data count: **18999994** total SQL: **select * from root.position where time > 1559179819000 limit 10** 执行上述sql: shell client显示花费时间: **6.171S** ![image](https://user-images.githubusercontent.com/41674301/85938068-3f560600-b93c-11ea-8d32-191462885398.png) IOTDB Metrics Server:**0-7ms??????????** ![image](https://user-images.githubusercontent.com/41674301/85938110-8217de00-b93c-11ea-9b86-6abbabbf30b1.png) 为什么两者差别如此之大? 我还尝试使用jdbc api,时间花费在5s,我以为查询会很强,没想到这么弱,感觉比不上HBase... 这是你们的产品介绍,我不知道是否是我的用法有问题,查询根本做不到毫秒级别,超过300W数据就已经是秒级别了,官网的文档也不详细,基本的性能调优我都没有找到。 ![image](https://user-images.githubusercontent.com/41674301/85938135-cefbb480-b93c-11ea-8b00-8d58f4527686.png) 求解惑,还有尽快完善文档吧,连集群模式都没有,生产谁敢用... ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
