MySQL is holding a webinar on Scale-Out and Replication Best Practices for High-Growth Businesses on June 20. Knowing how to scale databases should certainly be in the toolkit of every data engineer. Seems like the webinar will have a strong focus on Web 2.0 architectures (where MySQL is strong), and emphasize the use of master-slave replication to handle Web 2.0 data usage patterns (i.e. orders of magnitude more reads than writes).
Update: Looks like the link is broken. I’ll update here when the page is back up or if there’s any new info on the seminar.
Update: Found a different link that seems to work.
