<li><p><code>iotdb-engine.properties</code>：IoTDB引擎层系统配置项的默认配置文件。您可以在文件中配置IoTDB引擎运行时的相关参数。此外，用户可以在文件中配置IoTDB存储时TsFile文件的相关信息，如每次将内存中的数据写入到磁盘前的缓存大小(<code>group_size_in_byte</code>)，内存中每个列打一次包的大小(<code>page_size_in_byte</code>)等。</p></li> <li><p><code>logback.xml</code>: 日志配置文件，比如日志级别等。</p></li> <li><p><code>iotdb-cluster.properties</code>: IoTDB集群所需要的一些配置。</p></li></ul>
