By Dashboard I mean a Visualization backed by a data but the main point here is how can we make real time latency requirements using Zeppelin

See the attached screenshot. You might say it refreshes the entire note, not just selected cells, that is true. -Vinay On Wed, Aug 24, 2016 at 7:30 PM, Corneau Damien < cornead...@gmail.com > wrote: I was referring to this documentation: https://zeppeli n.apache.org/docs/0.6.1/ displaysystem/back-end-angular .html On Thu, Aug 25, 2016 at 11:19 AM, kant kodali < kanth...@gmail.com > wrote: I dont know how angular works moreover I don't understand why we should be tied to certain framework?

And a pre-built solution is never really as flexible as a customized dev. I don't see how we can create a generic component. Unless we decouple the data receiver component from the display component and make them pluggable.

In this case the only solution for you is: 1) use %angular interpreter 2) import a JS library in a paragraph and do some JS coding to open a web-socket channel to the data source so that the new updates can be pushed directly to the paragraph On Wed, Aug 24, 2016 at 1:15 PM, kant kodali < kanth...@gmail.com > wrote: Hi, Sure, I can either write it to HDFS or Cassandra but not HBASE since we don't use it but how about constant updates? you know what I mean?

You could then use Zeppelin's Phoenix interpreter to read that data. Not sure if this fits your requirements.

If so, where would be the best place to write the latest results? Thanks, Kant
