### 配置和运行方式 ### 配置和运行方式
taosBenchmark 支持两种配置方式：[命令行参数](#命令行参数) 和 [JSON 配置文件](#json-配置文件)。这两种方式是互斥的，在使用配置文件时只能使用一个命令行参数 `-f <json file>` 指定配置文件。在使用命令行参数运行 taosBenchmark 并控制其行为时则不能使用 `-f` 参数而要用其它参数来进行配置。除此之外，taosBenchmark 还提供了一种特殊的运行方式，即无参数运行。 taosBenchmark 支持两种配置方式：[命令行参数](#命令行参数详解) 和 [JSON 配置文件](#配置文件参数详解)。这两种方式是互斥的，在使用配置文件时只能使用一个命令行参数 `-f <json file>` 指定配置文件。在使用命令行参数运行 taosBenchmark 并控制其行为时则不能使用 `-f` 参数而要用其它参数来进行配置。除此之外，taosBenchmark 还提供了一种特殊的运行方式，即无参数运行。
taosBenchmark 支持对 TDengine 做完备的性能测试，其所支持的 TDengine 功能分为三大类：写入、查询和订阅。这三种功能之间是互斥的，每次运行 taosBenchmark 只能选择其中之一。值得注意的是，所要测试的功能类型在使用命令行配置方式时是不可配置的，命令行配置方式只能测试写入性能。若要测试 TDegnine 的查询和订阅性能，必须使用配置文件的方式，通过配置文件中的参数 `filetype` 指定所要测试的功能类型。 taosBenchmark 支持对 TDengine 做完备的性能测试，其所支持的 TDengine 功能分为三大类：写入、查询和订阅。这三种功能之间是互斥的，每次运行 taosBenchmark 只能选择其中之一。值得注意的是，所要测试的功能类型在使用命令行配置方式时是不可配置的，命令行配置方式只能测试写入性能。若要测试 TDegnine 的查询和订阅性能，必须使用配置文件的方式，通过配置文件中的参数 `filetype` 指定所要测试的功能类型。
