# valkey-glide-sync — Valkey GLIDE Sync client. Supports Valkey and Redis OSS.

License: permissive · Maintenance: active · Downloads: 274.5K/mo

## What it is and what it does

Valkey GLIDE Sync is the official synchronous Python client for Valkey and Redis OSS, built on a Rust core with Python-specific bindings. It provides blocking operations for connecting to Valkey servers in either standalone or cluster mode, supporting key-value commands, pub/sub messaging with dynamic subscription management, and automatic failover. The package is maintained by the Valkey organization and backed by AWS and GCP.

The sync variant is designed for applications that prefer or require blocking I/O rather than async patterns. It depends on cffi, protobuf, and typing-extensions. Installation uses precompiled wheels for Python versions 3.10–3.14 on Linux (x86_64, aarch64) and macOS (Intel, Apple Silicon), with medium install friction. The package is actively maintained and carries no known security vulnerabilities.

Use it for:

- Traditional blocking web frameworks needing Redis caching without async refactoring
- Synchronous batch processing or ETL pipelines that read/write to Valkey for state
- Pub/sub message handling in blocking contexts with automatic subscription reconciliation
- Cluster-aware key-value operations across sharded Valkey deployments
- Migration from older Redis clients to an officially maintained alternative

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Synchronous Python client for Valkey and Redis OSS providing blocking operations for key-value storage, pub/sub messaging, and cluster or standalone connectivity.

Yes. Valkey GLIDE Sync is the official, actively maintained synchronous client for Valkey/Redis OSS with no known vulnerabilities, permissive Apache-2.0 licensing, and broad platform support. Choose it if you need blocking I/O, cluster awareness, or official Valkey backing. Medium install friction is acceptable given precompiled wheels and active maintenance.

## Install

pip install valkey-glide-sync
uv add valkey-glide-sync
poetry add valkey-glide-sync

## Installing valkey-glide-sync

Before you install: Medium install friction due to precompiled wheels across Python versions 3.10–3.14 on macOS and Linux (x86_64, aarch64). Active maintenance with a release 4 days old. Requires cffi, typing-extensions, and protobuf as runtime dependencies.

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial use, modification, and distribution with minimal restrictions—suitable for most production and proprietary projects.

Quickstart:

pip install valkey-glide-sync

from glide_sync import GlideClientConfiguration, NodeAddress, GlideClient

config = GlideClientConfiguration(
    addresses=[NodeAddress("localhost", 6379)],
    request_timeout=500
)
client = GlideClient.create(config)
result = client.set("key", "value")
print(client.get("key"))

Requires a running Valkey or Redis OSS server accessible at the configured address and port.

Verify before relying:

- Exact Python version support range (requires_python field is unspecified in metadata)
- Whether Alpine Linux / MUSL support has been added since the documented limitation
- Performance characteristics and latency profile in production deployments
