## About
[Apache Cassandra][cassandra-docs] is a NoSQL distributed database. By design, NoSQL databases are lightweight, open-source, non-relational, and largely distributed. Counted among their strengths are horizontal scalability, distributed architectures, and a flexible approach to schema definition.
[cassandra-docs]: https://cassandra.apache.org/
## Available Tools
- [`cassandra-cql`](../tools/cassandra/cassandra-cql.md)
Run parameterized CQL queries in Cassandra.
## Example
```yaml
sources:
my-cassandra-source:
kind: cassandra
hosts:
- 127.0.0.1
keyspace: my_keyspace
protoVersion: 4
username: ${USER_NAME}
password: ${PASSWORD}
caPath: /path/to/ca.crt # Optional: path to CA certificate
certPath: /path/to/client.crt # Optional: path to client certificate
keyPath: /path/to/client.key # Optional: path to client key
enableHostVerification: true # Optional: enable host verification
```
{{< notice tip >}}
Use environment variable replacement with the format ${ENV_NAME}
instead of hardcoding your secrets into the configuration file.
