Initial number of streams. If unset or 0, we will
provide a value of streams so as to produce reasonable throughput. Must be
non-negative. The number of streams may be lower than the requested number,
depending on the amount parallelism that is reasonable for the table and
the maximum amount of parallelism allowed by the system.
