8.5 版本的 cdc 同步延迟问题

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

很高，就是这个情况，延迟一直增高，但是数据是有写入的，只是慢

[WalterWj (王军 - PingCAP)]

你这个截图太大了。看不清。
changefeed checkpoint lag 和 changefeed resolved lag:

1. 如果都大，说明瓶颈在上游
2. 如果前者很小，后者很大说明瓶颈在下游。

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

前者比较大，我现在改成 8.5.4 的再试下，刚才测试新的集群 8.5.4 的同步是正常的

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

更新到v8.5.4 了，还是有问题

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

看 cdc日志好像也是正常的

上游有长事务么？

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

有，但是不多，现在是低峰期，之前的 6.5.9 是正常同步的

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

8.5.4 的还是有延迟，在慢慢上涨，只要业务量一上来延迟就逐渐增长
下面是我关于 cdc 的配置，有没有可以优化我这个场景的，insert 跟 update 比例是 1:3，在高峰期的并发是每秒 5000 条左右的数据

感觉就是这个Sink Event Row Count / s上不去的原因，关闭了batch-dml-enable，刚开启的时候，有一段时间正常的，后面又开始延迟缓慢上升

[porpoiselxj]

我怎么感觉你说反了， resolved lag 小， checkpoint lag 大， 才说明瓶颈在下游吧

[WalterWj (王军 - PingCAP)]

没说反。

[porpoiselxj]

@WalterWj

很大说明瓶颈在下

两个指标的关键差异

监控范围不同

• Checkpoint lag：监控整个复制链路的端到端延迟
• Resolved lag：仅监控TiCDC内部处理的延迟

问题定位价值

通过对比这两个指标，可以精确定位性能瓶颈：

1. Checkpoint lag高，Resolved lag正常：

• 问题出现在下游写入环节
• 下游数据库写入延迟高，阻塞TiCDC及时复制数据2
• 解决方案：优化下游写入速度

2. 两个指标都高：

• 问题出现在TiCDC内部处理
• 通常是上游QPS过高，超过TiCDC节点处理能力（单节点约60K QPS）1
• 解决方案：增加TiCDC节点数量进行横向扩展3

[WalterWj (王军 - PingCAP)]

指标哪里获取的，应该有问题。

[porpoiselxj]

根据我的经验来看，一般都是 Checkpoint lag > Resolved lag, 以上的的指标是ai.tidb的答复

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

这个冲突检测花了很长时间，不知道是不是跟这里有关系

[纯白镇的小智 (Ti D Ber Qm Qja01 M)]

同步延时增长不仅和源端 CDC 有关，目标端的处理能力也会影响 ACK 反馈速度

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

没辙了
我们之前的架构是 6.5.9 同步到 8.1.1，集群之间的网络延迟有 170ms

然后现在部署新架构新版本的，集群直接延迟一样都是 170ms 左右，cdc 任务的延迟增长很快
然后我把新架构版本改成跟之前一样的，也还是很高的延迟，不知道问题出在哪里

[异乡的大人 (Ti D Ber 2 Qs S2z Ws)]

这个问题还没有解决呀

[TiDBer_Ejh0eCXc]

没遇到过

[TiDBer_Jack (Ti D Ber Mk Wfi W Zy)]

还没有
