This document summarizes Redis caching and PubSub capabilities. Redis can be used as a cache with two approaches - TTL and volatile objects. Configuration options for caching include maxmemory, maxmemory-policy, and maxmemory-samples. Redis also supports publishing and subscribing to channels. Commands include subscribe, unsubscribe, publish, psubscribe, and punsubscribe. Psubscribe allows glob pattern matching to subscribe to multiple channels. Potential use cases for PubSub include chat applications, notification systems, and message queues.

- 4. Cache Redis • 2 cara : TTL , Volatile Object maxmemory
- 5. Redis as an LRU cache Least Recently Used
- 6. konfigurasi • maxmemory bytes • maxmemory-policy policy • maxmemory-samples jml_sample
- 7. Conf : maxmemory • Bytes 1k => 1000 bytes 1kb => 1024 bytes 1m => 1000000 bytes 1mb => 1024*1024 bytes 1g => 1000000000 bytes 1gb => 1024*1024*1024 bytes
- 8. Conf : maxmemory-policy • volatile-lru (default) • allkeys-lru • volatile-random • allkeys-random • volatile-ttl • noeviction
- 9. Conf : maxmemory-samples • Default : 3 • TTL dan LRU bukan ‘precise algorithms’
- 10. PubSub Redis
- 11. Command • subscribe • unsubscribe • publish • psubscribe • punsubscribe
- 12. PSUBSCRIBE dan PUNSUBSCRIBE • Glob pattern matching • Ex : PSUBSCRIBE news.* match : news.art, news.world.war channel
