kylin 的官网没有列出保存 cube 信息，model 信息，project等 rest api，这里通过查看源码对实际项目使用中有用到的 api 进行列举
官方文档
http://kylin.apache.org/docs16/howto/howto_use_restapi.html#build-cube
保存项目
POST /kylin/api/projects
ProjectController.java
Request Body
- name -
requiredString项目名 - description -
optionalString项目描述
导入 hive table
POST /kylin/api/tables/{tables}/{project}
Request Parameters
- tables -
requiredstring需要导入的表名，用 , 分隔 - project -
requiredString导入的目标项目
Response Sample
{
"result.loaded": ["DEFAULT.SAMPLE_07"],
"result.unloaded": ["sapmle_08"]
}
保存 model
POST /kylin/api/models
ModelController.java
Request Body
- project -
requiredString项目名 - modelName -
requiredStringModel 名 - modelDescData -
requiredStringmodel 描述字符串，json 中必须用字符串，即 " 用 " 表示，详见下面例子
post json 请求示例
{
"project": "game_inner",
"modelName": "test_model2",
"modelDescData": "{\"name\": \"test_model2\", \"owner\": \"ADMIN\", \"description\": \"\", \"fact_table\": \"KYLIN_FLAT_DB.FACT_GAME\", \"lookups\": [], \"dimensions\": [ { \"table\": \"KYLIN_FLAT_DB.FACT_GAME\", \"columns\": [ \"STARTTIME\", \"USERID\", \"GAME\", \"TYPEID\", \"DURATION\", \"LOCATIONID\" ] } ], \"metrics\": [ \"STARTTIME\", \"USERID\", \"GAME\", \"TYPEID\", \"DURATION\", \"LOCATIONID\" ], \"filter_condition\": \"\", \"partition_desc\": { \"partition_date_column\": null, \"partition_time_column\": null, \"partition_date_start\": 0, \"partition_date_format\": \"yyyy-MM-dd\", \"partition_time_format\": \"HH:mm:ss\", \"partition_type\": \"APPEND\", \"partition_condition_builder\": \"org.apache.kylin.metadata.model.PartitionDesc$DefaultPartitionConditionBuilder\" }, \"capacity\": \"MEDIUM\"}"
