## What it is
The official Python client driver for Apache Cassandra (and DataStax Enterprise/Astra), communicating via Cassandra's binary protocol and CQL3. It provides sync/async execution, prepared and batch statements, connection pooling, load balancing, retry policies, and an integrated object mapper (cqlengine).

## Use cases
- connect to cassandra from python
- run cql queries from a python application
- execute async queries against cassandra
- map python classes to cassandra tables
- connect to datastax astra cloud database
- tune load balancing and retry policies for cassandra
- use prepared statements with cassandra in python

## When to choose
- your application is written in Python and talks to Apache Cassandra 2.1+ or DSE 4.7+
- you need async IO, connection pooling, and tunable load-balancing/retry policies
- you want an object mapper (cqlengine) for Cassandra tables
- you connect to DataStax Astra or use DSE features like Graph or GSSAPI auth

## When to avoid
- you use a different database (e.g. MongoDB, PostgreSQL) - use its dedicated driver
- you need a non-Python language - use the Java, C++, C#, or Node.js drivers
- you run on big-endian systems, which are not supported

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, orm, serialization, caching
- domain: databases, developer-tools, backend, big-data
- platform: python, windows, cross-platform
- tags: cassandra, cql, nosql, datastax, asyncio, connection-pooling, object-mapper, linux, macos
