当表的Schema发生变化时,FE会更新节点版本,同理SE也会更新节点版本,如果FE和SE的版本不对齐,则会出现Schema延迟。如果延迟较高,一般原因是因为SE处理慢,尤其是分区父表的DDL较多时,延迟较高,导致数据写入/查询慢,建议针对性优化DDL频率。 Lock query cost:Query加锁所耗时间,如果耗时较高,则说明Query在等锁。

如果要分析某条SQL的性能问题,通常我们要先看SQL的执行计划,看看SQL的每一步执行是否存在问题。如果一条SQL平时执行的好好的,却有一天突然性能很差,如果排除了系统资源和阻塞的原因,那么基本可以断定是执行计划出了问题。 看懂执行计划也就成了SQL优化的先决条件。这里的SQL优化指的是SQL性能问题的定位,定位后就可以...
