swh.storage.get_storage(cls: str, **kwargs) → StorageInterface

Get a storage object of class cls with arguments **kwargs. cls must be one of the swh.storage.classes entry-points

Parameters:

• cls (str) –

  storage’s class, can be:

  • local to use a postgresql database

  • cassandra to use a cassandra database

  • remote to connect to a swh-storage server

  • memory for an in-memory storage, useful for fast tests

  • filter, buffer, … to use specific storage “proxies”, see their respective documentations

• args (dict) – dictionary with keys

Returns:

an instance of swh.storage.Storage or compatible class

Raises:

ValueError if passed an unknown storage class. –

swh.storage.get_storage_pipeline(steps: List[Dict[str, Any]], check_config=None) → StorageInterface

Recursively get a storage object that may use other storage objects as backends.

Parameters:

steps (List[dict]) – List of dicts that may be used as kwargs for get_storage.

Returns:

an instance of swh.storage.Storage or compatible class

Raises:

ValueError if passed an unknown storage class. –
