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