class langchain_community.storage.upstash_redis.UpstashRedisByteStore(*, client: Any = None, url: str | None = None, token: str | None = None, ttl: int | None = None, namespace: str | None = None)[source]#

BaseStore implementation using Upstash Redis as the underlying store to store raw bytes.

Methods

`__init__`(*[, client, url, token, ttl, namespace])
`amdelete`(keys)	Async delete the given keys and their associated values.
`amget`(keys)	Async get the values associated with the given keys.
`amset`(key_value_pairs)	Async set the values for the given keys.
`ayield_keys`(*[, prefix])	Async get an iterator over keys that match the given prefix.
`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.

Parameters:

client (Any)
url (str | None)
token (str | None)
ttl (int | None)
namespace (str | None)

__init__(*, client: Any = None, url: str | None = None, token: str | None = None, ttl: int | None = None, namespace: str | None = None) → None[source]#

Parameters:

client (Any)
url (str | None)
token (str | None)
ttl (int | None)
namespace (str | None)

Return type:

None

async amdelete(keys: Sequence[K]) → None#

Async delete the given keys and their associated values.

Parameters:: keys (Sequence[K]) – A sequence of keys to delete.
Return type:: None

async amget(keys: Sequence[K]) → list[V | None]#

Async get the values associated with the given keys.

Parameters:: keys (Sequence[K]) – A sequence of keys.
Returns:: A sequence of optional values associated with the keys. If a key is not found, the corresponding value will be None.
Return type:: list[V | None]

async amset(key_value_pairs: Sequence[tuple[K, V]]) → None#

Async set the values for the given keys.

Parameters:: key_value_pairs (Sequence[Tuple[K, V]]) – A sequence of key-value pairs.
Return type:: None

async ayield_keys(*, prefix: str | None = None) → AsyncIterator[K] | AsyncIterator[str]#

Async get an iterator over keys that match the given prefix.

Parameters:: prefix (str) – The prefix to match.
Yields:: Iterator[K | str] – An iterator over keys that match the given prefix. This method is allowed to return an iterator over either K or str depending on what makes more sense for the given store.
Return type:: AsyncIterator[K] | AsyncIterator[str]

mdelete(keys: Sequence[str]) → None[source]#

Delete the given keys.

Parameters:: keys (Sequence[str])
Return type:: None

mget(keys: Sequence[str]) → List[bytes | None][source]#

Get the values associated with the given keys.

Parameters:: keys (Sequence[str])
Return type:: List[bytes | None]

mset(key_value_pairs: Sequence[Tuple[str, bytes]]) → None[source]#

Set the given key-value pairs.

Parameters:: key_value_pairs (Sequence[Tuple[str, bytes]])
Return type:: None

yield_keys(*, prefix: str | None = None) → Iterator[str][source]#

Yield keys in the store.

Parameters:: prefix (str | None)
Return type:: Iterator[str]
