Sergei Ok, mysqlimport uses LOAD DATA INFILE.
Yes, but they are simply convenient shortcuts to
myisamchk --keys-used=0 -rq
You can enable/disable keys from command line in 3.23.
Ok, what is the suggested usage?
create
MySQL - spam bypasser
myisamchk --keys-used=3D0 -rq
You can enable/disable keys from command line in 3.23.
While that would disable the key before the load,
how do I re-enable them afterwards?

I'm trying to understand the most efficient load sequence
possible.
I've got 2 large tables. Each is about 50 million rows,
taking about 20GB of disk space. My disk is accessed
via fibre channel, and can read/write about 40 MB per
second.
My system is a dual PIII 850, running Linux 2.4.2-2smp

Hi Barry,
It is, indeed, faster to load the data then create the indexes.
Instead of 'disable' and 'enable', you could try:
- ALTER TABLE DROP index (or drop the table and create it without indexes.)
- load your data
- ALTER TABLE ADD index

I've always thought it would be great if there was a way to drop an object but
keep the meta data so I can recreate objects without having to store the ddl
somewhere.

Hi back.
Why do you need RAID ? Are you using ext2fs ?
With 2.4.2 you can use reiserfs, which does not have 2GB file limit.
Using ext2fs right now. Heard a lot of reiserfs
