Converting a Logical Model to a Physical Model

Function

This API is used to convert a logical model to a physical model. Information of the target model is displayed if the conversion is successful.

If attributes of the the target model such as id are null, call the following API for obtaining the operation result to view the error message: GET https://{endpoint}/v1/{project_id}/design/operation-results?operation_type=TRANSFORM_LOGIC_MODEL&operation_id={model_id}. {model_id} is a path parameter of the API.

Notes and constraints:

  1. If target_model_id does not match target_model_name, target_model_id prevails.

  2. If target_model_id does not match dw_type, no model can be found and an error message is displayed.

Calling Method

For details, see Calling APIs.

URI

PUT /v1/{project_id}/design/workspaces/{model_id}/transform

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID. For details about how to obtain the project ID, see Project ID and Account ID.

model_id

Yes

String

ID of the relational model. The value of this parameter is of the string type instead of the long type. The value of model_id can be obtained from the API used to obtain a model.

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

IAM token, which is obtained by calling the IAM API for obtaining a user token (value of X-Subject-Token in the response header).

This field is mandatory for authentication using tokens.

workspace

Yes

String

Workspace ID. For details about how to obtain the workspace ID, see Instance ID and Workspace ID.

X-Project-Id

No

String

Project ID. For details about how to obtain the project ID, see Project ID and Account ID.

This parameter is mandatory for API requests that use AK/SK authentication in multi-project scenarios.

Content-Type

No

String

Default value: application/json;charset=UTF-8

This parameter is optional. If the body is available, this parameter is mandatory. If the body is unavailable, you do not need to set this parameter or verify it.

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

target_model_id

No

String

No

String

Description.

update_exist_tables

No

Boolean

Indicates whether to update an existing table.

ids

No

Array of strings

ID list of logical entities to be materialized. The value is of the String type instead of the Long type.

dw_type

Yes

String

Data connection type, which corresponds to the type of the data warehouse where the table is located. The value can be DLI, DWS, MRS_HIVE, POSTGRESQL, MRS_SPARK, CLICKHOUSE, MYSQL, Oracle, or DORIS.

connection_id

No

String

ID of the data connection to which the converted physical table belongs.

database

No

String

Database to which the converted physical table belongs.

queue

No

String

Queue to which the converted physical table belongs (only for DLI).
