After having looked at what this actually is, I'm a bit disappointed. I was hopping that they wound change the various panels data API so that they would request only the new time slices; ie. instead of querying the last hour of data every minute, query the last minute every minute and reuse the previous 49 data points. But that's not what this is. Instead, you need a specific panel and a specific data source for streaming to work. :-(

This datasource doesn't require any custom panels to function. To your point though, it would be nice if grafana supported incremental time range querying out of the box, since many backends don't support streaming data.

Something we are looking at.

Problem is complicated when the query applies time series transformations such as moving averages, where requesting only incremental data can be problematic.
