Colin Dellow	6648ff5968	add string == row group filter ... For the statscan census set filtering on `== 'Dawson Creek'`, the query goes from 980ms to 660ms. This is expected, since the data isn't sorted by that column. I'll try adding some scaffolding to do filtering at the row level, too. We could also try unpacking the dictionary and testing the individual values, although we may want some heuristics to decide whether it's worth doing -- eg if < 10% of the rows have a unique value. Ideally, this should be like a ~1ms query.	2018-03-15 20:40:21 -04:00
