Apache Doris Flink Connector

Apache Doris Flink Connector is a tool that allows users to connect Apache Flink to Apache Doris. Apache Doris is a distributed analytical database that supports real-time analysis of large-scale data, while Apache Flink is an open-source stream processing framework that allows for real-time data processing. The connector enables users to read data from Doris into Flink, perform real-time analysis on the data, and write the results back to Doris. This integration provides users with a powerful tool for real-time data analysis and decision-making. The connector is open-source and available on Github for developers to contribute and enhance its functionalities.

flink doris connector 写 apache doris 依赖 flink checkpoint 吗

是的，Flink Doris Connector 写入 Apache Doris（原名 Apache DorisDB）同样依赖 Flink 的 checkpoint 机制。Checkpoint 是 Flink 在运行过程中对状态进行持久化的机制，它可以保证在出现故障时能够恢复到最近一次的状态。在 Flink Doris Connector 中，写入 Apache Doris 的数据也会被视为 Flink 状态的一部分，因此需要依赖 Flink 的 checkpoint 机制来保证数据的一致性和可靠性。

org.apache.doris.flink.exception.DorisException: Load status is Label Already Exists and load job finished, change you label prefix or restore from latest savepoint!

这个异常是Apache Doris Flink Connector抛出的。它表示加载作业的状态已经是“Label Already Exists”，并且加载作业已经完成。这可能是由于您的标签前缀已经存在所致。您需要更改标签前缀或者从最新的保存点进行恢复。请注意，这个异常信息中提到了“DorisException”，这意味着出现了Doris的异常，可能需要进一步的排查和处理。
