【 TiDB 使用环境】生产环境 /测试/ Poc
生产环境，TIDB部署在k8s当中，TiDB实例大概有表5000～10000张，但是配置TiCDC同步的表只有150张左右，整个TiDB的数据量不大，只有不到10G。
目前整个环境还在测试当中，所以配置了TiCDC的表，也都没有什么流量，一张表的数据量也就几十万；整个环境的DDL操作比较频繁，会经常有truncate table操作；
【 TiDB 版本】
TiDB 5.4
【复现路径】做过哪些操作出现的问题
通过TiCDC 的openapi 创建changefeed失败，总是遇到etcd 超时的问题
【遇到的问题：问题现象及影响】
curl -X POST http://127.0.0.1:8301/api/v1/changefeeds -d ‘{“changefeed_id”:“k1”,“sink_uri”:“kafka://broker-kafka-test-az1-0.jvessel-open-hb.jdcloud.com:9092/tidb_version_test?protocol=canal-json&kafka-version=2.4.0&max-message-bytes=1073741824”, “filter_rules”:[“test.test1”]}’
返回 CDC:ErrPDEtcdAPIError]etcd api call error: context deadline exceeded
不是偶尔出现，几乎是100%的出现，且出现该错误的时候，http请求都是在12～14秒左右返回
同时通过cdc cli 创建就不会有问题
【资源配置】
TiCDC 配置 8C，16G；
/cdc server --addr=0.0.0.0:8301 --advertise-addr=tidb-test-ticdc-0tidb-test-ticdc-peer.tidb-test.svc:8301 --gc-ttl=86400 --log-file=/tmp/cdc_data/log/cdc.log --log-level=info --pd=http://tidb-test-pd:2379
