This is only an example DAG to highlight usage of AzureCosmosDocumentSensor to detect |
|
if a document now exists. |
|
|
|
You can trigger this manually with `airflow dags trigger example_cosmosdb_sensor`. |
|
|
|
*Note: Make sure that connection `azure_cosmos_default` is properly set before running |
|
this example.* |
