# Cassandra Database Plugin
Name: `cassandra-database-plugin`
The Cassandra Database Plugin is one of the supported plugins for the Database
backend. This plugin generates database credentials dynamically based on
configured roles for the Cassandra database.
See the [Database Backend](/docs/secrets/databases/index.html) docs for more
information about setting up the Database Backend.
## Quick Start
After the Database Backend is mounted you can configure a cassandra connection
by specifying this plugin as the `"plugin_name"` argument. Here is an example
cassandra configuration:
```
$ vault write database/config/cassandra \
plugin_name=cassandra-database-plugin \
allowed_roles="readonly" \
hosts=localhost \
username=cassandra \
password=cassandra
The following warnings were returned from the Vault server:
* Read access to this endpoint should be controlled via ACLs as it will return the connection details as is, including passwords, if any.
```
Once the cassandra connection is configured we can add a role:
```
$ vault write database/roles/readonly \
db_name=cassandra \
creation_statements="CREATE USER '{{username}}' WITH PASSWORD '{{password}}' NOSUPERUSER; \
GRANT SELECT ON ALL KEYSPACES TO {{username}};" \
default_ttl="1h" \
max_ttl="24h"
Success! Data written to: database/roles/readonly
```
This role can be used to retrieve a new set of credentials by querying the
"database/creds/readonly" endpoint.
## API
The full list of configurable options can be seen in the [Cassandra database
plugin API](/api/secret/databases/cassandra.html) page.

backend API](/api/secret/databases/index.html) page.
