Map-Reduce Prompting Patterns: Processing Large Data with AI

Map-Reduce Prompting: Processing Large Data with AI

This article is written in English. Our training modules are available in multiple languages.

What happens when your input is too large for a single context window? Or when you need to process 500 documents with the same prompt? Map-Reduce is the answer — a pattern borrowed from distributed computing that splits work into parallelizable chunks, processes each independently, and merges the results.

The Map-Reduce Pattern

Use Case: Document Summarization

Error Handling in Map-Reduce

Advanced: Cascading Map-Reduce

Test Your Understanding

Next Steps

You now command the full prompt orchestration toolkit: chaining, routing, and Map-Reduce. In the next module, you will learn RAG (Retrieval-Augmented Generation) — the technique that gives AI access to YOUR data by combining retrieval with generation.


Continue to RAG Fundamentals to build AI systems grounded in your own data.
