flinkcdc kafka怎樣進行窗口操作

Flink CDC Kafka 是一個用于從 Kafka 中捕獲變更數據并將其流式傳輸到 Flink 應用程序的庫。要在 Flink CDC Kafka 中執行窗口操作，您需要遵循以下步驟：

1. 添加依賴項：首先，確保在 Flink 項目中添加了 Flink CDC Kafka 連接器依賴項。在 Maven 項目的 pom.xml 文件中添加以下依賴項：

<dependency>
  <groupId>com.ververica</groupId>
  <artifactId>flink-connector-kafka-cdc</artifactId>
  <version>1.14.0</version>
</dependency>

2. 創建 Flink 應用程序：創建一個 Flink 應用程序，并配置 Kafka CDC 連接器以從 Kafka 主題中捕獲變更數據。例如：

import org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer;
