Best way to delete assets programatically in AEM as a Cloud Service

Question

Hello everyone,I'm creating a scheduler to clean a folder where I have to delete assets that are more than X days old.The logic is similar to when the expiration day of the asset is reached, but I've to add delete the asset from the folder in author.-Unpublish-Unpublish in Dynamic Media.-Unpublish from Brand.-Delete asset  My question is, what is the best way to delete an asset in AEMasaCS? i have something similar to: Session session = resourceResolver.adaptTo(Session.class);
//unpublish assets from Brand Portal
this.damSyncService.unpublishResourcesFromMP(assetPaths, resourceResolver);
for (String assetPath : assetPaths) {
    ReplicationStatus assetReplicationStatus = replicator.getReplicationStatus(session, assetPath);
    if (assetReplicationStatus.isActivated()) {
         replicator.replicate(session, ReplicationActionType.DEACTIVATE, assetPath);
         resourceResolver.getResource(assetPath).adaptTo(Node.class).remove();
    }
} i'm using node.remove() as the previous aem versions thanks in advance

Selective unpublished should work. I don’t have dynamic media configured on my local to check the workflow but you can reference this https://docs.mktossl.com/docs/experience-manager-cloud-service/content/assets/dynamicmedia/selective-publishing.html?lang=en#selective-unpublish-manage-publication

Hi, here it's my solution

    private void deleteFromScene7(Resource assetResource, ResourceResolver resourceResolver) {
        try {
            S7Config s7Config = s7ConfigResolver.getDefaultS7Config(resourceResolver);
            String scene7ID = this.s7Service.getScene7ID(assetResource);
            if (scene7ID == null || s7Config == null) return;
            if (assetResource.isResourceType(NT_SLING_FOLDER)) {
                s7Service.deleteFolder(scene7ID, s7Config);
            } else if (assetResource.isResourceType(NT_DAM_ASSET)) {
                s7Service.deleteAsset(scene7ID, s7Config);
            }
        } catch (Exception le) {
            logger.error("Error trying to delete asset from Scene7", le);
        }
    }

Hi @victortoledo,If in your code you have Session object I would go with below code: session.removeItem(assetPath);session.save(); Why? Because you need only path to asset you would like to remove. You do not have to fetch any object, and do any other unnecessary operations. Of course using JCR api is probably not the most elegant but in this case it will be most effective.Alternatively you can consider to use Sling api, but this will cost you one additional operation - to retrieve/create Resource object. In my opinion, because you do not want to ready anything specific from resource object this is a bit redundant operation. But of course using Sling api, is always preferable instead of using JCR api which is low level api.So the same operation using Sling api will be like that: Resource res = resourceResolver.getResource(assetPath);resourceResolver.delete(res);resourceResolver.commit(); The way you did it so far, looks to be the less effective way. First of all you are mixing 2 apis in one call starting with Sling, and running final operation from JCR api. But more important, is that you are doing unnecessary operation, creating Resource and Node objects.
