I believe rrdtool has a maximum resolution of 1 update per second per
file. The amount of disk I/O required to do a million samples per second,
even if rrd's format did support it, are pretty astronomical.
What you probably want is some sort of entirely in-memory database,
I'm not sure what product to suggest.
