Scylla Driver for Apache Cassandra
Decision gist · record as of 2026-08-14
Yes. Scylla Driver is a stable, actively maintained, permissively licensed client for a production database. It has no known vulnerabilities, supports current Python versions, and offers both simple and advanced query patterns. Install it if you need to connect Python applications to Cassandra or Scylla; the medium install friction is typical for drivers with compiled components and is not a barrier.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running Cassandra or Scylla database instance; does not support big-endian systems.
- Medium install friction due to compiled wheels for multiple platforms and Python versions (3.10–3.13 prebuilt).
- Active maintenance with a recent release 60 days ago and ongoing repository activity; no known vulnerabilities.

What it is and what it does
Scylla Driver is a production-grade Python client for Scylla Open Source and Apache Cassandra that implements the Cassandra binary protocol and CQL v3. It provides both synchronous and asynchronous APIs for executing queries, with built-in connection pooling, automatic node discovery, and configurable load-balancing and retry policies. The package includes an integrated object mapper (cqlengine) for ORM-style database interaction and supports Scylla-specific features like shard awareness and tablet awareness.
The driver targets modern Python versions (3.10–3.13 with wheels, 3.14 support declared) and runs on macOS, Linux, and Windows across multiple architectures. Installation is straightforward via pip, though it requires a compiled extension. It is actively maintained, carries no known security vulnerabilities, and is licensed permissively under Apache 2.0.
Use it for
- Building web applications that query Cassandra or Scylla clusters with synchronous or async request patterns.
- Implementing batch data ingestion pipelines using prepared statements and batch operations.
- Creating ORM-based data models with cqlengine for object-relational mapping to CQL tables.
- Developing microservices that require automatic failover and connection pooling across distributed database nodes.
- Running concurrent database operations with configurable retry and load-balancing policies.
