> Currently there exists some projects like Pig On Storm, SQL on storm (Squall, 
> SQLstream) that can query over streaming data, but for Spark Streaming, it is 
> a blank area. It will be a good feature to add streaming supported SQL to 
> Spark SQL.
> From semantic perspective, DStream is quite alike RDD, they both have join, 
> filter, groupBy operators and so on, also DStream is backed by RDD, so it is 
> transplant-able and reusable from existing spark plan.
> Also Catalyst has a clear division for each step, we can fully use its parse 
> and logical plan analysis steps,  with only different physical plan.
> So here we propose to add streaming support in Catalyst.
