# Cassandra
> [Apache Cassandra®](https://cassandra.apache.org/) is a NoSQL, row-oriented, highly scalable and highly available database.
> Starting with version 5.0, the database ships with [vector search capabilities](https://cassandra.apache.org/doc/trunk/cassandra/vector-search/overview.html).
The integrations outlined in this page can be used with `Cassandra` as well as other CQL-compatible databases,
i.e. those using the `Cassandra Query Language` protocol.
## Installation and Setup
Install the following Python package:
```bash
pip install "cassio>=0.1.6"
```
## Vector Store
```python
from langchain_community.vectorstores import Cassandra
```
Learn more in the [example notebook](/docs/integrations/vectorstores/cassandra).
## Chat message history
```python
from langchain_community.chat_message_histories import CassandraChatMessageHistory
```
Learn more in the [example notebook](/docs/integrations/memory/cassandra_chat_message_history).
## LLM Cache
```python
from langchain.globals import set_llm_cache
from langchain_community.cache import CassandraCache
set_llm_cache(CassandraCache())
```
Learn more in the [example notebook](/docs/integrations/llm_caching#cassandra-caches) (scroll to the Cassandra section).
## Semantic LLM Cache
```python
from langchain.globals import set_llm_cache
from langchain_community.cache import CassandraSemanticCache
set_llm_cache(CassandraSemanticCache(
embedding=my_embedding,
table_name="my_store",
))
```
Learn more in the [example notebook](/docs/integrations/llm_caching#cassandra-caches) (scroll to the appropriate section).
## Document loader
```python
from langchain_community.document_loaders import CassandraLoader
```
Learn more in the [example notebook](/docs/integrations/document_loaders/cassandra).

## Toolkit
The `Cassandra Database toolkit` enables AI engineers to efficiently integrate agents
with Cassandra data.
```python
from langchain_community.agent_toolkits.cassandra_database.toolkit import (
CassandraDatabaseToolkit,
)
```
