Joint Cache Redis

In your busy server cluster, remote caches like Redis are not fast enough.

You have local caches (maybe Guava) to make hot data faster but less consistent.

Now connect all local caches together so that they can share cache updates!

This project shows you how to do this via Redis pub-sub!

Run the demo

1. Start your Redis at default port 6379
2. Run shell command ./gradlew shadowJar
3. Run shell command java -jar build/libs/joint-cache-redis-1.0-SNAPSHOT-all.jar
4. Things are printed in the shell console
5. Ctrl+C (or Cmd+C) to shut it down

Tips:

• You can use the monitor command in redis-cli to watch what happened to Redis.
• Throttling may be needed in big applications.
• Kafka is better here because messages can be consumed by all subscribers. It requires more work in Redis
