Concurency Control and Degree of Parallelism in PowerAutomate

By Vinod Thachin -

Concurrency control and Degree of parallelism are the options available in Power Automate triggers and Apply-each controls.

Using Concurrency Control option, We can control number of flows to run in parallel. Without enabling the concurrency control, power automate can trigger multiple instances of a flow. But enabling the concurrency control we can mention number of instances to trigger and run in parallel. If we trigger multiple flows they will be in waiting stage.

To enable PowerApps Concurrency control, select Settings and click on Concurrency control as below.




After enabling the Concurrency control, there will be Degree of Parallelism option. This will allow how many flows to trigger at parallel. 

In the above case, only 25 instances can run in parallel. If we get more than 25 instances they will be waiting status as below.

Similarly we can enable Concurrency Control for Apply-each and it will run parallelly.

Anyone comes in home takes my password and it just worked great most of the time. all these were with windows server 2003 and Dell machaines.

If you are running into a weird issue, where you get prompted for your credentials repeatedly in your local sharepoint server and was denied access to the site, even though you are using an administrator account, and if this happens only when you create a nice host header and on 80 port, then you are here at the right place - Just read the below. Method 1 works for me :  Click  Start , click  Run , type  regedit , and then click  OK . In Registry Editor, locate and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0 Right-click  MSV1_0 , point to  New , and then click  Multi-String Value .
