Valkey GLIDE for Ruby

Valkey General Language Independent Driver for the Enterprise (GLIDE) is the official open-source Valkey client library, part of the Valkey organization. The Ruby gem (valkey-glide-rb) wraps Valkey GLIDE Core, giving Ruby applications the performance and reliability of the GLIDE core.

Features

• Community and Open Source: Developed in the open under the Valkey organization; contributions welcome.
• Reliability: Built with best practices learned from over a decade of operating Redis OSS-compatible services.
• Performance: Optimized for high performance and low latency via the Rust-based GLIDE core.
• High Availability: Cluster-aware routing, reconnection, and fault tolerance.
• Cross-Language Consistency: Same core driver as Python, Java, Node.js, and Go clients.
• Observability: Native OpenTelemetry tracing and client statistics.

Supported Engine Versions

Engine Type	6.2	7.0	7.1	7.2	8.0	8.1	9.0
Valkey	-	-	-	✓	✓	✓	✓
Redis OSS	✓	✓	✓	✓	-	-	-

Getting Started

System Requirements

• glibc 2.17+ or musl 1.2.3+
• Ruby 3.0+

Supported OS

The following platforms are tested in CI:

• Ubuntu 24 (x86_64 and arm64)
• Alpine Linux 3 (x86_64 and arm64, via musl targets)
• macOS 14+ (Apple silicon / arm64)

Notes: valkey-glide-rb depends on the compiled Rust core. For unsupported OS like Intel Mac, you will need to build Valkey GLIDE manually.

Installation and Setup

Install from RubyGems:

gem install valkey-glide-rb

Or add to your Gemfile:

gem "valkey-glide-rb"

Verify installation:

ruby -e 'require "valkey"; puts Valkey::VERSION'

Basic Examples

Standalone Mode

require "valkey"

client = Valkey.new(host: "localhost", port: 6379)

client.set("mykey", "hello world")
# => "OK"

client.get("mykey")
# => "hello world"

client.close

Cluster Mode

nodes = [
  { host: "127.0.0.1", port: 7000 },
  { host: "127.0.0.1", port: 7001 },
  { host: "127.0.0.1", port: 7002 },
  { host: "127.0.0.1", port: 7003 },
  { host: "127.0.0.1", port: 7004 },
  { host: "127.0.0.1", port: 7005 }
]

client = Valkey.new(nodes: nodes, cluster_mode: true)
client.set("foo", "bar")
client.get("foo")
# => "bar"

nodes	Array of { host:, port: } hashes
protocol	:resp2 (default) or :resp3
client_name	CLIENT SETNAME value
reconnect_attempts, reconnect_delay, reconnect_delay_max	Connection retry strategy
read_from	Read routing: the Valkey::ReadFrom::* constants: PRIMARY, PREFER_REPLICA, AZ_AFFINITY, AZ_AFFINITY_REPLICAS_AND_PRIMARY.AZ_AFFINITY/AZ_AFFINITY_REPLICAS_AND_PRIMARY require client_az to also be set.
client_az	Availability-zone identifier for AZ_AFFINITY / AZ_AFFINITY_REPLICAS_AND_PRIMARY routing (e.g. "us-west-2a")
inflight_requests_limit	Maximum concurrent in-flight requests (non-negative integer)
lazy_connect	Delay the actual connection until the first command is sent
periodic_checks	Cluster topology health checks: { manual_interval: { duration_in_sec: N } } or { disabled: true }. Accepted (as a no-op) on standalone connections.
