PyFlink支持读取Kafka的数据写入MongoDB吗？

是的，PyFlink支持从Kafka读取数据并将其写入MongoDB。您需要使用PyFlink的Kafka connector和MongoDB connector来实现此功能。以下是一个简单的示例代码，它演示了如何使用PyFlink从Kafka读取数据并将其写入MongoDB:

from pyflink.common.serialization import SimpleStringSchema
from pyflink.connectors import KafkaSource, MongoDBSink
from pyflink.datastream import StreamExecutionEnvironment

env = StreamExecutionEnvironment.get_execution_environment()
kafka_source = KafkaSource(
    topic="my-topic",
    properties={"bootstrap.servers": "localhost:9092"},
    serializer=SimpleStringSchema(),
    deserializer=SimpleStringSchema()
)
mongodb_sink = MongoDBSink(
    uri="mongodb://localhost:27017/mydb",
    database="mydb",
    collection="mycollection",
    mq_configs={"producer.ack.mode": "manual", "producer.max.block.ms": 60000}
)
datastream = env.add_source(kafka_source)
datastream.add_sink(mongodb_sink)
env.execute("PyFlink Kafka to MongoDB Example")
