支持黑洞引擎(ENGINE = BLACKHOLE;)。 支持DDL 执行所用的默认算法(inplace/instant), 可以通过 innodb_alter_table_default_algorithm 参数来指定。 性能优化 大事务提交 binlog 优化:支持大事务的日志先写入临时文件,然后将临时文件重命名为下一个 binlog,以减少大事务提交阻塞其他事务的时间。

A:不一定,例如增加全文索引的操作,这个操作是inplace的,但是会阻塞增删改查操作,因此不是Online DDL。应该说:Online DDL一定是inplace的,但是inplace方案进行的操作,不一定是Online的。 Q4、某个表的大小是1TB,进行alter table A engine=Innodb之后,表的空间没有缩小,反而增大了一点,这是为什么?
1、ALTER TABLE操作未导致主键索引记录的事务信息和回滚指针发生变化 2、新增C2列导致"行偏移量”新增一个字节来表示C2是否为NULL,01表示为NULL。 3、新增C2列未导致“记录列信息”发生变化,即"记录列"中无C2列对应的存储空间,因为C2列为NULL。 测试2:ALTER TABLE测试2 ...
