Subject [Query] Columnar transformation without Structured Streaming
Date Thu, 29 Mar 2018 12:41:14 GMT

I started my Spark Streaming journey from Structured Streaming using Spark
2.3, where I can easily do Spark SQL transformations on streaming data.

But, I want to know, how can I do columnar transformation (like, running
aggregation or casting, et al) using the prior utility of DStreams? Is
there a way? Do I have to use map on RDD and go about the complex
transformative steps? Or can I convert a DStream into DF and do the job?

Appreciations in advance!
