> 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.
