Also depends what you are doing. The first person to do a read causes a TABLE LOCK. No row level locking. MySQL way to assure the data you see back is what it really is.

But MySQL does have one nifty little feature, you can load tables into memory exclusively. Great for speed, terrible for recovery. But at least you don't have to issue a truncate, just kill the database, it does it for you.

If there's only one user accessing it, yes.

  1. It's blindingly fast as a single user database, faster then oracle.

Really? Even with a 30 million record table?

I read few articles in Linux magazine and had it installed on my box for a while and here are my impressions:

  1. It's blindingly fast as a single user database, faster then oracle.
  2. It uses more or less standard SQL minus all the unnecessary functions like substr, decode, nvl and alike which nobody ever uses anyway (evil grin).
  3. It's small. You can have both software and a small database within 150M
  4. I didn't learn how to do recovery. It doesn't have hot backups. You have to shut it down to make a sensible backup.
  5. It's easy to configure and doesn't have too many things to set up.

Allegedly, the present version (I did my dirty work back in August 2001) can use
Perl as a scripting language, I don't know whether DBI/DBD is needed for that and
it can cope with committs and rollbacks.
