- class langchain_community.storage.redis.RedisStore(*, client: Any = None, redis_url: Optional[str] = None, client_kwargs: Optional[dict] = None, ttl: Optional[int] = None, namespace: Optional[str] = None)[source]¶
BaseStore implementation using Redis as the underlying store.
Examples
Create a RedisStore instance and perform operations on it:
# Instantiate the RedisStore with a Redis connection from langchain_community.storage import RedisStore from langchain_community.utilities.redis import get_client client = get_client('redis://localhost:6379') redis_store = RedisStore(client) # Set values for keys redis_store.mset([("key1", b"value1"), ("key2", b"value2")]) # Get values for keys values = redis_store.mget(["key1", "key2"]) # [b"value1", b"value2"] # Delete keys redis_store.mdelete(["key1"]) # Iterate over keys for key in redis_store.yield_keys(): print(key)
Initialize the RedisStore with a Redis connection.
Must provide either a Redis client or a redis_url with optional client_kwargs.
- Parameters
client – A Redis connection instance
redis_url – redis url
client_kwargs – Keyword arguments to pass to the Redis client
ttl – time to expire keys in seconds if provided, if None keys will never expire
namespace – if provided, all keys will be prefixed with this namespace
Methods

(*[, client, redis_url, ...])Initialize the RedisStore with a Redis connection.
mdelete
(keys)Delete the given keys.
mget
(keys)Get the values associated with the given keys.
mset
(key_value_pairs)Set the given key-value pairs.
yield_keys
(*[, prefix])Yield keys in the store.
