Aaj ke time me:

✔ Data bahut fast grow ho raha hai
✔ Users bahut zyada queries run kar rahe hain
✔ Reports real-time chahiye

Traditional database model is load ko handle karne me struggle karta hai.

Is problem ka modern solution hai:

👉 MPP – Massively Parallel Processing


Basic Idea – Sequential vs Parallel

Traditional Processing (Sequential)

Agar ek query me 5 tasks hain:

Task 1
Task 2
Task 3
Task 4
Task 5

Traditional system:

Ek ke baad ek execute karega.

Total time = sab tasks ka total time.

Slow.


MPP Processing (Parallel)

MPP system:

Sab tasks ek sath execute karega.

Task 1 → Node 1
Task 2 → Node 2
Task 3 → Node 3
Task 4 → Node 4
Task 5 → Node 5

Total time = slowest single task ka time.

Bahut fast


MPP Architecture Types

MPP ke 2 main architectures hote hain:


1️⃣ Shared Disk Architecture

✔ Compute nodes alag hote hain
✔ Storage central hota hai

Matlab:

Sab nodes ek hi disk se data read karte hain
But processing parallel hoti hai

Benefit:

✔ Faster than traditional
✔ Easier data management

Limitation:

Central disk bottleneck ban sakta hai.


2️⃣ Shared Nothing Architecture (Modern & Powerful)

Ye most advanced model hai.

Isme:

✔ Storage alag
✔ Compute alag
✔ Har node independent

Har node:

  • Apna CPU
  • Apni RAM
  • Apni disk
  • Apna OS

Kuch bhi share nahi karta.

Isliye bolte hain:

👉 Shared Nothing


Why Shared Nothing Is Powerful?

Imagine 3 nodes hain:

Node 1 → Data part 1
Node 2 → Data part 2
Node 3 → Data part 3

Query aayi:

System query ko break karega
Har node apne data par kaam karega
Final result combine hoga

Super scalable 🚀

Agar aur performance chahiye?

👉 Aur nodes add kar do.


Real-World Example

Suppose:

Sales table = 1 billion rows

Traditional system:

Single server → slow

MPP system:

10 nodes
Each process 100 million rows

Result = 10x faster


Kaun Use Karta Hai MPP?

Modern cloud data warehouses use MPP:

  • Snowflake
  • Azure Synapse
  • Amazon Redshift
  • Google BigQuery

Ye sab MPP architecture par based hain.


Simple Formula

Traditional = 1 brain working
MPP = Multiple brains working together

Zyada brains → Faster thinking
