What data for this category looks like
Data related to coke comes primarily from the Dalian Commodity Exchange coke futures market system, major domestic coastal port spot quotation platforms, and industry supply and demand monitoring institutions. Data updates follow three schedules. Futures market data is pushed in real time. Spot quotations are updated daily. Industry supply and demand reports are released monthly. Most public documents are structured tables, with fields including delivery grade, daily settlement price, port pickup price, total port inventory, average daily shipment volume, and others. Units are uniformly yuan/ton and ten thousand tons. There is no highly nested unstructured content.
What constraints these characteristics impose on forms and interactions
The high-frequency updates of coke data require form interaction links used for marketing and customer acquisition to support real-time data pulling and refreshing. This prevents information lag caused by cached expiration. Structured fields and fixed enumeration values require form input items to preset compliant options. Free text input is prohibited. This prevents non-standard data from being collected, and ensures collected user demands meet industry specifications. The need for parallel calls to multiple data sources requires interaction nodes to configure reasonable timeout thresholds. This prevents individual interface lag from slowing the overall process, which affects marketing content generation efficiency. Unified unit specifications require form validation rules to forcibly match the formats yuan/ton and ten thousand tons. This blocks input that does not meet unit requirements. It also needs to adapt to field mapping logic across different data sources, ensuring consistent display of cross-source data.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
formRefreshInterval | 300 seconds | Coke spot quotations are updated daily. A 300-second refresh interval balances information timeliness and server load |
formFieldRestrictMode | Enumeration binding | Fields such as coke delivery grade and unit follow fixed industry specifications. Enumeration binding prevents non-standard input |
apiRequestTimeout | 10 seconds | Three types of data sources (futures, spot, port) must be called simultaneously. Single-interface timeout control prevents overall process lag |
inputValidationUnit | yuan/ton, ten thousand tons | Standard units for coke data are yuan/ton and ten thousand tons. Forced matching blocks non-compliant input |
parallelApiCallCount | 3 | Three independent data source interfaces must be called in parallel. This value improves loading efficiency without exceeding interface call limits |
formSubmitRetryTimes | 2 | Network fluctuations may cause form submission failures. Limited retries improve submission success rate |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: Downstream nodes throw errors after form submission, prompting that input fields are empty. Cause: No mapping rule between form fields and global variables is configured. This causes coke purchase volume entered in the form to not be correctly written to global variables.
- Symptom: The coke data source returns a
429 Too Many Requestsstatus code. Cause: Parallel API call volume is not limited. Concurrent requests exceed the call limit of the data source interface. - Symptom: Form enumeration options are not synchronized with the latest coke delivery grades. Cause: The form refresh interval is configured too long, and does not match the daily update schedule of coke spot quotations.
How to confirm proper configuration
- Manually trigger form refresh, check whether enumeration options match the current publicly available coke delivery grades in the industry, and verify that the refresh cycle matches the data update schedule.
- Submit input content that does not meet standard units, confirm whether the system blocks the input, and verify that the input validation rule takes effect.
- View node logs, confirm that the number of parallelly called data source interfaces matches the configured
parallelApiCallCountvalue, and there are no excess requests. - Simulate network fluctuation scenarios, submit the form, confirm that the retry mechanism is triggered, and the number of retries matches the configured
formSubmitRetryTimesvalue.
