Exports a copy of all or a subset of documents from Google Cloud Firestore to another storage system, such as Google Cloud Storage. Recent updates to documents may not be reflected in the export. The export occurs in the background and its progress can be monitored and managed via the Operation resource that is created. The output of an export may only be used once the associated operation is done. If an export operation is cancelled before completion it may leave partial data behind in Google Cloud Storage.
This method waits—the workflow execution is paused—until the operation is
complete, fails, or times out. The default timeout value is 1800
seconds (30
minutes) and can be changed to a maximum value of 31536000
seconds (one year)
for long-running operations using the connector_params
field. See the
Connectors reference.
The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.
The polling policy for the long-running operation can be configured. To set the
connector-specific parameters (connector_params
), refer to
Invoke a connector call.
