Description

请教一个问题,在用iotdb查询历史值时出现这样一个问题,存在某一个历史时刻(2022-04-22 00:56:44),如果查询的历史段为(2022-04-22 00:00:00 - 2022-04-22 01:00:00)包含这个历史时刻,则只能查找到从开始时间到(2022-04-22 00:56:44)的值,之后的值无法正常显示,这个历史时刻之后经查验是有值存储于iotdb。利用iotdb cli运行sql查询count可以得到该时间段正确的存储数量,但是实际查看数据明细的时候仍然存在断点问题。查询(2022-04-22 00:56:44)前后的数据都是正常显示的,只要包含那个有问题的历史时刻查询的结果就是有问题的。目前是在麒麟的操作系统上部署的0.12.4,不清楚是什么原因导致的。

Research direction

Start by reproducing the issue in the IoTDB 0.12.4 CLI on the reported 麒麟 environment, querying details and count across 2022-04-22 00:56:44. No source file or test is named; compare the detail results before and after that timestamp and document a verified cause and correction or workaround.
