storage

Storage is an implementation of key-value store.

Storage module provides implementations of various key-value stores that conform to a simple key-value interface.

The primary goal of these storages is to support caching.

Class hierarchy:

BaseStore --> <name>Store  # Examples: MongoDBStore, RedisStore

Classes

storage.astradb.AstraDBBaseStore(*args, **kwargs)	Base class for the DataStax AstraDB data store.
storage.cassandra.CassandraByteStore(table, *)	A ByteStore implementation using Cassandra as the backend.
storage.mongodb.MongoDBByteStore(...[, ...])	BaseStore implementation using MongoDB as the underlying store.
storage.mongodb.MongoDBStore(...[, ...])	BaseStore implementation using MongoDB as the underlying store.
storage.redis.RedisStore(*[, client, ...])	BaseStore implementation using Redis as the underlying store.
storage.sql.LangchainKeyValueStores(**kwargs)	Table used to save values.
storage.sql.SQLStore(*, namespace[, db_url, ...])	BaseStore interface that works on an SQL database.
storage.upstash_redis.UpstashRedisByteStore(*)	BaseStore implementation using Upstash Redis as the underlying store to store raw bytes.

Functions
