2. LangGraph Design Patterns

Parallel Execution in LangGraph

Code Example

    futures = [multiply_by_two(number) , multiply_by_three(number)]

    results = [future.result() for future in futures]  

Understanding Execution Patterns

Direct .result() Approach:

• Pehle ek function call hoga aur uska result aane tak wait karega.
• Jab pehla complete ho jaye, tabhi doosra function chalega.
• Matlab step-by-step chalega, ek ke baad doosra (synchronous execution).

Future List Approach:

• Dono functions ek saath call ho jate hain, magar abhi result nahi liya jata.
• Jab result chahiye hoga, toh dono ka result ek saath future se le lenge.
• Parallel execution hoti hai, jo tez hoti hai (asynchronous execution).

Summary

Yani pehle future list mein store karne se dono functions ik saath call hote hain, aur jab result chahiye hota hai, tabhi hum wait karte hain. 🔄🚀
