首先,我们知道,在 MySQL 5.7 中给表加字段属于 ONLINE DLL ,会重建表,但允许并发 DML(PS:MySQL 8.0 加字段不需要重建表) 由于MySQL 采用的是索引组织表(IOT),表上的索引当然也需要重建,由于采用了 ALGORITHM=INPLACE 的方式,允许并发 DML 在MySQL 5.7 中,对索引有一个优化,即 Sorted Index Builds ,会在创...

--safe-slave-backup:这个选项是要和--slave-info 结合使用的。发起备份时,会暂停 SLAVE 的 SQL Thread,确保备份时没有临时表打开,保证数据的一致性。备份结束后,SQL 线程会自动启动。如果 Slave_open_temp_tables 在--safe-slave-backup-timeout 秒后未变成零,则备份失败。
如果出现Error: failed to execute query LOCK TABLES FOR BACKUP: Access denied; you need (at least one of) the RELOAD privilege(s) for this operation,则表明用于备份的账号权限不足。为了执行备份任务,至少需要以下权限:RELOAD、LOCK TABLES、REPLICATION、PROCESS。在 MySQL 8.0中,还需具备BACKUP_ADMIN权限...
