Implement File-Based Version of the Redis Cache Adapter
Description and acceptance criteria:
This PR introduces a file-based cache adapter as an alternative to the
existing Redis-based adapter. It provides the same core functionality
for caching session data and maintaining context across multiple user
interactions but stores data locally in files instead of Redis.
Because the shared Kùzu lock mechanism relies on Redis, it is not
supported in this implementation. If a lock is configured, the adapter
will raise an error to prevent misconfiguration.
You can test this adapter by enabling caching with the following
settings:
caching=True
cache_backend="fs"
When running multiple searches in a session, the system should correctly
maintain conversational context. For example:
- What is XY?
- Are you sure?
- What was my first question?
In this case, the adapter should preserve previous user–Cognee
interactions within the cache file so that follow-up queries remain
context-aware.
