[FUME TO FHIR] HAPI FHIR Peripheral Setup and Validation Issues Explained
[FUME TO FHIR] 14 HAPI FHIR 周邊設定(安控,攔截器,負載)，HAPI Validate可能的問題(data lost)
Summary
This article discusses challenges encountered when implementing HAPI FHIR as a FHIR server. It focuses on the necessity of 'peripheral cooperation' for commercial use, such as security control (Keycloak) and load balancing, and highlights data loss issues observed in the validation function ($validate) during large-scale data processing.
Details
While HAPI FHIR is an easily deployable open-source FHIR server, its deployment for commercial use requires integration with peripheral systems. The article emphasizes the importance of 'peripheral cooperation,' detailing solutions like using Keycloak for authentication and authorization, or employing Nginx for load balancing/reverse proxy setup. A key technical challenge discussed is the validation process. A significant issue noted is data loss when running the $validate function on large datasets (Bundles exceeding 2000 lines). Furthermore, the article points out a critical discrepancy in Implementation Guide (IG) updates: Japanese healthcare systems are adopting IG versions at an extremely high frequency (monthly), which deviates from international standards and complicates compliance. The author positions the FHIR server as a data repository for FUME's conversion process. The text concludes that stable commercial use necessitates robust peripheral solutions, particularly addressing the validation mechanism and ensuring adherence to evolving standards.
