Fix Version/s: 3.8.0
> 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
> Reporter: David Yan
> Assignee: David Yan
> Fix For: 3.8.0
>
>
> 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.
