Running multiple functions under a single function app

Question

Hi, if I deploy multiple queue triggered functions under one azure function app resource then could there be any threading issues?

As in, if multiple functions are being triggered then could the threads/memory be shared or is there a risk of threads/memory leaking data to one another?

Each time when either of the function is triggered it will be processing a data file that will be stored in a time stamped folder, so at a given time though only one function would be accessing files from a particular time stamped folder.

• Azure Function App
• queue_triggered_function_one
• queue_triggered_function_two
• queue_triggered_function_three
• queue_triggered_function_four

-Storage

• folder_one
• folder_two
• folder_three
• folder_four

At a given point in time any of the data in a given folder will only be accessed by a single queue triggered function.
