What the data for this category looks like
Data for this category comes from three official data sources. These are the road transport administration management system, the national public service platform for dynamic information of road transport vehicles, and the vehicle and practitioner database. The update frequency is daily. Documents processed daily include business license applications, vehicle technical files, driver qualification materials, work safety management systems, and road transport business licenses. Corresponding fields include license number, vehicle license plate, qualification certificate number, safety system clauses, site certification materials, and others. The data structure includes both structured fields and unstructured document content.
What constraints these characteristics impose on the deployment and upgrade phase
High-frequency daily updated multi-source data requires stable multi-data source connection and synchronization scheduling rule configurations during deployment. The mixed structured and unstructured data structure requires separate storage configuration adaptations for relational databases and document databases. The data verification link involves multiple qualification material types. Sufficient database connection resources must be reserved during deployment to avoid exhaustion. Cross-version upgrades must follow the version sequence strictly. License data schemas have associated changes across different versions. Skipping intermediate versions causes data verification failures.
How to set configurations
These configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 10–15 | Adapts to the scenario of daily high-frequency synchronization of multi-source data, avoiding database connection exhaustion |
MONGODB_URI | Fill in the connection string dedicated to the road transport document database | Stores unstructured document content such as license applications and work safety management systems |
PG_URL | Fill in the connection string for the structured database of vehicles and practitioners | Stores structured fields such as license number, vehicle license plate, and qualification certificate number |
REDIS_URL | redis://:{custom password}@{server address}:6379/0 | Caches frequently queried license status and driver qualification verification results to reduce database load |
STORAGE_S3_ENDPOINT | Fill in according to the local object storage service address | Stores attachment documents such as scanned copies of vehicle technical files and site certification materials |
Three common mistakes
- Skipping intermediate non-script versions during upgrade, resulting in
schema mismatcherrors. The cause is failure to execute upgrade scripts in version order, leading to incompatible data structures - Server configuration not matching data volume, resulting in synchronization timeout (status code 504). The cause is failure to adjust connection pool configurations such as
DB_MAX_LINKbased on daily synchronized data volume - Misusing the knowledge base collection tag function, leading to invalid query result filtering. The cause is failure to bind exclusive tags for road transport business licenses to corresponding data sources, and failure to configure tag synchronization rules
How to confirm the configuration is complete
- Run
docker logs fastgpt, check that database connection logs have noconnection refusedortimeouterrors - Trigger a manual data synchronization task, confirm that the synchronization progress completes with no abnormal field prompts
- Test querying driver qualification information, confirm that the returned results include preset structured fields and unstructured documents
- Log in to the Redis console, check that key-value pairs such as cached license status and qualification verification results exist
