Folks,

Is there a way to clear entire dispatcher cache at a time on AEM as a cloud service 

Our requirement is to clear entire dispatcher cache instead of clearing it based on individual Paths

I hope you are considering both dispatcher and CDN.

 

For dispatcher cache, the cache can be cleared by running webtier pipeline. Which is deploying your code again.

 

For CDN, you can raise Adobe support ticket. They can clear all CDN cache. FOr resource-based CDN cache flush, they can provide you a key. This key can be used with Curl command.

I think running a webtier pipeline clear the dispatcher cache on cloud.
Otherwise you can create something custom as mentioned here https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/implementing/content-delivery/caching#explicit-invalidation

    @h_kataria 

    The link mentioned by you can clear cache for individual paths

    I am looking for a solution to clear entire dispatcher cache in AEM cloud at once without specifying paths

      Yes, because as far as I know, there is no direct way to clear complete dispatcher cache apart from running the webtier pipeline. All other custom solutions provide path based invalidations only. One can also think in that direction if there are some specific paths which one has to target which can achieve the required goal in which case a custom solution like SCD or replication APIs can be implemented as clearing entire dispatcher cache is rather a rare scenario.

          Thanks @aanchal-sikka 

          Is there a way to flush entire dispatcher cache in AEM cloud programmatically without running the pipeline ?

            I am not aware, if its possible.

             

            If you facing scenarios for complete dispatcher flush frequently, you should review Dispatcher caching strategy. It is also discussed on https://cqdump.joerghoh.de/2024/06/12/my-view-on-manual-cache-flushing/ ,
