> Add SQL support

> Key: GEARPUMP-217
> URL: https://issues.apache.org/jira/browse/GEARPUMP-217
> Project: Apache Gearpump
> Issue Type: New Feature
> Components: streaming
> Affects Versions: 0.8.1
> Reporter: Manu Zhang
> Assignee: Buddhi Ayesha
> Labels: gsoc2017, mentor
>
> SQL support will allow those unfamiliar with Scala/Java to use Gearpump. I
> propose to build SQL layer with Apache Calcite because
> 1. It has done the hard job of parsing, translating logical plan to physical
> plan and optimizing.
> 2. It is under active development and has a great community.
> 3. It's proved to be a good solution since Apache Storm, Apache Flink and
> Apache Samza all build their Streaming SQL with Apache Calcite
> Note SQL here actually means Streaming SQL dialects supported by Calcite
> (check reference 1 and 2). Please checkout reference 3 for an example
> implementation.
> The physical plan will be translated to Gearpump high level DSL.
