a remote procedure call software framework for the development of extensible and cross-language services.<br> It combines a powerful software stack and code generation engine,<br> In order to build seamlessly integrated and efficient services among programming languages ​​such as C++, Java, Go, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml.</p><p>IoTDB server and client use thrift for communication. In actual use, it is recommended to use the native client package provided by IoTDB:<br> Session or Session Pool. If you have special needs, you can also program directly against the RPC interface</p><p>The default IoTDB server uses port 6667 as the RPC communication port, you can modify the configuration item</p><div class="language-text line-numbers-mode" data-ext="text" data-title="text"><pre class="language-text"><code>rpc_port=6667
