Pull replication refers to a replication process unique to Artifactory remote repositories. When configured, pull replication allows a remote repository to pre-populate its cache with Artifacts available in a repository on another Artifactory instance.
Pull Replication is not supported at all on Artifactory Edge Nodes.
In order to fit the distribution model, Artifactory Edge Nodes can only create Smart Remote Repositories. These are special remote repositories that proxy other Artifactory Repositories, which allows for keeping certain properties synchronized with cached artifacts upstream.
The use of Smart Remote Repositories allows customers who do not want to create full release bundles to avoid the overhead of doing so.
Because customers would still want to curate which artifacts would actually be available for release in this scenario, it doesn’t make sense to synchronize the full contents of these repositories via replication, thus this feature is not supported on Edge nodes.
