I couldn't understand this one

This should be edited for sure! Imagine the scenario where you have a data source with schema and resolvers.
Then you realize that for example, the Postgres password is wrong. You should be able update that without creating the whole thing again.

BTW, this made me realize that we need to receive pubpsub notifications when a data source is saved. You asked me that yesterday and I was only thinking the scenario where a user creates a data source (which means nothing to sync server w/o schema and resolvers). Sorry, that's an oversight on my side.
