Loading Metadata into a NoSQL Virtual Data Source¶
Alation does not extract metadata into virtual data sources (VDS). You will need to upload the metadata using the dedicated API.
To upload the metadata,
Click the General Settings tab of your NoSQL VDS setting page to open it:
Under Bulk Upload API, take note of the URL to use in the API calls. It already includes the ID of the current VDS.
Using your API software, create a POST request using the Bulk Upload API URL from Alation. If you are loading schemas in JSON, use the URL as is. If you are loading schemas in the Avro format, you need to append the parameter
?json_type=avroto the URL. For example:
https://test-master.alation-test.com/integration/v1/data/1441/parse_docstore/?json_type=avro. Support of Avro schemas is available starting with release V R6 (5.10.x).
To create the JSON body for your API request refer to NOSQL API documentation.
After the upload, your VDS in Alation will show the metadata you have pushed using the API, with each data object having a dedicated catalog page.
