@balaji.ramaswamy I would appreciate some help with connecting Dremio to Superset.
I followed the steps described in the documentation and successfully established a connection between Superset and Dremio. Reflections, Acceleration, everything works great except the “Time Grain” selection on any of the charts or tables.
It shows “0 option(s)” for every datetime/timestamp column I have… I checked the dataset and the aggregate reflection both are timestamps. I have both “original” and “day” aggregation on different columns and none of them show any option for Time Grain.
My connection is using pyodb: “dremio+pyodbc://root:XXXXXXXXXX@…/dremio”
If I use my Druid datasource, then the Time Grain options are available…
Is it some configuration I am missing on the Dremio end or maybe some extra Superset actions needed that I am missing?
It is not a problem for aggregate tables or pie/bar charts, but if I have a linechart, it is not ideal to have a datapoint for every millisecond…
Thanks in advance!
