[jira] [Created] (SPARK-24630) Support SQLStreaming in Spark

Jackey Lee created SPARK-24630:
----------------------------------

             Summary: Support SQLStreaming in Spark
                 Key: SPARK-24630
                 URL: https://issues.apache.org/jira/browse/SPARK-24630
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.2.1, 2.2.0
            Reporter: Jackey Lee


At present, KafkaSQL, Flink SQL(which is actually based on Calcite), SQLStream, StormSQL all provide a stream type SQL interface, with which users with little knowledge about streaming,  can easily develop a flow system processing model. In Spark, we can also support SQL API based on StructStreamig.

To support for SQL Streaming, there are two key points: 
1, Analysis should be able to parse streaming type SQL. 
2, Analyzer should be able to map metadata information to the corresponding 
Relation.
