The snowflake endpoint allows you to connect and manage Snowflake data sources in Immuta.
Additional fields may be included in some responses you receive; however, these attributes are for internal purposes and are therefore undocumented.
Snowflake workflow
Snowflake imported databases
Immuta does not support Snowflake tables from imported databases. Instead, create a view of the table and register that view as a data source.
Create a data source
POST /snowflake/handler
Save the provided connection information as a data source.
Payload parameters
Attribute
Description
Required
boolean When false, the data source will be publicly available in the Immuta UI.
array[object] The parameters for this array include scheme ("https") and url (an empty string).
string Describes the type of underlying blob handler that will be used with this data source (e.g., MS SQL).
string The data format of blobs in the data source, such as json, xml, html, or jpeg.
string The type of data source: ingested (metadata will exist in Immuta) or queryable (metadata is dynamically queried).
string The name of the data source. It must be unique within the Immuta tenant.
string A string that represents this data source's table in Immuta.
string The organization that owns the data source.
string The category of the data source.
string The description of the data source.
boolean When true, the data source contains examples.
Response parameters
integer The ID of the data source.
string This message describes issues with the created data source, such as the data source being unhealthy.
string The connection string used to connect the data source to Immuta.
Request example
