+## VARIANT
+
+### Description
+
+VARIANT类型
+在 Doris 2.1 中引入一种新的数据类型 VARIANT，它可以存储半结构化 JSON
数据。它允许存储包含不同数据类型（如整数、字符串、布尔值等）的复杂数据结构，而无需在表结构中提前定义具体的列。VARIANT
类型特别适用于处理复杂的嵌套结构，而这些结构可能随时会发生变化。在写入过程中，该类型可以自动根据列的结构、类型推断列信息，并将其合并到现有表的 Schema
中。通过将 JSON 键及其对应的值存储为列和动态子列。
+
+### Note
+
+相比 JSON 类型有有以下优势:
+
+1. 存储方式不同， JSON 类型是以二进制 JSONB 格式进行存储，整行 JSON 以行存的形式存储到 segment 文件中。而 VARIANT
类型在写入的时候进行类型推断，将写入的 JSON 列存化。比JSON类型有更高的压缩比， 存储空间更好。

+2. 查询方式同步，查询不需要进行解析。VARIANT 充分利用 Doris 中列式存储、向量化引擎、优化器等组件给用户带来极高的查询性能。
