Redis Server Binding v0.1.0

The Redis server binding defines server-level configurations for Redis connections in AsyncAPI. This binding configures how the Redis server handles connections, manages resources, and provides infrastructure-level settings for in-memory data storage and pub/sub messaging.

Overview

Redis server bindings configure the server-side behavior and infrastructure settings for Redis connections. These configurations apply to all Redis connections handled by the server and define server-level policies and capabilities for in-memory data storage and pub/sub messaging.

Server Properties

Property	Type	Required	Description
bindingVersion	string	No	Binding version (defaults to 0.1.0)

Property Details

Binding Version

Specifies the version of the Redis server binding being used.

Default: 0.1.0

Note: This is the only property currently defined in the Redis server binding schema. The binding is designed to be minimal and focused on the core Redis capabilities, with room for future expansion.

Redis Server Concepts

Server Infrastructure

Redis servers provide the infrastructure for in-memory data storage and pub/sub messaging:

• Connection Management: Handling multiple concurrent Redis connections
• Memory Management: Managing in-memory data storage and eviction policies
• Pub/Sub System: Real-time messaging infrastructure
• Persistence: Data persistence and backup capabilities

Server Capabilities

Redis servers typically provide these capabilities:

• Connection Limits: Maximum number of concurrent connections
• Memory Limits: Maximum memory usage and eviction policies
• Pub/Sub Channels: Support for unlimited pub/sub channels
• Data Structures: Support for all Redis data types

Server Configuration

Server-level configurations include:

• Security Settings: Authentication, ACLs, network security
• Performance Tuning: Memory limits, connection timeouts, thread pools
• Monitoring: Connection metrics, memory usage, health checks
• Integration: Integration with other services and protocols
