Resilient Java Redis Client

Overview

Resilient Java Redis Client is a robust, high-performance library for interacting with Redis in Java applications. Designed with fault tolerance and resilience in mind, it enhances the standard Redis Lettuce client capabilities with advanced features to handle common Redis-related issues seamlessly, ensuring that your application remains stable even when Redis encounters problems.

Key Features:

• Error Handling
  • Automatically manages Redis server errors, serialization errors, and connection issues.
• @Cacheable and @CachePut Compatibility
  • Ensures that the use of @Cacheable annotations continues to work without breaking functionality, even if Redis is temporarily unavailable or misbehaving.
• Resilience Focus
  • Provides a robust caching mechanism that mitigates risks associated with Redis downtimes or failures, allowing your application to operate smoothly.

Support Java 8 or later

Maven

<dependency>
    <groupId>io.github.blaspat</groupId>
    <artifactId>resilient-redis-lettuce-client</artifactId>
    <version>1.0.2</version>
</dependency>

Configuration

I use original spring.redis properties, but you need to add this additional properties

spring:
    timeout: 100ms
    connect-timeout: 100ms
    redis:
      batch-size: 1000
      master:
        host: localhost
        port: 6379
      replica:
        enabled: true
        host: localhost
        port: 6380

• host: your Redis host
• port: your Redis port
• timeout: maximum time the client will wait for a response from the Redis server after a command is sent
• connect-timeout: timeout for establishing a connection to the Redis server
• redis.batch-size: batch size setting for Redis writer, default 1000
• redis.replica.enabled: set totrue if you want to enable read from replica
