What the data for this category looks like
Logistics yield rate-related data mainly comes from logistics transportation management systems, fuel supply APIs, toll settlement systems, and terminal delivery scheduling systems. There are two update cadences: trunk line transport batch data updates daily, and terminal delivery order volume data updates hourly. The data format is structured CSV or JSON, with each row corresponding to a carrier batch. The included fields are: line ID, batch number, departure time, actual revenue (unit: yuan), actual operating cost (unit: yuan), actual loading volume (unit: cubic meters), rated loading volume (unit: cubic meters), total fuel consumption (unit: liters).
What constraints these characteristics impose on the "tool calling and plugins" workflow
The need to access multiple data sources requires plugins to support parallel calls to different API interfaces, to avoid overall latency caused by serial calls. Differences in update frequencies across data sources require configuring differentiated scheduled trigger parameters to adapt to hourly incremental updates and daily full updates respectively. Fields include multiple units such as volume, amount, and time, so the plugin's parameter validation module must support automatic multi-unit conversion to avoid errors from cross-unit calculations. Logistics data has strong batch association attributes, so the batch ID must be passed as an associated parameter during tool calling to prevent mixing of data from different batches.
How to set the configurations
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
PLUGIN_TRIGGER_INTERVAL | 300 seconds or 86400 seconds | Adapts to the different update cadences of hourly terminal delivery updates and daily trunk line transport updates |
MINIO_UPLOAD_BUCKET | logistics-yield-report | Uniformly stores plugin outputs, intermediate calculation results, and log files related to logistics yield rate |
DATABASE_CONN_TIMEOUT | 15 seconds | Adapts to the response delay range of most logistics data sources to avoid unnecessary waiting |
PARSE_FIELD_MAPPING | {"line_id": "line_id", "actual_revenue": "revenue", "batch_number": "batch_no"} | Matches the field naming conventions of data sources to complete automatic data mapping |
PLUGIN_PARSE_MAX_RECORDS | 500 records | Matches the maximum number of records in a single batch of logistics data to avoid out-of-memory errors |
API_DATA_ID_POLICY | Generated by batch number + timestamp | Ensures that the dataId of each logistics batch is unique and traceable |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: A
500 Internal Server Erroris prompted when installing the database connection plugin. Cause: The environment variables for the database driver are not configured, or the database connection string contains unescaped special characters. - Symptom: The MinIO storage plugin fails to write data normally, and saved log files cannot be viewed. Cause: The correct storage bucket name is not specified, or the storage bucket permission is configured as read-only.
- Symptom: No
dataIdfield is obtained when calling the API interface to fetch data, and the returned result is empty. Cause: TheAPI_DATA_ID_POLICYconfiguration is not enabled, or the generation policy is not associated with the logistics batch ID.
How to confirm the configuration is complete
- Execute the plugin's built-in test script, pass the parameters of the test batch, and check whether the returned result contains all configured fields, with units matching the annotations of the data source.
- Log in to the MinIO console, check whether the
logistics-yield-reportstorage bucket exists, and whether test-generated log files and intermediate data are present. - Call the test interface of the database connection plugin, check that the returned connection status code is
200 OK, with no timeout or permission errors. - Call the public API interface, check whether the returned result contains the
dataIdfield, and the field value matches the test batch number and timestamp.
