flinkcdc kafka怎样进行窗口操作

Flink CDC Kafka 是一个用于从 Kafka 中捕获变更数据并将其流式传输到 Flink 应用程序的库。要在 Flink CDC Kafka 中执行窗口操作，您需要遵循以下步骤：

1. 添加依赖项：首先，确保在 Flink 项目中添加了 Flink CDC Kafka 连接器依赖项。在 Maven 项目的 pom.xml 文件中添加以下依赖项：

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

2. 创建 Flink 应用程序：创建一个 Flink 应用程序，并配置 Kafka CDC 连接器以从 Kafka 主题中捕获变更数据。例如：
