Subject Re: SQL support to Gearpump
Date Tue, 28 Mar 2017 14:49:43 GMT
Hi Venkat,

Thanks for your participation. This is Manu, mentoring this project.
Frankly, I'm new in this area myself and mostly I've been following how
other streaming framework has done so. For example,

These incomplete codes,
what I've tried for this task some while ago, which could be a start point
for you.
  - In QueryExecutor.scala
you can see how a sql string is parsed and translated into tree of
`RelNode` in Calcite.
  - StreamRel
its subclass should `translate` the node into corresponding Gearpump

Looking forward to your proposal ;)

Hello everyone,

I am venkat, I would like to work on adding SQL support for Gearpump for
this Google Summer of Code. Currently I am preparing my project proposal.

I am not pretty clear about converting logical plan of apache calcite in to
jobs on Gearpump?

Anyone has any ideas on this topic.

Looking forward to hear from you guys.
