Redis & Oskolok
Oskolok
Hey Redis, what if we built a live art installation where every key change in your store sparks a light or sound effect? Your precision could drive my chaos—imagine a living, responsive masterpiece.
Redis
Sounds like a neat experiment, but before we start painting the room, let’s nail down the schema. Every key change will hit the network, so we’ll need a lightweight event bus, a way to throttle bursts, and a consistent mapping from keys to lights or sounds. Don’t expect me to drop shortcuts – the data path has to stay pure. If you can give me a clear set of events, I’ll make sure the system stays precise, even if the art gets a little chaotic.
Oskolok
Alright, here’s the event playbook, clean and tight:
1. **key.add** – fired when a new key lands in Redis
2. **key.update** – every SET or HSET that changes an existing value
3. **key.delete** – when DEL or UNLINK removes a key
4. **key.expire** – when a key’s TTL reaches zero (automatic expiry)
5. **key.ttl** – periodic ping of a key’s remaining life, for pulse‑driven visuals
Each event carries:
- **key**: the exact key string
- **type**: data type (string, hash, set, etc.)
- **value**: the new or old value (whichever makes sense)
- **timestamp**: ms epoch
**Mapping to lights/sounds**
- Strings → RGB LED colors, brighter with larger values
- Hashes → Multi‑tone chords, fields become notes
- Sets → Perforated drum patterns, each member a hit
- Expiry → Fade‑out effect or sudden silence
**Throttle strategy**
- Window: 100 ms burst window
- Bucket: max 20 events per window, drop excess and log
- If dropped, fire a **key.throttle** event with count, so the artist knows the system’s caught a wave
That’s the skeleton. The data stays pure, the bus stays light, and your art can still go wild. Ready to paint?
Redis
Looks solid, and the mapping is clear enough to keep the lights in sync. Just a couple of thoughts: for the throttle bucket, if you’re going to drop events, make sure the drop‑log is searchable—sudden spikes in traffic can reveal hidden bottlenecks. Also, for key.ttl you’ll want to consider the precision of the periodic ping; if it’s too frequent, you’ll flood the bus, if too sparse, the visual pulse will lag. Other than that, I’ll set up the pub/sub hooks to fire exactly on those events and keep the data path clean. Ready when you are to start the show.

Got it—drop‑logs searchable, ttl ping balanced. I’ll start the code in my studio and keep the fire hot. Just give me a nod and we’ll light up the room.
Redis
Here’s the nod—let’s light it up.
Oskolok
All right, hit the switch—let the colors scream and the beats bleed into the walls. Let’s make the room pulse like a living heart.
Redis
All right, the bus is listening. As soon as a key lands or leaves, the lights will flicker, the sounds will shift, and the room will pulse. Keep an eye on the throttle logs—if anything spikes, we’ll flag it. Let the art begin.
Oskolok
Boom—lights up, beats drop, walls are now a living canvas. Keep an eye on those spikes, and if the art starts to choke, just hit the reset switch. Let’s see what chaos we can paint.
Redis
Sounds great, just watch the logs for spikes and if anything swamps the system hit that reset switch. Let's see how much chaos we can keep under control.
