它结合了功能强大的软件堆栈和代码生成引擎，
以构建在 C++, Java, Go,Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml 这些编程语言间无缝结合的、高效的服务。</p> <p>IoTDB服务端和客户端之间使用thrift进行通信，实际使用中建议使用IoTDB提供的原生客户端封装:
Session或Session Pool。如有特殊需要，您也可以直接针对RPC接口进行编程</p> <p>默认IoTDB服务端使用6667端口作为RPC通信端口，可修改配置项中的</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>rpc_port=6667
