FrontDoor API Item Limit Exceeded Despite Smaller Chunk Size

Putting a one second sleep in the purger in between calls appears to fix this:
AzurePurger.php:95

 $firstChunk = true;
    foreach ($chunks as $chunk) {
      /**
       * Microsoft CDN Purge endpoint will throw item limit error if multiple requests are received too quickly exceeding the 100 item limit
       */
      if(!$firstChunk){
        sleep(1);
      }
      $this->purgeChunk($chunk);
$firstChunk  = false;
    }

@alan.wallace let me know if you are still experiencing this issue. I don't have any projects using FrontDoor, but maybe I can trigger this behavior with Azure CDN if I increase my chunk size. Will try this out over the next few weeks.

We are seeing this as well with the Azure CDN. Reach out if you want more info.

Have added some code similar to comment #3 to incorporate a delay - which is configurable. Having trouble creating an MR for some reason, MR url gives me 404. Maybe it was the Xmas break or the Covid... here is the diff: https://git.drupalcode.org/issue/azure_cdn_purge-3351085/-/commit/0c3c9a...

Opened a MR with your feature branch, and attached a patch to facilitate testing. @joel please test the patch, if it works we can merge this into the 1.0.x branch. @alan.wallac would be nice to get your input on this fix as well, see if it works for your scenario.

Will test now, thanks @smulvih2 and @alan.wallac for the original solution.

Testing complete, works well. Thanks again!

This has been merged with the 1.0.x branch and will be included in next release.

This has been included in 1.0.4, thanks guys!
