-------------------------------------
Summary: 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
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.
