This project implements a reactive architecture for managing loan applications, focusing on the highlighted part:
- Data Upload Service: Responsible for uploading documents to an S3 bucket and sending document IDs to a Kafka topic (
data_upload_topic). - Commercial Service: Consumes document IDs from the Kafka topic, forwards them to the OCR microservice, and calculates an initial score for the application based on data from external databases and OCR results.
- OCR Microservice: Reads document IDs from a Kafka topic (
doc_topic), performs OCR on the corresponding documents, and stores the OCR results in a MongoDB database (ocr_results_db).
Technologies Used:
- Apache Kafka: For asynchronous communication between microservices.
- Amazon S3: For storing uploaded documents.
- MongoDB: For storing OCR results.
- Java: For implementing microservices and interacting with databases.
Note: The actual implementation involves real database connections, AWS S3 usage, and Kafka configurations, while the provided code snippets contain mock logic for demonstration purposes.
