drb-impl-swift 1.0.0

DRB Swift implementation

Swift Implementation

This drb-impl-swift module implements Swift protocol access with DRB data model.

Swift Factory and Swift Node

The module implements the factory model defined in DRB in its node resolver. Based on the python entry point mechanism, this module can be dynamically imported into applications.

The entry point group reference is drb.impl.
The implementation name is swift.
The factory class is encoded into drb_impl_swift.swift_node_factory.
The Swift signature id is 86289118-7797-11ec-90d6-0242ac120003

Using this module

The project is present in https://www.pypi.org service. it can be freely loaded into projects with the following command line:

pip install drb-impl-swift

Access Data

DrbSwiftNode manages the swift protocol to access remote data. The construction parameter is an authentication object.

from drb_impl_swift import SwiftService, SwiftAuth

_os_options = {
    'user_domain_name': 'Default',
    'project_domain_name': 'Default',
    'project_name': 'project_name',
    'project_id': 'project_id',
    'tenant_name': 'tenant_name',
    'tenant_id': 'tenant_id',
    'region_name': 'region_name'
}

auth = SwiftAuth(authurl="https://your_auth_url/v3",
                 auth_version=3, tenant_name="tenant_name",
                 user="user",
                 key='password', os_options=_os_options)

node = SwiftService(auth=auth)

When accessing a SwiftService the node gives access to all the container of this service by giving a list of ContainerNode, and then each container gives a list of ObjectNode for each object in the container.

Limitations

This implementation doesn't allow to write, modify, delete file on a swift container, or it doesn't allow to delete or upload a file. This implementation doesn't allow to download directly an all container.
