There's one catch with batched inserts: if your CLI tool fails half way through you could end up with a partially populated table - since a bunch of batches will have succeeded first.

If people care about that kind of thing they could always push all of their inserts to a table called _tablename and then atomically rename that once they've uploaded all of the data (assuming I provide an atomic-rename-this-table mechanism).
