根据数据库 limit 或者 top ；

limit：10

# pt_archiver:6555 620 get first sql: SELECT /*!40001 SQL_NO_CACHE */ `id`,`name` FROM `my_database`.`test` FORCE INDEX(`PRIMARY`) WHERE (1=1) ORDER BY `id` LIMIT 10
# pt_archiver:6556 620 get next sql: SELECT /*!40001 SQL_NO_CACHE */ `id`,`name` FROM `my_database`.`test` FORCE INDEX(`PRIMARY`) WHERE (1=1) AND ((`id` >= ?)) ORDER BY `id` LIMIT 10
# pt_archiver:6557 620 del row sql: DELETE FROM `my_database`.`test` WHERE (((`id` >= ?))) AND (((`id` <= ?))) AND (1=1) LIMIT 10
