Redis Perf

This is a Go-based project designed to evaluate the performance, consistency, and memory management of Redis. It supports three main scenarios:

1. High-throughput data processing
2. Consistency and failover testing
3. TTL expiration and memory management

Features

1. High-Throughput Data Processing

• Description: Measures Redis throughput by processing large volumes of SET and GET requests.
• Usage: Runs bulk requests to analyze transactions per second (TPS) and response latency.

2. Consistency & Failover Testing

• Description: Tests Redis data consistency during simulated failover events.
• Usage: Simulates master node failure, verifies if data is correctly available after failover.

3. TTL Expiration & Memory Management

• Description: Evaluates Redis key expiration and memory management, verifying EXPIRE behavior and maxmemory-policy.
• Usage: Assigns different TTL values to keys and checks for correct data expiry.

Installation

Clone the repository and build the project:

git clone https://github.com/esperar/redis-perf.git
cd redis-perf
make

Here’s the Redis cluster setup guide in English, formatted using Markdown:

Redis Cluster Setup Guide

This guide explains how to set up a Redis cluster using Docker Compose. The cluster consists of 1 master node and 2 replica nodes.

1. Run Docker Compose

Navigate to the directory where the docker-compose.yml file is located in your terminal, and run the following command to start the Redis cluster:

docker-compose up -d

2. Check Cluster Status

To check the status of the Redis cluster, run the following command:

docker exec -it <master_container_id> redis-cli -p 6379 cluster info

Replace <master_container_id> with the actual container ID of the master node.

3. Check Nodes

To view information about all nodes, use the following command:

docker exec -it <master_container_id> redis-cli -p 6379 cluster nodes

4. Stop the Cluster

To stop the cluster, run the following command:

docker-compose down

This guide will help you easily set up and manage a Redis cluster.

Configuration

Set up Redis and configure as needed in config.yaml:

redis:
  address: "localhost:6379"
  password: ""         # Redis password if set
  db: 0                # Database index
  maxMemoryPolicy: "allkeys-lru"  # Redis eviction policy for TTL tests
test:
  throughputRequests: 10000       # Number of requests for throughput test
  ttlExpiration: [5, 10, 20]      # TTL values in seconds for keys
  failoverSimulation: true        # Enable failover testing

Usage

Each test can be executed independently by using Restful API

GET /failover
GET /throughput
GET /ttl

Example Output

Throughput Test:
    Transactions/sec: 35,000
    Average latency: 1.2ms

Failover Test:
    Failover triggered. Data consistency verified.

TTL Expiration Test:
    Key TTLs expired correctly. Maxmemory-policy enforced.

Requirements

• Redis server (locally or remotely accessible)
• Go 1.18 or later
