> 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.
