ow many virtual nodes should one server have? 🤯

Save this 📌

🧒 Step 1: Think Like This (Simple)
Imagine delivery boys again 🚴
If each handles:
Only 1 area → imbalance ❌
Too many tiny areas → confusion 😵

👉 So what’s the right number?

💡 Reality
👉 There is NO fixed number

It depends on:
Number of servers
Data distribution
Traffic pattern

⚙️ How systems decide?
They aim for:
👉 Balanced load across all servers

🧠 Simple Rule of Thumb
More virtual nodes → better balance
But too many → overhead

👉 So we choose a sweet spot

⚙️ Real World Practice
Typically: 100–200 virtual nodes per server
But depends on system scale

🧠 Real Insight
System design is NOT about exact numbers

👉 It’s about trade-offs

🎯 Interview Insight
If asked this question:
❌ Don’t give fixed number

✅ Say:
“It depends”
Explain trade-off
Mention typical range
