What data for this category looks like
Data sources for this category include the road transport administration system, the national road transport vehicle dynamic information public service platform, and the vehicle and personnel database. Data update frequency is daily. Daily documents include business license application materials, vehicle technical files, driver qualification materials, safety production management systems, and original and duplicate copies of road transport business licenses. Data fields cover license number, vehicle plate number, personnel qualification certificate number, business site address, business scope, and more. There is no unified batch export template. Multi-source associated data must be integrated per single license item.
What constraints these characteristics impose on database and operations workflows
Daily updated data must synchronize multi-source interfaces via scheduled tasks. Set reasonable concurrency limits to avoid triggering platform rate restrictions. Multi-source data must be integrated and associated by license subject. Databases must support cross-table association query logic. Non-standardized business documents must be split into structured fields and unstructured text for separate storage, to avoid data redundancy. The number of materials associated with a single license varies widely. Database connection pools must adapt to dynamic load changes. Operations teams must regularly verify data consistency. Cross-system synchronization delays can cause ledger data to not match actual license status, leading to issues such as license rejection.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|
Reference only; verify against the target FastGPT release and deployment documentation.
| PG_URL | postgresql://fastgpt:xxxx@db-host:5432/trans_license_stats | Stores standardized license statistics fields, supports efficient batch summary and conditional queries, and meets the structured statistical requirements of industry ledgers |
| DB_MAX_LINK | 20–30 | Adapts to the dynamic load of daily multi-source data synchronization, avoids connection exhaustion or idle resource waste, and balances performance and resource usage |
| REDIS_URL | redis://redis-host:6379/1 | Caches frequently queried basic license information to reduce repeated database requests, and stores status markers for scheduled synchronization tasks |
| Database backup cycle | 2:00 AM daily | Matches the daily data update rhythm, avoids occupying system resources during business peak hours |
| Data archiving strategy | Retain license ledger data from the past 3 years | Complies with industry regulatory requirements while controlling storage capacity overhead for long-term database use |
Three common configuration mistakes
- Phenomenon: When executing ledger summary tasks in batches, some nodes have no execution logs. Database connection pool logs show connection exhaustion. Cause:
DB_MAX_LINKis not configured to adapt to concurrent requests, so new tasks cannot obtain available database connections. - Phenomenon: After the service starts, a MongoDB version security vulnerability error is returned, and database connections cannot be established. Cause: The used MongoDB version is lower than the official security patch version. Upgrade to a stable version with the fix applied.
- Phenomenon: An incompatible driver error occurs when attempting to configure a specialized database for ledger data storage, and data writing cannot be completed. Cause: The current version only supports standard database connection protocols, and does not adapt to non-standard database drivers.
How to confirm configurations are correct
- Execute a single-license ledger summary test task, check database connection logs, and confirm that the current connection count does not exceed the configured
DB_MAX_LINKthreshold. - Log in to the database management interface, check the databases corresponding to
MONGODB_URIandPG_URL, and confirm whether there are license data entries synchronized on the current day. - Trigger a scheduled synchronization task, check the cache space corresponding to
REDIS_URL, and confirm that the task status marker has been written correctly. - Export test ledger data for licenses, and confirm that the exported fields match the structured fields of business documents.
