Summary

Melvin Vivas shows that Apache Camel has a topology command that shows how the parts of an integration workflow connect. His example is an OCR pipeline: it reads receipt images from a folder, sends them to an LLM for OCR and JSON extraction, and saves the results to a database. He says this view would be more useful built into Kaoto, Camel's visual designer, especially for large workflows.

Key points

• Apache Camel has a topology command that visualizes how routes, processors, endpoints and services connect.
• Example pipeline: watch a folder of receipt images, send each image to an LLM for OCR and structured JSON extraction, then save the result to a database.
• Apache Camel can act as the orchestration layer for enterprise AI pipelines that combine file input, LLM calls and database output.
• Seeing the topology matters more as workflows grow, because it lets you understand the flow at a glance.
• Kaoto, the visual designer for Camel, does not show this topology view yet. The creator would like it added there.
