SQL 强大的表达能力带来的高可扩展性、灵活性，基本上 Flink SQL 支持的语意，InLong Sort 都支持。 |
| 当 Flink SQL 内置的函数不满足需求时，还可通过 UDF 来扩展。这对于曾经使用过 SQL 尤其是 Flink SQL 的开发者非常友好。</p><p>本文介绍如何在 InLong Sort 中扩展一个新的 source（在 InLong 中抽象为 Extract Node）或一个新的 sink（在InLong中抽象为 Load Node ）。 |
| InLong Sort 架构的 UML 对象关系图如下：</p><p><img loading="lazy" alt="sort_uml" src="/zh-CN/assets/images/sort_uml-d90bb6f0835781e064b7417f266b7b30.png" width="2576" height="869" class="img_ev3q"></p><p>其中各个组件的概念为：</p><table><thead><tr><th><strong>名称</strong></th><th><strong>描述</strong></th></tr></thead><tbody><tr><td>Group</td><td>数据流组，包含多个数据流，一个 Group 代表一个数据接入</td></tr><tr><td>Stream</td><td>数据流，一个数据流有具体的流向</td></tr><tr><td>GroupInfo</td><td>Sort 中对数据流向的封装，一个 GroupInfo 可包含多个 DataFlowInfo</td></tr><tr><td>StreamInfo</td><td>Sort 中数据流向的抽象，包含该数据流的各种来源、转换、去向等</td></tr><tr><td>Node</td><td>数据同步中数据源、数据转换、数据去向的抽象</td></tr><tr><td>ExtractNode</td><td>数据同步的来源端抽象</td></tr><tr><td>TransformNode</td><td>数据同步的转换过程抽象</td></tr><tr><td>LoadNode</td><td>数据同步的去向端抽象</td></tr><tr><td>NodeRelationShip</td><td>数据同步中各个节点关系抽象</td></tr><tr><td>FieldRelationShip</td><td>数据同步中上下游节点字段间关系的抽象</td></tr><tr><td>FieldInfo</td><td>节点字段</td></tr><tr><td>MetaFieldInfo</td><td>节点 Meta 字段</td></tr><tr><td>Function</td><td>转换函数的抽象</td></tr><tr><td>FunctionParam</td><td>函数的入参抽象</td></tr><tr><td>ConstantParam</td><td>常量参数</td></tr></tbody></table><p>扩展 Extract Node 或 Load Node 需要做的工作是：</p><ul><li>继承 Node 类（例如 MyExtractNode），构建具体的 extract 或 load 使用逻辑；</li><li>在具体的 Node 类（例如 MyExtractNode）中，指定对应 Flink connector；</li><li>在具体的 ETL 实现逻辑中使用具体的 Node 类（例如 MyExtractNode）。</li></ul><p>其中第二步中可以使用已有的 Flink Connector，或者用户自己扩展，如何扩展 Flink Connector 请参考 Flink 官方文档<a
