【 TiDB 使用环境】生产\测试环境\ POC
【 TiDB 版本】
4.0.7
cdc server 以及cdc cli均为4.0.7
【遇到的问题】
基于时间点的同步，新建的复制任务会出现卡住的情况，tso不往前推进
【复现路径】做过哪些操作出现的问题
update mysql.tidb set VARIABLE_VALUE= '24h' where VARIABLE_NAME= "tikv_gc_life_time" ;
br备份，作完整的数据库恢复，根据br备份文件metabackup中的commitTS作为cdc的tart-ts
./cdc cli changefeed create --pd=http://192.168.0.5:2379 --sink-uri=“mysql://test:test@192.168.0.1:4000/” --changefeed-id “test-2018” --config=changefeed.toml --start-ts=433921993657810984 --sort-engine=unified
复制任务不往前推进，暂停之后在启动也不行
