Description
File: /release-8.1/ticdc/ticdc-open-protocol.md
- [partition=0] [key="{"ts":415508881418485761,"scm":"test","tbl":"t1","t":1}"] [value="{"u":{"id":{"t":3,"h":true,"v":3},"val":{"t":15,"v":"ZGQ="}}}"]
Log11 是 UPDATE test.t1 SET val = 'dd' WHERE id = 3; 语句产生的日志，它是更新的; 为什么 value 的对象中没有出现 "p":{"id":{"t":3,"h":true,"v":3},"val":{"t":15,"v":"Y2M="}}
参考：https://docs.pingcap.com/zh/tidb/stable/ticdc-open-protocol#row-changed-event
Update 事件，输出新增的行数据 ("u") 以及修改前的行数据 ("p")。
