Storing metadata and timestamp in /var/project/storeData

[georhe6]

AEM as cloud service Hi Team, We need to store metadata — specifically the page path and timestamp — so that a scheduler can later pick it up and create a content package based on that path. Can we store this data under /var/project/storeData in AEM as a Cloud Service? We intend for this data to exist only on the author instance and not be replicated to publish. Thanks, Geo

Hi @georhe6 

In AEM as a Cloud Service, storing metadata like page path and timestamp for later processing by a scheduler is a valid use case. Yes, you can store this data under /var/project/storeData, but there are a few important considerations:

Recommendations:

1. /var is appropriate: The /var node is designed for transient, non-replicated data that is only needed on the author instance. Your path /var/project/storeData is suitable for such storage, especially since you don’t want this metadata replicated to publish.
2. Author-only data: By default, anything under /var is not replicated to publish, aligning with your goal.

You can store the data programmatically using a Sling POST or via a service user and ResourceResolver, like:

Map<String, Object> properties = new HashMap<>();
properties.put("pagePath", "/content/your-site/your-page");
properties.put("timestamp", System.currentTimeMillis());

ResourceResolver resolver = ...; // get with service user
Resource parent = resolver.getResource("/var/project/storeData");
if (parent != null) {
    resolver.adaptTo(PageManager.class).create(
        parent.getPath(),
        "entry-" + UUID.randomUUID(),  // unique node
        null,
        properties
    );
}

Or using JCR API:

Node storeData = session.getNode("/var/project/storeData");
Node entry = storeData.addNode("entry-" + UUID.randomUUID(), "nt:unstructured");
entry.setProperty("pagePath", "/content/your-site/your-page");
entry.setProperty("timestamp", Calendar.getInstance());
session.save();

Make sure you:

• Use a system user with write permissions to /var/project/storeData.
• Register the mapping in your repoinit script if the folder needs to be created during deployment.

Hope this helpful.
