Microsoft Azure Synapse

The Microsoft Azure Synapse connection type enables the Azure Synapse Integrations.

Authenticating to Azure Synapse

There are three ways to connect to Azure Synapse using Airflow.

  1. Use token credentials i.e. add specific credentials (client_id, secret, tenant) and subscription id to the Airflow connection.

  2. Use managed identity by setting managed_identity_client_id, workload_identity_tenant_id (under the hook, it uses DefaultAzureCredential with these arguments)

  3. Fallback on DefaultAzureCredential. This includes a mechanism to try different options to authenticate: Managed System Identity, environment variables, authentication through Azure CLI…

Default Connection IDs

All hooks and operators related to Microsoft Azure Synapse use azure_synapse_default by default.
