已在 us-east-1 区域中创建一个集群[集群名称:staging-dax-cluster.ckbrjt.clustercfg.dax.use1.cache.amazonaws.com]。当我尝试使用集群时出现以下异常。
支持的通用库日志记录已弃用。切换到 slf4j 后端。 不再支持 Cloud Watch 附加程序。使用 stdOut 附加器或 SLF4J 支持。

最佳答案
DAX 无法识别用于管理表的 DynamoDB 操作，在您的情况下为“describeTable”。支持读取和写入操作。请参阅documentation了解详细的 API。
关于java - 无法通过 DAX 集群访问 dynamodb 表，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46823189/
