@PublicApi
public class ApolloPersistedQuerySupport
extends PersistedQuerySupport

This persisted query support class supports the Apollo scheme where the persisted query id is in ExecutionInput.getExtensions().

You need to provide a PersistedQueryCache cache implementation as the backing cache.

See Apollo Persisted Queries

The Apollo client sends a hash of the persisted query in the input extensions in the following form

     {
      "extensions":{
       "persistedQuery":{
        "version":1,
        "sha256Hash":"fcf31818e50ac3e818ca4bdbc433d6ab73176f0b9d5f9d5ad17e200cdab6fba4"
      }
    }
  }
