How to get the table-name and database-name in the CDC event received from debezium kafka connect - sql-server

Question

Setup: I have CDC enabled on MS SQL Server and the CDC events are fed to Kafka using debezium kafka connect(source). Also more than one table CDC events are routed to a single topic in Kafka.
Question: Since I have more than one table data in the kafka topic, I would like to have the table name and the database name in the CDC data.
I am getting the table name and database name in MySQL CDC but not in MS SQL CDC.
Below is the Debezium source connector for the SQL Server
curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/ -d '{
"name": "cdc-user_profile-connector",
"config": {
"connector.class": "io.debezium.connector.sqlserver.SqlServerConnector",
"tasks.max": "1",
"database.hostname": "<<hostname>>",
"database.port": "<<port>>",
"database.user": "<<username>>",
"database.password": "<<password>>",
"database.server.name": "test",
"database.dbname": "testDb",
"table.whitelist": "schema01.table1,schema01.table2",
"database.history.kafka.bootstrap.servers": "broker:9092",
"database.history.kafka.topic": "digital.user_profile.schema.audit",
"database.history.store.only.monitored.tables.ddl": true,
"include.schema.changes": false,

"transforms":"addStaticField,topicRoute",
"transforms.addStaticField.type":"org.apache.kafka.connect.transforms.InsertField$Value",

"errors.log.include.messages": true,
"errors.retry.delay.max.ms": 60000,
"errors.retry.timeout": 300000
}
}'
I am getting the below output (Demo data)
{
"before": {
"profile_id": 147,
"email_address": "test#gmail.com"
},
"after": {
"profile_id": 147,
"email_address": "test_modified#gmail.com"
},
"source": {

"snapshot": false
},
"op": "u",
"ts_ms": 1556748731417,
"source_system": "source_system_1"
}
My requirement is to get as below
{
"before": {
"profile_id": 147,
"email_address": "test#gmail.com"
},
"after": {
"profile_id": 147,
"email_address": "test_modified#gmail.com"
},
"source": {
"version": "0.9.4.Final",
"connector": "sqlserver",

"table": "table1/table2"
},

}

This is planned as a part of https://issues.jboss.org/browse/DBZ-875 issue

Answer 2

Debezium Kafka-Connect generally puts data from each table in a separate topic and the topic name is of the format hostname.database.table. We generally use the topic name to distinguish between the source table & database name.
If you are putting the data from all the tables manually into one topic then you might have to add the table and database name manually as well.
