[ #18652 ]

Beware of adding insert triggers in Oracle. They can KILL performance.

Note: A mere 30,000 row insert caused an IO error.

I was just having this conversation today, but about PostgreSQL. It was all conversation, no facts. But I do wonder whether the participants were coloured by experience of other databases. I'll have to measure postgres to see how badly triggers affect insert performance there.

  To be fair, I think our IO limits are sucky and we definitely need to have a conversation with the DBA because we're hitting IO limits on some other updates that don't involve the trigger (which we dropped btw). But, we'll see.
