Flink的 CTAS 目标库为starrocks,为什么报错呢?语句时照抄 https://help.aliyun.com/zh/emr/emr-on-ecs/user-guide/use-the-ctas-and-cdas-statements-of-realtime-compute-for-apache-flink-to-synchronize-data-from-an-apsaradb-rds-for-mysql-instance-to-a-starrocks-cluster?spm=a2c4g.11186623.0.0.30127e8dDcfzkb 的这里
报错:org.apache.flink.table.api.ValidationException: SQL validation failed. CREATE TABLE ... AS TABLE ... statement requires target catalog 'vvp' (VvpCatalog) implements org.apache.flink.table.catalog.CatalogTableProvider interface.
Hint: Please refer the document and use another catalog that supports schema evolution as the target catalog.

Flink的CTAS(Create Table As Select)目标库为StarRocks时报错,可能有以下原因:
版本兼容性:请确保您使用的Flink版本与StarRocks的版本兼容。不兼容的版本可能导致无法正常通信或执行操作。
配置错误:检查您的Flink作业配置是否正确,包括连接字符串、用户名、密码等,确保这些配置能够正确连接到StarRocks。
权限问题:确保Flink作业拥有足够的权限在StarRocks上执行CTAS操作。如果没有相应的权限,操作可能会失败。
语法错误:检查您的CTAS语句是否符合StarRocks的语法规范。例如,如果您使用了CDAS(Create Database As Select)语句,需要确保源表和目标表的结构匹配,并且可以使用including table语法来选择部分表进行操作。
资源限制:可能是由于资源限制,如内存不足或网络带宽限制,导致数据处理过程中出现问题。
数据格式问题:确保数据的格式与StarRocks中的表结构相匹配,不匹配的数据格式可能导致写入错误。
网络问题:检查网络连接是否稳定,不稳定的网络可能导致数据传输中断或超时。
系统错误:可能是StarRocks本身的问题,比如服务不可用、系统维护等。
综上所述,为了解决这个问题,您可以从上述几个方面进行排查和调整。如果问题依然存在,建议查看Flink的日志文件以获取更详细的错误信息,或者联系StarRocks的技术支持寻求帮助。
