             Summary: Introduce ReadOnlyDistributionQueue API
                 Key: SLING-8065
                 URL: https://issues.apache.org/jira/browse/SLING-8065
             Project: Sling
          Issue Type: Improvement
          Components: Content Distribution
    Affects Versions: Content Distribution Core 0.3.4
            Reporter: Timothee Maret
            Assignee: Timothee Maret
             Fix For: Content Distribution Core 0.3.6


We currently export an [SPI|https://github.com/apache/sling-org-apache-sling-distribution-core/tree/master/src/main/java/org/apache/sling/distribution/queue/spi] with a fully editable queue, [DistributionQueue|https://github.com/apache/sling-org-apache-sling-distribution-core/blob/master/src/main/java/org/apache/sling/distribution/queue/spi/DistributionQueue.java].

Some distribution queue implementation are read-only meaning that they don't provide the ability to add/remove items. Example of such read-only queue is an implementation on top of an append only messaging service.

In this issue, I suggest to introduce add and export the {{ReadOnlyDistributionQueue}} interface. The existing read-only method signatures from {{DistributionQueue}} would be moved from {{DistributionQueue}} to {{ReadOnlyDistributionQueue}}. {{DistributionQueue}} would extend from {{ReadOnlyDistributionQueue}}. This change is backward compatible.
