#define PT_WAIT_WHILE(pt, cond) PT_WAIT_UNTIL((pt), !(cond)) #define PT_SCHEDULE(f) ((f) < PT_EXITED) PT_WAIT_WHILE是当条件cond成立时,一直阻塞。PT_WAIT_UNTIL是一直阻塞,直到condition成立。 PT_SCHEDULE(f)判断进程执行实体函数f是否已经退出或者执行完毕。 最后展开为: PT_WAIT_UNTIL((pt...

By default, pt-stalk tool watches MySQL forever until the trigger occurs, then it collects diagnostic data for a while, and sleeps afterwards to avoid repeatedly collecting data if the trigger remains true. The general order of operations is: while true; do if --variable from --function > ...
It is possible, therefore, for a client that issues an INSERT LOW_PRIORITY statement to wait for a very long time. LOW_PRIORITY affects only storage engines that use only table-level locking (such as MyISAM, MEMORY, and MERGE). 另外,用过 pt-osc 的朋友应该都了解,在并发比较高的环境下改...
