> Current list of valid floor units that can be pushed as valid floor unit is missing Quarters, something that Druid can actually do. 
> This is a performance bug.
> For instance query 
> {code} 
> SELECT floor_year(`__time`), max(added), sum(variation)
> FROM druid_table_1
> {code}
> Is currently planned as 
> {code} 
> {"queryType":"scan","dataSource":"wikipedia","intervals":["1900-01-01T00:00:00.000Z/3000-01-01T00:00:00.000Z"],"virtualColumns":[{"type":"expression","name":"vc","expression":"\"__time\"","outputType":"LONG"}],"columns":["vc","added","variation"],"resultFormat":"compactedList"}
> {code}
> And it can be optimized to 
> {code}
> {"queryType":"timeseries","dataSource":"wikipedia","descending":false,"granularity":"quarter","aggregations":[{"type":"doubleMax","name":"$f1","fieldName":"added"},{"type":"doubleSum","name":"$f2","fieldName":"variation"}],"intervals":["1900-01-01T00:00:00.000Z/3000-01-01T00:00:00.000Z"],"context":{"skipEmptyBuckets":true}}
> {code}
