Push replication is a type of replication that occurs between local repositories on two different Artifactory instances. When push replication is configured, the Artifactory instance on which the job has been configured pushes the contents of the repository to be replicated to the destination repository.
The distribution of release bundles to edge nodes is an optimized form of push replication performed by the replicator. Normal push replication directly from a local repository is not supported for edge nodes.
Similarly to reasons for pull replication, artifacts that are pushed to Edge nodes are curated for release, as such, it does not make sense to push entire repositories to edge nodes.
