Export entities from Google Cloud Datastore to Cloud Storage

  • bucket (str) – name of the cloud storage bucket to backup data

  • namespace (str) – optional namespace path in the specified Cloud Storage bucket to backup data. If this namespace does not exist in GCS, it will be created.

  • datastore_conn_id (str) – the name of the Datastore connection id to use

  • cloud_storage_conn_id (str) – the name of the cloud storage connection id to force-write backup

  • delegate_to (str) – The account to impersonate, if any. For this to work, the service account making the request must have domain-wide delegation enabled.

  • entity_filter (dict) – description of what data from the project is included in the export, refer to

  • labels (dict) – client-assigned labels for cloud storage

  • polling_interval_in_seconds (int) – number of seconds to wait before polling for execution status again

  • overwrite_existing (bool) – if the storage bucket + namespace is not empty, it will be emptied prior to exports. This enables overwriting existing backups.

  • xcom_push (bool) – push operation name to xcom for reference
