User Synchronization vs StorageResourceProvider API Hi all, just wanted to get everyone’s opinion on User Synchronization[1] (using Sling Content Distribution[2] (SCD)) in AEM 6.2.Right now in AEM 5.6.1 we’re using some custom Forward Replication/Reverse Replication (FR/RR) for all UGC, including user profile preferences. From our experience thus far, this is probably the worst thing in the world, and we’ve only got about 15-20k active users.I went ahead and setup User Synchronization in my local dev environment (1 author, 2 publishers) and it’s working out pretty well for any preference modifications made under the rep:User node.

I can only hope that the answer is no but I don’t know for sure. My guess is that SCD doesn’t have all of the overhead that FR/RR has from the AEM interface using replication agents, workflow instances, leaving behind var/audit logs, etc.I also wante
