Connecting to Presto with Python
CData Python Connectors leverage the Database API (DB-API) interface to make it easy to work with Presto 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 Presto
- Query Presto to retrieve or update data
- Connect your Presto data with Python data tools.
Connecting to Presto 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.presto as mod
conn = mod.connect("[email protected]; Password=password;")
#Create cursor and iterate over results
cur = conn.cursor()
cur.execute("SELECT * FROM Tables")
rs = cur.fetchall()
for row in rs:
print(row)
engine = create_engine("presto///Password=password&User=user")
df = pandas.read_sql("SELECT * FROM Tables", engine)
df.plot()
plt.show()
Visualize Presto Data with pandas
The data-centric interfaces of the Presto 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
Presto 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 Presto Connector as easily as interacting with a database table.
AI-assisted development with CData CLI
Build Presto integrations faster with AI that understands your schema
Schema-aware AI
CData CLI gives AI coding tools access to your Presto 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 Presto.
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.
