langchain_community.storage.astradb.AstraDBByteStore

class langchain_community.storage.astradb.AstraDBByteStore(collection_name: str, token: Optional[str] = None, api_endpoint: Optional[str] = None, astra_db_client: Optional[Any] = None, namespace: Optional[str] = None)

ByteStore implementation using DataStax AstraDB as the underlying store. The bytes values are converted to base64 encoded strings Documents in the AstraDB collection will have the format {

“_id”: “<key>”, “value”: “<byte64 string value>”

}

Methods

__init__(collection_name[, token, ...])
decode_value(value)	Decodes value from Astra DB
encode_value(value)	Encodes value for Astra DB
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.

__init__(collection_name: str, token: Optional[str] = None, api_endpoint: Optional[str] = None, astra_db_client: Optional[Any] = None, namespace: Optional[str] = None) → None

decode_value(value: Any) → Optional[bytes]

Decodes value from Astra DB

encode_value(value: Optional[bytes]) → Any

Encodes value for Astra DB

mdelete(keys: Sequence[str]) → None

Delete the given keys.

mget(keys: Sequence[str]) → List[Optional[V]]

Get the values associated with the given keys.

mset(key_value_pairs: Sequence[Tuple[str, V]]) → None

Set the given key-value pairs.

yield_keys(*, prefix: Optional[str] = None) → Iterator[str]

Yield keys in the store.
