Redis Cache

Configuration

[cache]
cache_type = "Redis"
redis_url = "redis://localhost:6379"
max_size_mb = 100

What’s cached

• Product catalogue queries
• Category listings
• Session data
• Rate limiter state

Without Redis

Default is in-memory cache (cache_type = "Memory"). Works for single-instance deployments.

Redis setup

# Install Redis
sudo apt install redis-server

# Configure Redis
sudo vim /etc/redis/redis.conf
# Set: requirepass your_password

# Update rCommerce config
[cache]
cache_type = "Redis"
redis_url = "redis://:your_password@localhost:6379"

Multiple instances

With Redis, multiple rCommerce instances can share cache and session data:

Instance 1 → Redis ← Instance 2

Cache invalidation

Cache is automatically invalidated when:

• Products are created/updated/deleted
• Categories change
• Orders are placed
• Configuration changes
