I am trying to understand how sling-distribution-journal works. As per the documentation, it says that persisted log is created.
On real AEM Cloud service production environment, what is framework used for append-only log implementation? Is it Apache Kafka or Apache sling-distribution-journal provided framework? As per the diagram provided, it says this log file is written outside of AEM instance. I think this LinkedList stores all the log info but my doubt is what happens after, how this info is persisted in a file. I could not find the implementation.
AEM Cloud uses Apache Kafka as the distribution backend. Some insights can be found in https://adapt.to/2019/schedule/sling-content-distribution-for-the-cloud
