baseplate.clients.cassandra¶
Cassandra is a database designed for high-availability, high write throughput, and eventual consistency.
Baseplate.py supports both the base Python Cassandra driver and the Cassandra ORM, CQLMapper.
Example¶
To integrate the Cassandra driver with your application, add the appropriate client declaration to your context configuration:
baseplate.configure_context(
app_config,
{
...
"foo": CassandraClient("mykeyspace"),
...
}
)
configure it in your application’s configuration file:
[app:main]
...
# required: a comma-delimited list of hosts to contact to find the ring
foo.contact_points = cassandra-01.local, cassandra-02.local
# optional: the port to connect to on each cassandra server
# (default: 9042)
foo.port = 9999
# optional: the name of a CredentialSecret holding credentials for
# authenticating to cassandra
foo.credential_secret = secret/my_service/cassandra-foo
...
and then use the attached Session-like object in
request:
def my_method(request):
request.foo.execute("SELECT 1;")
