title: For_each concurrency and variable interference in Azure Logic App
body: <p>I have a logic app that uses For_each to iterate through email attachments and saves them to an Azure Files container.</p>
  
  <p>Depending on some conditions, I want the attachment stored with a different name or at a different path, but the default concurrency of for_each is concerning; I have path and file name variables set at top level and I'm setting them in the loop as conditions are met.</p>
  
  <p>Is there a way to be sure that these variables will hold the value I'm setting in that iteration without setting concurrency to 1?</p>
  
  <p>It seems like it's working correctly with default concurrency, but I'm going to set concurrency to 1 until I'm sure about whether or not these iterations can interfere with each other in terms of setting variables.</p>
