Introduction</h3> <p>This is an example of how to connect to IoTDB with python, using the thrift rpc interfaces. Things will be a bit different |
| on Linux or Windows, we will introduce how to operate on the two systems separately.</p> <h3 id="_2-prerequisites"><a href="#_2-prerequisites" class="header-anchor">#</a> 2. Prerequisites</h3> <p>python3.7 or later is preferred.</p> <p>You have to install Thrift (0.11.0 or later) to compile our thrift file into python code. Below is the official |
| tutorial of installation:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>http://thrift.apache.org/docs/install/ |
| </code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><h3 id="_3-how-to-get-the-python-library"><a href="#_3-how-to-get-the-python-library" class="header-anchor">#</a> 3. How to Get the Python Library</h3> <h4 id="option-1-pip-install"><a href="#option-1-pip-install" class="header-anchor">#</a> Option 1: pip install</h4> <p>You can find the Apache IoTDB Python Client API package on https://pypi.org/project/apache-iotdb/.</p> <p>The download command is:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>pip install apache-iotdb |
| </code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><h4 id="option-2-use-the-compile-script-we-provided"><a href="#option-2-use-the-compile-script-we-provided" class="header-anchor">#</a> Option 2: use the compile script we provided</h4> <p>If you have added Thrift executable into your path, you may just run <code>client-py/compile.sh</code> or |
| <code>client-py\compile.bat</code>, or you will have to modify it to set variable <code>THRIFT_EXE</code> to point to |
| your executable. This will generate thrift sources under folder <code>target</code>, you can add it to your |
| <code>PYTHONPATH</code> so that you would be able to use the library in your code. Notice that the scripts |
| locate the thrift source file by relative path, so if you move the scripts else where, they are |
| no longer valid.</p> <h4 id="option-3-basic-usage-of-thrift"><a href="#option-3-basic-usage-of-thrift" class="header-anchor">#</a> Option 3: basic usage of thrift</h4> <p>Optionally, if you know the basic usage of thrift, you can only download the thrift source file in |
| <code>service-rpc\src\main\thrift\rpc.thrift</code>, and simply use <code>thrift -gen py -out ./target/iotdb rpc.thrift</code> |
| to generate the python library.</p> <h3 id="_4-use-example"><a href="#_4-use-example" class="header-anchor">#</a> 4. Use Example</h3> <p>We provided an example of how to use the thrift library to connect to IoTDB in <code>client-py/src /client_example.py</code>, please read it carefully before you write your own code.</p></div> <div class="page-nav"><p class="inner"><span class="prev"> |
