Alexander "Sasha" Pachev has worked extensively with Linux since 1997 on corporate web servers, database servers, and desktops. Around that time he started working with the MySQL database, which led him to joining the MySQL Development Team in 2000. He wrote and maintained the MySQL replication module up until 2002 and authored "MySQL Enterprise Solutions" (Wiley). Sasha is also an elite marathon runner and has developed several software tools of interest to runners.
"Understanding MySQL Internals provides a very good introduction to the internals of MySQL Server. Being a former member of the MySQL development team from 2000 to 2002 and the original developer of replication in MySQL, Pachev holds a lot of expertise and credibility...That said, if you are a programmer wanting to customize MySQL for specific use, a DBA wanting to optimize your queries or truly understand the inner workings, or if you just like to open the box and see how things work, then Understanding MySQL Internals is your ticket to the big top."
