Jacky Li commented on SPARK-24630:
----------------------------------
Actually I encountered this scenario earlier, so we have implemented some
commands for using SparkStreaming(or StructureStreaming) on Apache CarbonData,
you can refer to the StreamSQL section in this
[doc|http://carbondata.apache.org/streaming-guide.html] for more detail.
It is good if Spark community can use similar or same syntax, if possible, then
in future version of CarbonData can migrate to Spark's syntax.
> SPIP: Support SQLStreaming in Spark
> -----------------------------------
>
> Key: SPARK-24630
> URL: https://issues.apache.org/jira/browse/SPARK-24630
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.2.0, 2.2.1
> Reporter: Jackey Lee
> Priority: Minor
> Labels: SQLStreaming
> Attachments: SQLStreaming SPIP V2.pdf
>
>
> 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.
