             Summary: Add support for Storm streaming
                 Key: MRQL-90
                 URL: https://issues.apache.org/jira/browse/MRQL-90
             Project: MRQL
          Issue Type: New Feature
          Components: Streaming
    Affects Versions: 0.9.8
            Reporter: Leonidas Fegaras
            Assignee: Leonidas Fegaras


This task is assigned to Achyut Paudel achyut.paudel2@mavs.uta.edu as part of his MS thesis at UTA. This extension will allow MRQL queries to run on Apache Storm DSPE (distributed stream processing engine). The stream unit is a Tuple with just one component: a Bag<MRData>, which is a buffer of MRData used for batch streaming. Each MRQL physical operator will correspond to 1-3 Storm bolts, while a source operator will correspond to a spout. For example, the MapReduce(m,r,X) operation will consist of 2 bolts: a bolt with a map function m (a Bolt subclass with an attribute m) that applies m to the input data, and another similar bolt with the reduce function r. These two bolts will be connected in the Storm topology with a Storm group-by operation. The query evaluator will first generate a Storm topology from a physical plan and then will use the Storm evaluator to evaluate the topology. The only new components needed for these extensions are: 1) Bolt and Spout subclasses to capture MRQL operators 2) a Storm topology generator from MRQL plans.
