+
+由T1, T2 类型元素组成的KV，不能作为key列使用。目前支持在Duplicate，Unique 模型的表中使用。
+
+T支持的类型有：
+
+```
+BOOLEAN, TINYINT, SMALLINT, INT, BIGINT, LARGEINT, FLOAT, DOUBLE, DECIMAL,
DATE,
+DATEV2, DATETIME, DATETIMEV2, CHAR, VARCHAR, STRING
+```
+
+### example
+
+建表示例如下：
+
+```
+ CREATE TABLE IF NOT EXISTS simple_map (
+ `id` INT(11) NULL COMMENT "",
+ `m` Map<STRING, INT> NULL COMMENT ""
+ ) ENGINE=OLAP
+ DUPLICATE KEY(`k1`)
+ DISTRIBUTED BY HASH(`k1`) BUCKETS 1
+ PROPERTIES (
+ "replication_allocation" = "tag.location.default: 1",
+ "storage_format" = "V2"
+ )
+```
+
+插入数据示例：
+
+```
+mysql> INSERT INTO simple_map VALUES(1, {'a': 100, 'b': 200});
+```
+
+查询数据示例：
+
+```
+mysql> SELECT * FROM simple_map;
++------+-----------------------------+
+| id | m |
++------+-----------------------------+
+| 1 | {'a':100, 'b':200} |
+| 2 | {'b':100, 'c':200, 'd':300} |
+| 3 | {'a':10, 'd':200} |
++------+-----------------------------+
