dagster_gcp.gcs_file_manager ResourceDefinition[source]

FileManager that provides abstract access to GCS.

Implements the FileManager API.

dagster_gcp.gcs.gcs_pickle_io_manager IOManagerDefinition[source]

Persistent IO manager using GCS for storage.

Serializes objects via pickling. Suitable for objects storage for distributed executors, so long as each execution node has network connectivity and credentials for GCS and the backing bucket.

Attach this resource definition to your job to make it available to your ops.

@job(resource_defs={'io_manager': gcs_pickle_io_manager, 'gcs': gcs_resource, ...})
def my_job():
    my_op()

You may configure this storage as follows:

resources:
    io_manager:
        config:
            gcs_bucket: my-cool-bucket
            gcs_prefix: good/prefix-for-files-
