Query OK, 2 row(s) in set (0.005122s)七、测试 TDengine 性能
taosBenchmark 是一个专为测试 TDengine 性能而设计的工具它能够全面评估TDengine 在写入、查询和订阅等方面的功能表现。该工具能够模拟大量设备产生的数据并允许用户灵活控制数据库、超级表、标签列的数量和类型、数据列的数量和类型、子表数量、每张子表的数据量、写入数据的时间间隔、工作线程数量以及是否写入乱序数据等策略。
启动 TDengine 的服务在终端中执行如下命令
taosBenchmark -y系统将自动在数据库 test 下创建一张名为 meters的超级表。这张超级表将包含 10,000 张子表表名从 d0 到 d9999每张表包含 10,000条记录。每条记录包含 ts时间戳、current电流、voltage电压和 phase相位4个字段。时间戳范围从 “2017-07-14 10:40:00 000” 到 “2017-07-14 10:40:09 999”。每张表还带有 location 和 groupId 两个标签其中groupId 设置为 1 到 10而 location 则设置为 California.Campbell、California.Cupertino 等城市信息。
执行该命令后系统将迅速完成 1 亿条记录的写入过程。实际所需时间取决于硬件性能但即便在普通 PC 服务器上这个过程通常也只需要十几秒。
taosBenchmark 提供了丰富的选项允许用户自定义测试参数如表的数目、记录条数等。要查看详细的参数列表请在终端中输入如下命令
taosBenchmark --help执行命令taosBenchmark -y
taosBenchmark -y
