> Currently AbstractAppDataSnapshotServer requires the users of the operator to set up
the schemas, query deserializer, result serializer, query processor, etc. A simple query processing
operator should not need all that. Let's have a more abstract app data server that only requires
an embeddable query input operator, which is necessary if the query needs to be processed
immediately without delay, which can be significant if the DAG has significant latency.
