无法通过 DAX 集群访问 dynamodb 表

Question

在 us-east-1 区域创建了集群 [cluster name : 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。

支持的公共库日志记录已弃用。切换到 slf4j 后端。 Cloud Watch appender 不再受支持。使用 stdOut appender 或支持的 SLF4J。

DAX 无法识别用于管理表的 DynamoDB 操作，在您的情况下 "describeTable"。支持读写操作。有关详细 API，请参阅 documentation。
