Automatically publish content from Master-Publish instance in Asset Offloading

Hi All,

We have implemented Asset offloading approach i.e Author instance (Master). Now Slave instance replicate back processed content to Master instance as per Offloading approach.

Now we want to replicate the content that got reflected in Master instance to Publisher.

Observed that replication is not happening on Master instance to Publisher after Slave instance completes its replication back to Master.

Could you any provide any points on this.

Thanks

It's not a perfect approach, however, it works on my test env. Not sure, what is your real business case; you might need to revisit and improve the launch configuration.

Event Type : Modified,

Node Type : dam:Assets

Path : /content/dam(/.*)

Workflow : Your custom WF

Exclude LIst: cr:lastModified,dc:modified,jcr:lastModifiedBy,imageMap,event-user-data:changedByWorkflowProcess,dam:extracted,simsearchVersion,jcr:lastModified,dc:modified,dc:format,jcr:lastModifiedBy,imageMap,dam:scene7(.*),event-user-data:changedByWorkflowProcess

Run Mode(s) : Author

      Yes offloading is working perfectly fine with all metadata & renditions to Master but replication from Master to Publisher is happening with out Renditions.

      Could you share details to be mentioned in launcher in each param that would be available on Master.

        Do you mean that offloading (the worker instance) does not send rendition and metadata back to the master? Despite the Publishing process, does offloading topology work?

          Hi, yes metadata node is created after changing event type to 'Modified',but observed that workflow instances are created & getting triggered continuously at the back-end & publishing it to instance. Also thumbnails are not generated in renditions folder(only original is available).

            AEM offloading workflow creates "jcr:content/metadata" node. The node is empty up until a worker extracts and sends metadata to the master.

            Can you test with "Modified event" and set Run Modes to Author only.

              Yes created a custom workflow launcher and did. It is getting published to Publisher but with no metadata node on asset.

              Event Type : Created, Node Type : nt:unstructured, Path : /content/dam(/.*)/jcr:content/metadata,

              Run Mode(s) : Author & Publish, Conditions : dc:format!=,

              Workflow : Scheduled Page/Asset Activation

              Tried few diff scenarios as well but not working as expected. Any pointers here.

                You can try to create an additional workflow launcher and set a trigger to when metadata for an asset is created.

                  @ Berliant,

                  Tried update as suggested DAM Update Asset Offloading workflow, but things didn't work out as expected.

                  Asset is getting replicated to Publisher as soon as it uploads to Master instance i.e before creation of renditions.

                  Throwing exceptions like "com.day.cq.dam.core.impl.AssetImpl getMetadataValue: metadata node does not exist for asset",

                  "SlingRequestProcessorImpl service: Uncaught SlingException java.lang.NullPointerException: null" etc.

                  Could any one suggest any other ways for publishing content to publisher as soon as Offloading of renditions on Master is complete.
