Dashboard streaming analytics filtering
Is it possible to subscribe to a table with filtering through KX Dashboards streaming data source? .u.sub can allow for filtering, and I would like to filter the subscription on KX Dashboards side too and I’m wondering what I need to change. I.e. do I need to change .u.snap, and where can I put in the filter criteria as a parameter?

Hi,
Hopefully I can help answer your question below here:
1. Overview of Streaming
This is a very useful video about how Streaming queries are set up : KX Dashboards | Streaming Data – YouTube
2. Demo Streaming with Filtering
If you have KX Dashboards installed (https://code.kx.com/dashboards/gettingstarted/)
Then navigate to the “Demo Stream” Dashboard, there is a build in example where we pass in a parameter to the streaming model that filters the returning data set .
Therefore:
1. On load – we subscribe to the using the default filter
2. If we change the viewstate, we then unsubscribe and the re-subscribe using the new filter
