Topics for meeting with Monty

  • splitting myisam so that we can build it as lightweight library
  • proxy
    • lua painful
    • lua is single-threaded, can't block on calls
    • MaxScale and ProxySQL. Both seem lower in maturity than mysqlproxy. In both, the focus is on scalability and load-balancing, and customizability is focused on rewriting queries
  • narrow table for objectId, need efficient index, need some updates, 50B rows
  • worth trying Aria?
  • joint keynote about myisam at percona mysql conf?
  • borrowing mysql developer for 2-3 years?
