-- VEGA Catalog 表结构定义
-- ==========================================

-- ==========================================
-- Schema定义说明（f_schema_definition字段JSON格式）
-- ==========================================
-- f_schema_definition 字段使用JSON数组格式存储所有字段信息，每个字段包含以下属性：
--
-- 基础属性：
--   - name: 字段名称
--   - type: VEGA统一类型 (integer, unsigned_integer, float, decimal, string, text, date, datetime, time, boolean, binary, json, vector)
--   - description: 字段描述
--   - type_config: 类型配置对象 (如 {"max_length": 128}, {"dimension": 768})
--
-- 源端映射：
--   - source_name: 源端字段名（可能与name不同）
--   - source_type: 源端字段类型
--   - is_native: 是否为系统自动同步的字段
--
-- 字段属性：
--   - is_primary: 是否为主键
--   - is_nullable: 是否可为空
--   - default_value: 默认值
--   - ordinal_position: 字段顺序位置
--
-- 字段特征（features数组，可选，用于扩展字段能力）：
--   - feature_type: 特征类型 (keyword, fulltext, vector)
--   - feature_config: 特征配置对象 (如分词器、向量空间类型等)
--   - ref_field_name: 引用的字段名称（用于借用其他字段的能力）
--   - enabled: 是否启用
--
