What the data for this category looks like
Data for this category comes from three main sources: public announcements of listed companies, public information from national defense science, technology and industry authorities, and official disclosures from military industry groups. Update cadences fall into two categories: scheduled and unscheduled. Annual reports are disclosed before April each year. Quarterly reports are released within one month after the end of each quarter. Temporary matters such as major equipment procurement and production capacity adjustment are disclosed within two trading days after the event occurs. A single financial report document includes multiple modules: financial statements, management discussion and analysis, major contract disclosures, and others. Core fields include weapons and equipment order contract value, military product gross profit margin, core equipment production capacity, and more. Amount units are primarily ten thousand yuan or hundred million yuan in RMB. Production capacity units are commonly marked as sets/year.
Constraints on HTTP interfaces and external systems
Ordnance equipment financial report data has three key characteristics: dispersed sources, mixed update cadences with unscheduled events, and specialized military terminology plus specific unit markings. These characteristics create multiple constraints for HTTP interfaces and external systems. Multi-source data integration requires support for multiple authentication protocols. This adapts to the interface permission rules of different data sources. Unscheduled temporary announcement pull requests require interfaces to support dynamically adjustable concurrency thresholds. The specificity of professional fields and units requires interfaces to support custom field mapping rules. This avoids data distortion caused by standardization processing. Long document processing requires interfaces to configure reasonable segment lengths and timeout parameters. This adapts to financial report files of different sizes.
How to configure the settings
The following table lists configuration items, recommended settings, and their rationales:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
external_data_source_auth_type | api_key + custom header | Ordnance equipment financial report data sources often require exclusive authentication keys. Custom headers can adapt to authentication rules of different platforms. |
max_concurrent_requests | 20–30 | Unscheduled temporary announcement pull requests require stable concurrency support. This avoids exceeding the rate limiting thresholds of external data sources. |
field_mapping_rule | custom mapping + professional terminology dictionary | Ordnance equipment financial reports include exclusive field names. External fields must be mapped to unified analysis fields. |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | A single financial report document can reach hundreds of thousands of characters. Sufficient parsing time must be reserved. |
chunk_size | 800–1200 characters | Ordnance equipment financial reports contain many professional paragraphs. Segment length adapts to context association requirements for long texts. |
UPLOAD_FILE_MAX_SIZE | Calibrated through actual testing | The file size of single ordnance equipment financial reports varies widely. Thresholds must be adjusted based on actual file scale. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Scenario: The interface returns a
429 Too Many Requestsstatus code, and data is missing when pulling temporary announcements. Cause: Themax_concurrent_requestsparameter was not adjusted to meet unscheduled pull requirements for ordnance equipment financial reports, exceeding external data source rate limiting thresholds. - Scenario: A
413 Payload Too Largeerror is returned when uploading financial report files, or file parsing progress stalls. Cause: TheUPLOAD_FILE_MAX_SIZEparameter was not adjusted to a value suitable for financial report files, or file chunked upload rules were not configured. - Scenario: Professional field names are inconsistent in analysis results, or unit markings are incorrect. Cause: The
field_mapping_rulewas not configured, and general field mapping rules were used directly to process exclusive fields and units for ordnance equipment.
How to verify correct configuration
- Call the external data source pull interface. Check if returned fields match the preset
field_mapping_rule, and verify unit markings are correct. - Simulate unscheduled temporary announcement pull requests. Check if concurrent interface request counts meet business requirements, and no rate limiting errors are triggered.
- Upload a single typical financial report file. Check if parsed segment lengths match the
chunk_sizesetting, and no content truncation or timeout errors occur. - Check execution logs for scheduled pull tasks. Confirm that trigger logic for both scheduled reports and temporary announcements works correctly.
