Are there any SQL server variants (i.e MySQL, Postgresql etc) that handle replication as well as couch db does and offers client side replication (2 way)?
I'm in the early stages of my app which is currently using PouchDB / CouchDB as a key point about the app is being able to go offline then replicate when back online. I know the servers themselves can replicate but I'm basically looking to have an offline version of the database available to the client as well (which is what PouchDB / CouchDB achieves).
