What this category of data looks like
Data mainly originates from the "One Task" zone of the national government service platform, local integrated government service platforms, electronic certificate databases, and various department approval systems. The update frequency is daily. Daily documents include joint handling item lists, one-time notice sheets, joint handling application forms, material circulation sheets, parallel approval opinions, and completion receipts. Fields cover item numbers, associated departments, material details, processing nodes, completion status, and other items. There is no fixed unified format, and processing requires adaptation to multiple types of document structures.
What constraints do these characteristics impose on the deployment and upgrade link
Since data sources cover multiple platforms and update daily, stability and compliance of multi-source data synchronization must be ensured. Diverse document types and non-unified field standards require adaptation to different document structures for chunking and vector generation. Joint handling data involves cross-department permissions, so storage and access compliance must be strictly controlled. At the same time, daily new original files, chunked data, and embedding vectors will continuously occupy disk space. Storage and cleanup strategies must be properly configured to avoid resource overload that affects normal operation of government services.
How to set the configurations
| Configuration Item | Suggested Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 300–500 connections | Joint handling data connects to multiple department systems, requires support for a relatively large number of cross-table connections to avoid synchronization interruptions caused by exhausted connections |
STORAGE_S3_ENDPOINT | Fill in the address of the local government cloud storage node | Joint handling data is mostly stored on government cloud platforms, adapting to compliance access requirements of official storage |
REDIS_URL | Configure the address of the local government intranet Redis instance | Ensure low latency for joint handling data synchronization and caching, meeting real-time requirements of government services |
FILE_TOKEN_KEY | Use the unified issued secret key from the government platform | Ensure compliance of access permissions for joint handling material files, avoiding unauthorized access |
FE_DOMAIN | Fill in the official domain name of the government service portal | Adapt to cross-domain rules for front-end display, ensuring normal loading of interface resources |
MONGODB_URI | Bind the address of the government-specific MongoDB cluster | Joint handling data updates daily and its total volume gradually grows, requiring stable storage and read/write capabilities |
Three Common Mistakes
- Phenomenon: When adding joint handling attachments after an upgrade, the prompt
fail to create post presigned urlappears. Cause:FILE_TOKEN_KEYhas not been synchronized to the new version-compatible secret key, or the node permissions configured inSTORAGE_S3_ENDPOINTare insufficient, resulting in signature generation failure. - Phenomenon: The knowledge base disk usage continues to grow without automatic cleanup. Cause: No automatic archiving strategy has been configured for daily updated data, and the connection limit for
DB_MAX_LINKhas not been set, resulting in cache accumulation. - Phenomenon: The front-end interface model vendor icon loading fails. Cause:
FE_DOMAINhas not been configured as the official domain name of the government service portal, triggering cross-origin resource sharing blocking.
How to confirm the configuration is correct
- Log in to the storage monitoring panel in the FastGPT v4.17.0 backend, confirm that the connection count of the instance bound to
REDIS_URLis stable within the configuration range of300–500 connections. - Upload a joint handling application form, check whether the file access link can be generated normally, and that access matches the permission rules of the government platform.
- View the static resource loading logs of the front-end page, confirm that there are no cross-domain error messages under the domain name configured in
FE_DOMAIN. - Trigger a daily updated data synchronization task, check whether the update of the joint handling item list is completed normally, with no error logs.
