What the data for this category looks like
Daily business documents for this category include maintenance plans, patrol logs, defect disposal reports, road construction permits, and road damage compensation forms. Data sources include highway maintenance management systems, bridge and tunnel monitoring systems, road patrol systems, and traffic flow monitoring data. The update frequency is daily. Document fields include facility ID, location coordinates, disposal status, permit identifier, and some documents have attached image or numeric auxiliary data. Documents are stored categorized by business process link, with no unified global field template. Document export formats differ across systems.
What constraints these characteristics impose during deployment and upgrade
High-frequency daily multi-source data requires stable database connections and incremental synchronization mechanisms to avoid data synchronization delays or loss. Unformatted business documents with no unified template require compatible parsing rules for more custom fields during upgrades, to prevent some documents from being unrecognized by the system. Sensitive data related to road construction and road damage requires compliant encryption and access control rules during deployment, to ensure data security. Differences in interface formats across business systems require reserved adaptation interfaces for multi-source data access during upgrades, avoiding the need to rebuild data synchronization logic when adding new data sources.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 connections | Matches concurrent connection needs for daily multi-system data synchronization, prevents connection pool exhaustion that causes sync interruptions |
MONGODB_URI | Configure per the data storage path of business systems, add read-write separation parameters | Stores multiple types of business documents; read-write separation improves query and write efficiency for patrol logs and defect disposal reports |
REDIS_URL | Configure cache rules with a 600-second expiration time | Caches frequently queried road property location and construction permit information, reduces repeated query pressure on the database |
FILE_TOKEN_KEY | Generate a dedicated key per internal data encryption specifications | Encrypts and stores sensitive documents such as road construction permits and road damage compensation forms, ensures business data security |
STORAGE_S3_ENDPOINT | Configure per the cloud storage node of the deployment region | Stores large files such as maintenance plans and patrol images locally to improve document access and loading speed |
Three common mistakes
- Phenomenon: Database connection timeout errors occur after deployment, with status code 503. Cause: The
DB_MAX_LINKconfiguration was not adjusted based on daily data volume, and the connection pool cannot support concurrent requests from multi-system synchronization. - Phenomenon: Some patrol logs cannot parse field content after upload. Cause: Document formats exported by different business systems were not adapted, and only a single document parsing rule was configured, leading to unrecognized custom fields.
- Phenomenon: Some sensitive documents cannot be accessed normally after upgrade. Cause: The
FILE_TOKEN_KEYconfiguration was not backed up in advance; changes to the encryption key prevent decryption and reading of previously stored sensitive documents.
How to confirm configurations are applied correctly
Reference only; verify against the target FastGPT release and deployment documentation.
- Run the FastGPT built-in database connection test tool, confirm that the connection pool connection count matches the
DB_MAX_LINKconfiguration value, and no connection timeout errors occur. - Upload a standard defect disposal report document, verify that the fields parsed by the system match the original document content, with no missing or incorrect fields.
- Trigger a manual incremental data synchronization task, confirm that patrol logs and traffic flow data pulled from each business system are fully synchronized to the platform.
- Access the frontend deployment address, confirm that the page loads normally, and that sensitive document downloads require a valid access token, with no direct public access available.
