This closes MRQL-79
> Add support for incremental query processing
> --------------------------------------------
>
> Key: MRQL-79
> URL: https://issues.apache.org/jira/browse/MRQL-79
> Project: MRQL
> Issue Type: New Feature
> Components: Run-Time/Spark, Streaming
> Affects Versions: 0.9.6
> Reporter: Leonidas Fegaras
> Assignee: Leonidas Fegaras
>
> This is a new feature for MRQL streaming: its task is to convert any
> stream-based MRQL query to an incremental query that merges the previous
> query results with the results of applying the query to the new data batches
> only. For example, it will be able to convert the MRQL PageRank query to an
> incremental PageRank query automatically. The basic idea was presented at
> ApacheCon'15 (page 28 in http://lambda.uta.edu/mrql-apachecon15.pdf ) as a
> future plan for MRQL. It will work on Spark Streaming mode for now, but later
> it will support Flink Streaming too.
