class="header-anchor" href="#_1-basic-overview"><span>1. <strong>Basic Overview</strong></span></a></h2><p>IoT-benchmark is a time-series database benchmarking tool developed in Java for big data environments. It was developed and open-sourced by the School of Software, Tsinghua University. The tool is user-friendly, supports various write and query methods, allows storing test information and results for further queries or analysis, and integrates with Tableau for visualizing test results.</p><p>Figure 1-1 illustrates the test benchmark process and its extended functionalities, all of which can be streamlined by IoT-benchmark. It supports a variety of workloads, including write-only, read-only, and mixed write-and-read operations. Additionally, it offers software and hardware system monitoring, performance metric measurement, automated database initialization, test data analysis, and system parameter optimization.</p><figure><img src="/img/benchmark-English1.png" alt="" tabindex="0" loading="lazy"><figcaption></figcaption></figure><p>Figure 1-1 <em>IoT-benchmark Test Benchmark Process</em></p><p>IoT-benchmark adopts the modular design concept of the YCSB test tool, which separates workload generation, performance measurement, and database interface components. Its modular structure is illustrated in Figure 1-2. Unlike YCSB-based testing tools, IoT-benchmark introduces a system monitoring module that supports the persistence of both test data and system metrics. It also includes load-testing functionalities specifically designed for time-series data scenarios, such as batch writes and multiple out-of-order data insertion modes for IoT environments.</p><figure><img src="/img/benchmark-%20English2.png" alt="" tabindex="0" loading="lazy"><figcaption></figcaption></figure><p>Figure 1-2 <em>IoT-benchmark Modular Design</em></p><p><strong>Supported Databases</strong></p><p>Currently, IoT-benchmark supports the following time series databases, versions and connection methods:</p><table><thead><tr><th style="text-align:left;">Database</th><th style="text-align:left;">Version</th><th style="text-align:left;">Connection mmethod</th></tr></thead><tbody><tr><td style="text-align:left;">IoTDB</td><td style="text-align:left;">v1.x v2.x</td><td style="text-align:left;">JDBC, SessionByTablet, SessionByRecord, SessionByRecords</td></tr><tr><td style="text-align:left;">InfluxDB</td><td style="text-align:left;">v1.x v2.x</td><td style="text-align:left;">SDK</td></tr><tr><td style="text-align:left;">TimescaleDB</td><td style="text-align:left;">--</td><td style="text-align:left;">JDBC</td></tr><tr><td style="text-align:left;">OpenTSDB</td><td style="text-align:left;">--</td><td style="text-align:left;">HTTP Request</td></tr><tr><td style="text-align:left;">QuestDB</td><td style="text-align:left;">v6.0.7</td><td style="text-align:left;">JDBC</td></tr><tr><td style="text-align:left;">TDengine</td><td style="text-align:left;">v2.2.0.2</td><td style="text-align:left;">JDBC</td></tr><tr><td style="text-align:left;">VictoriaMetrics</td><td style="text-align:left;">v1.64.0</td><td style="text-align:left;">HTTP Request</td></tr><tr><td style="text-align:left;">KairosDB</td><td style="text-align:left;">--</td><td style="text-align:left;">HTTP Request</td></tr></tbody></table><h2 id="_2-installation-and-operation" tabindex="-1"><a class="header-anchor" href="#_2-installation-and-operation"><span>2. <strong>Installation and Operation</strong></span></a></h2><h3 id="_2-1-prerequisites" tabindex="-1"><a class="header-anchor" href="#_2-1-prerequisites"><span>2.1 <strong>Prerequisites</strong></span></a></h3><ol><li>Java 8</li><li>Maven 3.6+</li><li>The corresponding appropriate version of the database, such as Apache IoTDB 2.0</li></ol><h3 id="_2-2-how-to-obtain" tabindex="-1"><a class="header-anchor" href="#_2-2-how-to-obtain"><span>2.2 <strong>How to Obtain</strong></span></a></h3><ul><li><p><strong>B<strong><strong>inary package</strong></strong>:</strong> Visit <a href="https://github.com/thulab/iot-benchmark/releases" target="_blank" rel="noopener noreferrer">https://github.com/thulab/iot-benchmark/releases</a> to download the installation package.
