconds.

Now you can say I can define it like 25:00:00 which is more than 24 hours but it is invalid format and you may get function runtime error. The range for hh is 00 to 23.

 

Then how to solve this problem.

And life savor is https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-timespan-format-strings#the-constant-c-format-specifier

 

For 2 days you can define it like 2:00:00:00 where 2 is the optional and it is the number of days, with no leading zeros

 

Problem solved. Enjoy.
