Description

我在数据库存了9780多条时间序列,IOTDB 启动的时候报这个错误(如题),后面我该了 max_deduplicated_path_num in iotdb-engine.properties,错误依旧,我的时间序列命名大概是:
root.00FS030001-861854040011932.signalNoiseRatio.value
其中 00FS030001-861854040011932 是一个设备编号
signalNoiseRatio是这个设备的一个监测项目
我使用的是IOTDB 0,12.1 ,操作系统是centos 8 ,配置8C/32G,目前剩余内存7G
请问如何解决

Research direction

Start by reviewing the startup error and the max_deduplicated_path_num setting in iotdb-engine.properties for IoTDB 0.12.1, using the reported 9,780-plus time series as the reproduction case. Determine why changing the setting has no effect and document a verified resolution for startup with this schema.
