Memory

The Memory module provides an in-RAM version of the DBContextStorage class.

class MemoryContextStorage(path='', rewrite_existing=False, partial_read_config=None)

Bases: DBContextStorage

Implements DBContextStorage storing contexts in memory, without file backend. Does not serialize any data. By default, it sets path to an empty string.

Keeps data in a dictionary and two dictionaries:

• main: {context_id: context_info}

• turns: {context_id: {labels, requests, responses}}

Parameters:

• path (str) – Any string, won’t be used.

• rewrite_existing (bool) – Whether TURNS modified locally should be updated in database or not.

• partial_read_config (Optional[Dict[Literal['labels', 'requests', 'responses'], Union[Literal['__all__'], int, Set[int]]]]) – Dictionary of subscripts for all possible turn items.
