---------------------------------
Summary: Add schema info to output of Kafka sink
Key: FLINK-36611
URL: https://issues.apache.org/jira/browse/FLINK-36611
Project: Flink
Issue Type: New Feature
Components: Flink CDC
Affects Versions: cdc-3.3.0
Reporter: LvYanquan
Fix For: cdc-3.3.0
Currently, the output of Kafka sink in debezium format looks like this:
{code:java}
{
"before": {
"id": 4,
"name": "John",
"address": "New York",
"phone_number": "2222",
"age": 12
},
"after": {
"id": 4,
"name": "John",
"address": "New York",
"phone_number": "1234",
"age": 12
},
"op": "u",
"source": {
"db": null,
"table": "customers"
}
} {code}
It contains record data with full before/after and db info, but schema info
wasn't included.
However, In some scenarios, we need this information to determine the type of
data. For example, Paimon's Kafka CDC source requires this type information,
otherwise all types are considered String, refer to
[https://paimon.apache.org/docs/0.9/flink/cdc-ingestion/kafka-cdc/#supported-formats.]
Considering that this will increase the data load, I suggest adding a parameter
to configure whether to enable it.
