> I haven't reproduced it with a test yet but, from code inspection, if CQL 
> rows are larger than {{batch_size_fail_threshold_in_kb}} and this parameter 
> cannot be changed, then data import will fail.
> Users can control the batch size by setting MAXBATCHSIZE.
> If a batch contains a single statement, there is no need to use a batch and 
> we should use normal inserts instead or, alternatively, we should skip the 
> batch size check for unlogged batches with only one statement.
