从PostgreSQL数据库test中获取表entity和relation的数据，导入至嬴图数据库的图集shareholding中：

1. 生成配置文件模板

./ultipa-importer --sample

2. 修改配置文件

# 配置数据源类型
mode: postgreSQL

# 配置数据源信息
sqlDatabase:
  host: "192.168.1.1"
  port: "5432"
  dbname: "test"
  username: "admin"
  password: "abcd1234"

# 配置嬴图服务器
server:
  # 嬴图服务器，集群中的多个节点用英文逗号隔开
  host: "192.168.2.149:60075"
  username: "admin"
  password: "abcd1234"
  # 图集名，默认使用图集default
  graphset: "shareholding"
  # 用于远程通信的ssl证书文件的路径及名称，仅在双方均为ssl模式时有效
  crt: ""

# 配置点数据的字段
nodeConfig:
  - schema: "human"
    sql: "select id, name from entity where type = 1"
    properties:
      - name: id
        type: _id
      - name: name
        type: string
  - schema: "firm"
    sql: "select id, name from entity where type = 3"
    properties:
      - name: id
        type: _id
      - name: name
        type: string

# 配置边数据的字段
edgeConfig:
  - schema: "hold"
    sql: "select from, to, shareInt from relation where type = 'holding'"
    properties:
      - name: from
        type: _from
      - name: to
        type: _to
      - name: shareInt
        type: int32
        new_name: share
        
# 全局设置
settings:
  batchSize: 10000
  importMode: insert
  # 自动创建图集、schema和属性
  yes: true

3. 执行导入

./ultipa-importer --config ./import.sample.postgreSQL.yml
