That's how the CSV Dataset works already.

I've now had a look at the docs, and AFAICS the JDBC "batch" feature
is not intended for batch loading, it seems to be intended to process
multiple different SQL statements as a single batch that either
succeeds or fails as a whole.

Just enclose the sampler in a Loop Controller, and use a function to
generate the 'random' data.
