Setup

To create a Redis byte store, you'll need to set up a Redis instance. You can do this locally or via a provider - see our Redis guide for an overview of options.

Installation

The LangChain RedisStore integration lives in the langchain_community package:

%pip install -qU langchain_community redis

Instantiation

Now we can instantiate our byte store:

from langchain_community.storage import RedisStore

kv_store = RedisStore(redis_url="redis://localhost:6379")

Usage

You can set data under keys like this using the mset method:

kv_store.mset(
    [
        ["key1", b"value1"],
        ["key2", b"value2"],
    ]
)

kv_store.mget(
    [
        "key1",
        "key2",
    ]
)

[b'value1', b'value2']

And you can delete data using the mdelete method:

kv_store.mdelete(
    [
        "key1",
        "key2",
    ]
)

kv_store.mget(
    [
        "key1",
        "key2",
    ]
)
