Hi!
I use the program testReadPerf to do some benchmarking on NDB Cluster
and when I tried to make sense of the timings I get, I realized that I
could use some insight on what that thing is doing in it's individual tests.
I'm wondering what exactly the different tests in this benchmark are.
From the MySQL reference manual I know what serial/batch pk and
serial/batch uniq index do, but I'm curious what "eq-bound" means and
what kind of index is used in the "index eq-bound" and "index range" tests.
In essence the tests "index eq-bound", "index range" and "index ordered"
are some kind of mystery to me.
It would be really nice if someone here could explain these things.
(maybe with some mysql query like example, if that is possible)
Thanks
Dirk
