What the Data for This Category Looks Like
Data for this category comes from aggregated output of core trading systems, valuation accounting systems, and external market quote interfaces. Full datasets are generated at fixed daily times. The maximum delay is 4 hours after the end of the day’s business. Data documents use standard JSON array format. Each entry includes four core fields: unique target code, statistical cycle identifier, yield calculation value, and data update timestamp. Units follow standardized financial accounting base units. No custom format fields are included. All fields are required.
Constraints Imposed on HTTP Interfaces and External Systems
Multi-source aggregated data sources require interfaces to support cross-system authentication and field mapping. This prevents format conflicts across different data sources. Daily fixed update schedules require external systems to configure scheduled pull jobs. Reserve data generation buffer time to avoid pulling incomplete datasets. JSON array structure requires interface responses to strictly follow the preset format. Parsing failures will occur otherwise. Standardized accounting units require interfaces to unify field output formats. This prevents downstream system calculation errors caused by inconsistent units. Full dataset size requires interfaces to support pagination query parameters. This prevents timeouts caused by overly large single request responses.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
external_data_fetch_timeout | 300 seconds | Matches the data generation buffer duration for this category, avoids timeouts triggered by unready data |
api_authentication_method | Signature verification + API key | Adapts to security requirements for multi-source data integration, prevents unauthorized access to aggregated sensitive data |
response_parse_schema | Preset JSON array template | Strictly matches the data structure of this category, avoids parsing failures in downstream systems |
page_size | 100 items per page | Adapts to full dataset size, balances transmission efficiency and parsing time for single requests |
data_retry_times | 3 retries | Addresses network fluctuations or temporary unready data scenarios, reduces synchronization failure probability |
unit_conversion_rule | Normalize to base units | Unifies field output formats, prevents downstream system calculation errors caused by unit discrepancies |
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. It is recommended to test on your own samples before finalizing.
Three Common Mistakes
- A
code:514error is returned when calling the interface. Cause: No dedicated data source authentication rule for this category is configured, or authentication parameters are not passed as required, leading to interface verification failure. - Interface return results cannot be parsed normally by downstream systems. Cause: The
response_parse_schemaconfiguration is not enabled, raw multi-source data is received directly, and no format normalization processing is completed. - Scheduled pull jobs frequently trigger timeouts. Cause: The
external_data_fetch_timeoutconfiguration is not adjusted, the default short timeout duration is used, which does not match the data generation cycle of this category.
How to Confirm Proper Configuration
- Execute a single curl test request, check if the returned JSON array structure matches the preset
response_parse_schema. - View interface call logs, confirm that authentication parameters are passed correctly, and no
code:514error records exist. - Compare the pulled field units with the preset
unit_conversion_rule, confirm that the format is unified. - Test the pagination pull function, confirm that returned data across different pages has no duplicates or missing entries.
