MySQL, Oracle and others implement read-ahead threads to simulate async IO
I always believed that Oracle used async file I/O. Not that I've seen their
code, but I'm fairly sure they funded the addition of kernel aio to Linux
a few years back.
But....Oracle comes from a time long ago when threads and decent
filesystems didn't exist, so some of the things they do may not be
appropriate
to add to a product that doesn't have them today.
Now...network async I/O...that'd be really useful in my world...
