  • Mysql slave server-id selection (www.semicomplete.com)
    Two slaves with the same server id will replicate successfully, but when they reach the end of the master's binary log, something freaks out and forces them to disconnect. This causes both slaves to reconnect, sync (no data needed), and have the connection die off quickly again. The result of this is rapid connection/disconnection by both slaves driving the load to 1+ on both slaves, and to around .3 on the master even in a completely idle system. This is bad. Therefore, server id collisions are bad.

Hi, I'm Aaron Parecki, Director of Identity Standards at Okta, and co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and participate in the OAuth Working Group at the IETF. I also help people learn about video production and livestreaming. (detailed bio)

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
