Compute Real-time Visualizations using spark streaming

[Sureshv <su...@transerainc.com>]

Hi, 

 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.

Thanks,
Suresh

Simplest approach would be to push the streaming data (after the
computations) to a SQL-Like DB and then let your visualization piece pull
it from the DB. Another approach would be to make your visualization piece
a web-socket (If you are using D3JS etc) and then from your streaming
application you can push the data to the web-socket which will power the
dashboards.

Thanks
Best Regards
