星云-轻量化小数仓



API 访问地址:


基础环境:

  1. jdk17
  2. mysql 5.7+
  3. StarRocks 3.0
  4. kubesphere + k8s + harbor
  5. flink17
  6. (可选)Hadoop3

详细说明:

  • 启动类: xingyun-app/cn.cloudcharts.XingyunApplication
  • 应用代码生成工具:xingyun-app/cn.cloudcharts.generator.FastAutoGeneratorTest
  • MySQL DB初始化文件: xingyun-docs/sql

数据源管理:

  • 数据源增加:

    'http://localhost:8088/database/add' \
    -H 'accept:*/*' \
    -H 'Content-Type: application/json' \
    -d '{
    "tenantId": 0,
    "name": "dev-starrocks",
    "groupName": "dev",
    "type": "StarRocks",
    "ip": "192.168.217.232",
    "port": 9030,
    "url": "jdbc:mysql://192.168.217.232:9030?useSSL=false&serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&allowMultiQueries=true",
    "username": "root",
    "password": "",
    "note": "string",
    "flinkConfig": "string",
    "flinkTemplate": "string",
    "dbVersion": "3.0",
    "status": true,
    "healthTime": "2023-05-24T05:44:11.673Z",
    "heartbeatTime": "2023-05-24T05:44:11.673Z",
    "enabled": true,
    "createTime": "2023-05-24T05:44:11.673Z",
    "updateTime": "2023-05-24T05:44:11.673Z",
    "code": "1234565"
    }' 
    
    
  • 执行StarRocks SQL

 'http://localhost:8088/executeSql' \
 -H 'accept: */*' \
 -H 'Content-Type: application/json' \
 -d '{
 "statement": "show catalogs;",
 "databaseId": 1,
 "maxRowNum": 100
}'
  • 备注:statement为SQL语句,多个;分割,目前仅支持透出最后一个查询SQL结果传回。原则上IRS只允许传递查询语句。

1、查看catalogs : show catalogs;

 默认内部OLAP:default_catalog
 开发测试环境的Delta:  delta_test
 预发环境的Delta:  delta_test2

2、查询开发测试环境的Delta:

  • 查询 Delta Lake 集群中的数据库: SHOW DATABASES FROM delta_test
  • 查询 Delta Lake 集群中的STG数据库的表: SHOW tables FROM delta_test.stg
  • 查询某张表的数据 select * from delta_test.stg.xxx
