What

One shortcoming of the ConfigPersistence iface is that it doesn't give great type safety. If you ask for a workspace object but query the sync table, it'll happily try to return this. The error handling on it isn't very clear. Sometimes it might fail because json validation will catch the mismatch. If the validation succeeds though, then you can end up with a weird, hard-to-debug output.

This is relevant as we think about consolidating StandardSourceDefinition and StandardDestinationDefinition into a single struct ActorDefinition. Making that change will be safer if we check that class we are asking for matches the class declare in the enum.

How

• Add classname to AirbyteConfig. Build a decorate class that compares the classname in AirbyteConfig to class requested in getConfig(), etc, and the inputs into any write methods.
