Kafka returning same set of records even after full records fetched from the table

Description

Kafka returning same set of records even after full records fetched from the table

• Iam using connector api for producer and consumer code in separate file to consume the message
• Once full data is fetched from table again data is flowing in loop never stopping

Producer config:
payload = {
"name": "jdbc-postgres-connector-test3",
"config": {
"connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
"mode": "bulk",
"incrementing.column.name": "_id",
"topic.prefix": "test",
"connection.password": "xxxxx",
"tasks.max": "1",
"batch.max.rows": "10000",
"connection.user": "xxxxx",
"connection.url": "jdbc:postgresql://xx.xx.xx.xx/test",
"key.converter": "org.apache.kafka.connect.json.JsonConverter",
"value.converter": "org.apache.kafka.connect.json.JsonConverter",
"key.converter.schemas.enable": "false",
"value.converter.schemas.enable": "false",
"enable.idempotence": "true",
"acks": "all",
"poll.interval.ms": "-1",
'query': 'SELECT * FROM employee'
}
}

Consumer code:

from confluent_kafka import Consumer, KafkaError

conf = {
'bootstrap.servers': 'localhost:9092',
'group.id': 'test-consumer-group',
'auto.offset.reset': 'earliest',
'enable.auto.commit': False,
'enable.partition.eof': True,
'compression.type': 'gzip',

}

consumer = Consumer(conf)
topics = ['test']

consumer.subscribe(topics)
try:
while True:
msg = consumer.poll(1)
if msg is None:
continue
if msg.error():
if msg.error().code() == KafkaError._PARTITION_EOF:
consumer.close()
break
else:
print(msg.error())
break
try:
data = msg.value().decode('utf-8')
with open(f'data.txt', 'a') as file:
file.write(data + '\n')
consumer.commit(asynchronous=False)
except Exception as e:
print(f"Error processing message: {e}")
consumer.close()
except KeyboardInterrupt:
pass
finally:
consumer.close()

Required is once all data consumed or produced stop send the data or receiving the data as my scenario is not for real-time data.
