Schwartz is a co-author of High Performance MySQL, 2nd ed. (published 2008, O'Reilly). He developed and maintains Innotop, an open source interactive monitoring tool for MySQL and InnoDB, and the Ma'atkit toolkit for MySQL, which includes tools for:

  • query profiling
  • duplicate key checking
  • table checksum and sync
  • parallel dump and restore
  • replication heartbeat
  • replication delay
  • replication slave automatic restarting
  • replication pre-fetching, to warm slave caches
  • a tree-formatted query analyzer
  • deadlock logging
  • archiving data
  • showing permissions for multiple database users
  • an analog to the Unix "find" command, that can test and perform actions on database objects

Schwartz won MySQL's 2008 MySQL Code Contributor of the Year Award for Ma'atkit. He has also released a set of templates to monitor MySQL under Cacti.
