Hi,
I am looking for a way to get only the very last row of data from a Druid cube into a Superset dashboard. Actually the data set is a time series and in a dashboard I want to present the very last state, so the row with the highest timestamp (' ts2' ). On the Druid side I made sure the data is not aggregated (by including the ts2 field as a dimension field)
My Druid datasource has the following fields:

So I thought if I put the query like this (granularity ALL, all fields in the NOT GROUPED BY box):

it should return the atomic, non aggregated rows and if I sort by the time stamp 'ts2' I should be able to return only the last row of data:
But it doesn't. Looking at the Druid query definition Superset creates out of this it makes sense:

{
"queryType": "timeseries",
"intervals": "2018-03-20T14:43:23+00:00/2018-03-27T14:43:23+00:00",
"granularity": "all",
"postAggregations": [],
"aggregations": [
{
"type": "count",
"name": "count"
}
],
"dataSource": "webmetricsIIts2"
}
None of my requested dimension columns of NOT GROUPED BY input box are in the query def.
Anyone got an idea how to do this?
