When One Process Isn't Enough

As your bot grows from 100 servers to 10,000, you hit a hard limit: the Discord Gateway connection. A single WebSocket connection can only handle so much traffic before it lags or disconnects. This is where Sharding comes in.

What is Sharding?

Think of Sharding like opening multiple checkout lanes at a grocery store. Instead of one bot process trying to handle every message, you split the load.

• Shard 0: Handles servers 0-999.
• Shard 1: Handles servers 1000-1999.
• And so on.

SkynetBot's Architecture

SkynetBot is built to scale. We use a Process Manager (PM) to spawn shards automatically based on server count.

• Inter-Process Communication (IPC): Shards need to talk to each other. If User A is on Shard 0 and User B is on Shard 1, how do they trade currency? We use a custom Redis-backed IPC layer to sync data instantly.
• State Management: We avoid storing state in memory (RAM) because if a shard crashes, that data is lost. Instead, we use Redis for hot data (caches) and MariaDB/MongoDB for persistent data.

Tips for aspiring Bot Devs

1. Don't block the Event Loop: Node.js is single-threaded. Use async/await properly.
2. Cache aggressively: Don't hit the database for every message.
3. Use a Task Queue: For heavy operations (like image generation), offload them to a worker thread.
