Subject Compute Real-time Visualizations using spark streaming
Date Fri, 02 Oct 2015 11:47:35 GMT

 I am new to Spark and I would like know how to compute (dynamically)
real-time visualizations using Spark streaming (Kafka).

Use case : We have Real-time analytics dashboard (reports and dashboard),
user can define report (visualization) with certain parameters like, refresh
period, choose various metrics (segment variables & profile variables). 

We should compute only visualizations those are in use (users are accessing)
with events coming from kafka streams using Spark streaming. 

Solution : One way of doing is compute visualizations for every incoming
message and write back into result streams and application which consume the
processed data/result streams. 

I would like to know is there any better approach? Please advice me here.
