kv doesn't cut my use case. After import I'm running several queries to remove unwanted data. I was shortly contemplaiting filtering while I was importing but (a) I couldn't really handle relationships - hence two distinct steps - remove and remove orphans, and (b) even if I could it's really much cleaner code having a single simple function to import a table, and then having a clean one liners to remove weed. And (c) I need sql queries later on.
