Cache & Key-Value Workloads

In-memory caching solutions for high-performance applications.

Available Workloads

Valkey

Redis-compatible in-memory data store with phpCacheAdmin web UI.

Features:

• Redis protocol compatible
• High performance (100k+ ops/sec)
• Data persistence options
• Pub/Sub messaging
• Multiple data structures (strings, hashes, lists, sets, sorted sets)

Use Cases:

• Session storage
• Cache layer
• Real-time analytics
• Message broker
• Rate limiting

Deployment:

# Add and deploy
loko workloads add valkey --now

# Get connection details
loko workloads connect valkey

Endpoints:

• Cache Server: Port 6379
• Web UI (phpCacheAdmin/cache-ui): https://cache-ui.${LOKO_DOMAIN}

Connection String:

redis://:${PASSWORD}@valkey.${LOKO_DOMAIN}:6379

Configuration Example:

# Python with redis-py
import redis

r = redis.Redis(
    host='valkey.${LOKO_DOMAIN}',
    port=6379,
    password='<your-password>',
    decode_responses=True
)

r.set('key', 'value')
print(r.get('key'))

Memcached

High-performance distributed memory caching system with phpCacheAdmin web UI.

Features:

• Simple key-value storage
• High performance (50k+ ops/sec)
• Multi-threaded architecture
• LRU eviction policy
• Binary and text protocols

Use Cases:

• Database query caching
• Session storage
• Full page caching
• API response caching
• Object caching

Deployment:

# Add and deploy
loko workloads add memcached --now

# Get connection details
loko workloads connect memcached

Endpoints:

• Cache Server: Port 11211
• Web UI (phpCacheAdmin): https://cache-ui.${LOKO_DOMAIN}

Connection String:

memcached.${LOKO_DOMAIN}:11211

Configuration Example:

# Python with pymemcache
from pymemcache.client import base

client = base.Client(('memcached.${LOKO_DOMAIN}', 11211))
client.set('key', 'value')
print(client.get('key'))

Cache UI

Unified web interface for managing Redis, Memcached, and other cache backends using phpCacheAdmin.

Features:

• Multi-backend support (Redis, Memcached, APCu)
• Real-time statistics and monitoring
• Key/value browsing and editing
• Server switching in single interface
• Redis cluster and ACL support

Access:

https://cache-ui.${LOKO_DOMAIN}

The cache-ui workload automatically connects to both Valkey and Memcached instances when deployed.
