Redis Caching Strategy

My site PlayTeraBox.online resolves Terabox video links. Without caching: 1.8s. With Redis: 0.1s.

Implementation

import redis, json
r = redis.Redis(host='localhost', port=6379)

def get_cached(key, fetch_fn, ttl=3600):
    cached = r.get(key)
    if cached: return json.loads(cached)
    result = fetch_fn()
    r.setex(key, ttl, json.dumps(result))
    return result
