Question

在us-east-1地区创建了一个群集[cluster name : staging-dax-cluster.ckbrjt.clustercfg.dax.use1.cache.amazonaws.com]。当我尝试使用群集获得以下异常时。

不推荐使用支持的常见lib日志记录。切换到slf4j后端。不再支持Cloud Watch appender。使用stdOut appender或SLF4J支持。

DAX不会识别用于管理表的DynamoDB操作，在您的情况下＆＃34; describeTable＆＃34;。支持读写操作。有关详细的API，请参阅documentation。
