But you changed the schema from the documentation. In the guide, CountryCode is the primary key for the country table/cache. In your schema, you have country_id in the Country table and country_code in City.
Two possible solutions: 1. Change the primary key of Country from country_id to country_name 2. Change the affinity key in City from country_name to country_id The key (pun intended) is that the key for Country and the affinity key for City are the same. > On 19 Mar 2019, at 08:31, NileshKhaire <ngkha...@gmail.com> wrote: > > Hello, > > Thanks for response.
