Thoughts? Earlier threads about your work mentioned rescheduling threads on any event that requires a long wait (IO, row lock, ...). Is that part of your patch? For example, how does Drizzle with this patch behave when the pool size is 8 and 8 sessions block in InnoDB on the auto increment lock for a table? -- Mark Callaghan [email protected] _______________________________________________ Mailing list: https://launchpad.net/~drizzle-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~drizzle-discuss More help : https://help.launchpad.net/ListHelp
