FHIR2SQL

A Rust-based application that synchronizes FHIR (Fast Healthcare Interoperability Resources) data with a PostgreSQL database.

Overview

This application connects to a FHIR server, retrieves data, and syncs it with a PostgreSQL database. It uses the sqlx library for database interactions and reqwest for making HTTP requests to the FHIR server. The application is designed to run continuously, syncing data at regular intervals.

Features

• Connects to a PostgreSQL database and creates necessary tables and triggers if they don't exist
• Retrieves FHIR data from a specified server and syncs it with the PostgreSQL database
• Supports regular syncing at a specified interval
• Handles errors and retries connections to the FHIR server and PostgreSQL database
• Supports graceful shutdown on SIGTERM and SIGINT signals

Components

• main.rs: The main application entry point
• db_utils.rs: Database utility functions for connecting to PostgreSQL and creating tables and triggers
• models.rs: Data models for FHIR resources and database interactions
• graceful_shutdown.rs: Functions for handling graceful shutdown on SIGTERM and SIGINT signals

Getting Started

To use this application, you'll need to:

1. Install Rust and the required dependencies
2. Configure the application by setting environment variables for the FHIR server URL, PostgreSQL connection details, and syncing interval
3. Run the application using cargo run
