变长字符串，最大支持2147483643 字节（2GB-4）。String类型的长度还受 be 配置 `string_type_soft_limit`, 实际能存储的最大长度 取两者最小值，String类型只能用在value 列，不能用在 key 列和分区 分桶列
变长字符串，最大（默认）支持1048576 字节（1MB）。String类型的长度还受 be 配置 `string_type_length_soft_limit_bytes`, 实际能存储的最大长度 取两者最小值，String类型只能用在value 列，不能用在 key 列和分区 分桶列
注意：变长字符串是以UTF-8编码存储的，因此通常英文字符占1个字节，中文字符占3个字节。
