StoreBackend(fixed_length_key=False, suppress_store_backend_id=False, manually_initialize_store_backend_id: str = ‘’, store_name=’no_store_name’)

A store backend acts as a key-value store that can accept tuples as keys, to abstract away

InMemoryStoreBackend(runtime_environment=None, fixed_length_key=False, suppress_store_backend_id=False, manually_initialize_store_backend_id: str = ‘’, store_name=None)

Uses an in-memory dictionary as a store backend.

class great_expectations.data_context.store.store_backend.StoreBackend(fixed_length_key=False, suppress_store_backend_id=False, manually_initialize_store_backend_id: str = '', store_name='no_store_name')

A store backend acts as a key-value store that can accept tuples as keys, to abstract away reading and writing to a persistence layer.

In general a StoreBackend implementation must provide implementations of:
  • _get

  • _set

  • list_keys

  • _has_key

_construct_store_backend_id(self, suppress_warning: bool = False)

Create a store_backend_id if one does not exist, and return it if it exists If a valid UUID store_backend_id is passed in param manually_initialize_store_backend_id and there is not already an existing store_backend_id then the store_backend_id from param manually_initialize_store_backend_id is used to create it. :param suppress_warning: boolean flag for whether warnings are logged

Returns

store_backend_id which is a UUID(version=4)
