Hi,
原问题中 String 变量 kafka 和 mysql 赋值反了, 以及能提供下所使用的 flink 版本吗, 我使用 1.16.1 没有复现此问题
payload
{
"before": {
"rowid": "f251af39-1a95-4d6f-b4cb-cdf93d5d1b6d",
"63f73b332e77497da91286f0": "Jerry",
"63f73b3f2e77497da91286fb": "mobile number",
"63f73b3f2e77497da91286fc": "telephone number"
},
"after": null,
"source": {...},
"op": "d",
"ts_ms": 1677342340042,
"transaction": null
}
flink sql
