@byroot We'd like to default to replicas for all reads, it reduces load on the writers. It's a little taxing to then have to wrap all write queries in a `connected_to` block though.

Perhaps we could write a customer resolver for this, we haven't decided. It could be nice though if you could configure AR to send writes to the correct database though.

@byroot If we moved that up we were thinking of adding an AR configuration item that would allow for automatically switching to the write database for write queries.

The motivation is that we'd set the default role for an abstract model to be the reading role. e.g.

```
class Foo < ActiveRecord::Base
self.abstract_class = true
self.default_role = ActiveRecord.reading_role
end
```

Then if you had a model Bar, that inherited from Foo, then `Bar.first` would default to the replica database.
