> Refactor AbstractAppDataSnapshotServer so that subclasses don't need schemas

>                 Key: APEXMALHAR-2530
>                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2530
>             Project: Apache Apex Malhar
>          Issue Type: Improvement
>          Components: AppData

> 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.
