Buddhi Ayesha commented on GEARPUMP-217:
----------------------------------------

Dear Manu,

I am a final year undergraduate of Computer Science & Engineering, University of Moratuwa,
Sri Lanka.

I agree with your proposal and also went through the reference documents given here. I have
prior experience working with streaming queries and open-source projects during my internship.

I would like to contribute to this project in GSoC 2017 and want to know more about the scope
of this project. 

Thank you.

> 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.
