Connecting to Cassandra with Python
CData Python Connectors leverage the Database API (DB-API) interface to make it easy to work with Cassandra from a wide range of standard Python data tools. Connecting to and working with your data in Python follows a basic pattern, regardless of data source:
- Configure the connection properties to Cassandra
- Query Cassandra to retrieve or update data
- Connect your Cassandra data with Python data tools.
Connecting to Cassandra in Python
To connect to your data from Python, import the extension and create a connection:
Once you import the extension, you can work with all of your enterprise data using the python modules and toolkits that you already know and love, quickly building apps that help you drive business.
import cdata.cassandra as mod
conn = mod.connect("[email protected]; Password=password;")
#Create cursor and iterate over results
cur = conn.cursor()
cur.execute("SELECT * FROM CQL Queries")
rs = cur.fetchall()
for row in rs:
print(row)
engine = create_engine("cassandra///Password=password&User=user")
df = pandas.read_sql("SELECT * FROM CQL Queries", engine)
df.plot()
plt.show()
Visualize Cassandra Data with pandas
The data-centric interfaces of the Cassandra Python Connector make it easy to integrate with popular tools like pandas and SQLAlchemy to visualize data in real-time.
More than read-only: full update/CRUD support
Cassandra Connector goes beyond read-only functionality to deliver full support for Create, Read Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Cassandra Connector as easily as interacting with a database table.
AI-assisted development with CData CLI
Build Cassandra integrations faster with AI that understands your schema
Schema-aware AI
CData CLI gives AI coding tools access to your Cassandra schema. No more guessing table names or column types—AI sees the same metadata in your Python Connectors.
Your AI Knows SQL
How to find table names, column names, and how to generate SQL syntax are things that AI knows well from millions of training data. No need for customization, no hallucinations. Your AI acts like a domain specialist to Cassandra.
More Accurate, More Token-Efficient
With CData CLI's queryable schema detection and highly efficient queries with filters, aggregation, joins with correct pushdown, your AI will achieve more accuracy with less token usage.
