RedisConversationMemoryDriver

Bases: BaseConversationMemoryDriver

A Conversation Memory Driver for Redis.

This driver interfaces with a Redis instance and utilizes the Redis hashes and RediSearch module to store, retrieve, and query conversations in a structured manner. Proper setup of the Redis instance and RediSearch is necessary for the driver to function correctly.

Attributes:

Name Type Description
host str

The host of the Redis instance.
port int

The port of the Redis instance.
db int

The database of the Redis instance.
password Optional[str]

The password of the Redis instance.
index str

The name of the index to use.
conversation_id str

The id of the conversation.
