>
> examples.simple.RandomBatchWriter takes a command line arg for how many
> rowids to write.
> In the functional tests, this arg is used to coordinate a number of expected
> reads with teh examples.simple.RandomBatchReader example.
> the reader implementation ensures that it generates the passed number of
> query rows, but the write just makes num attempts at creating random rowids.
> For a small number of goal rows and a large range (like the examples used for
> testing bloom filter speeds early in the examples integration test), this
> works fine.
> For a larger number of goal rows (like the examples used to just write/read
> 10k rows later in the examples integration test), collisions in the selected
> row ids will cause the writer to actually generate fewer than the expected
> number. That, in turn, will cause the attempted read integration test to
> fail.
