+攒批写入没有引入一种新的导入方式，而是对`INSERT INTO tbl VALUES(...)`、`Stream Load`、`Http
Stream`的扩展。
+
+在 Doris
中，所有的数据写入都是一个独立的导入作业，发起一个新的事务，产生一个新的数据版本。在高频写入的场景下，对transaction和compaction都产生了较大的压力。攒批写通过把多个小的写入合成一个写入作业，减少了transaction和compaction的次数，缓解了系统内部的压力，提高了写入的性能。
+
+## 攒批模式
+
+攒批写入有三种模式，分别是：
+
+* `off_mode`
+
+不开启攒批，保持以上三种导入方式的默认行为。
+
+* `sync_mode`
+
+多个用户导入复用一个内部导入，等内部导入成功或失败后，外部导入才会返回。
Review Comment:
这里的外部导入改成客户端会不会好一点，用户可能不理解外部导入的含义
