+# DataX GDBReader
+
+## 1. 快速介绍
+
+GDBReader插件实现读取GDB实例数据的功能，通过`Gremlin Client`连接远程GDB实例，按配置提供的`label`生成查询DSL，遍历点或边数据，包括属性数据，并将数据写入到Record中给到Writer使用。
+
+## 2. 实现原理
+
+GDBReader使用`Gremlin Client`连接GDB实例，按`label`分不同Task取点或边数据。
+单个Task中按`label`遍历点或边的id，再切分范围分多次请求查询点或边和属性数据，最后将点或边数据根据配置转换成指定格式记录发送给下游写插件。
+
+GDBReader按`label`切分多个Task并发，同一个`label`的数据批量异步获取来加快读取速度。如果配置读取的`label`列表为空，任务启动前会从GDB查询所有`label`再切分Task。
+
+## 3. 功能说明
+
+GDB中点和边不同，读取需要区分点和边点配置。
+
