What the Data for This Category Looks Like
Data sources include general financial industry defense and aerospace research report platforms, internal public technical documents from aerospace systems, and official aerospace launch mission announcements. These resources support financial professionals in analyzing investment logic for the aerospace equipment track. Update rhythm follows aerospace equipment model milestones. Updates are triggered alongside new project initiation, launch missions, annual industry summaries, and similar events. Most documents are multi-chapter technical content, containing fields such as model parameters, performance indicators, R&D progress, and supporting systems. Most fields include professional units: thrust is measured in kilonewtons (kN), orbit altitude in kilometers (km), and payload mass in kilograms (kg). Some documents include charts and formulas.
Constraints on Deployment and Upgrade Posed by These Characteristics
Multi-chapter long documents, professional units, and formulas require retaining metadata parsing capabilities during deployment. This prevents loss of units and technical parameters. Irregular update rhythms require upgrade processes to support quick adaptation to new data source formats. Fixed parsing rules should be avoided. Large individual document sizes and non-text elements require adjusting file upload and parsing timeout thresholds during deployment. This prevents parsing interruptions. Standardization requirements for professional fields require synchronously updating vector index field mapping rules during upgrades. This ensures accurate parameter matching during retrieval.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000–2000 MB | Individual aerospace equipment research report documents are typically larger than general documents, so this range accommodates long document upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 600–900 seconds | Long documents include professional formulas and charts, so parsing takes longer than general text. An extended timeout threshold is required |
TEXT_SPLITTER_CHUNK_SIZE | 800–1200 characters | Aerospace research reports contain technical jargon and long sentences. Segmentation must cover complete technical statements to avoid semantic fragmentation |
Recall count | Top 8–12 entries | Professional parameters in aerospace research reports require precise matching. Too many recalled entries introduce irrelevant content and reduce retrieval accuracy |
Similarity threshold | 0.75–0.85 | Semantic similarity of professional terms must be strictly controlled. This avoids recalling irrelevant research reports with low matching scores |
DB_CONNECTION_TIMEOUT | 30 seconds | Network latency between the database and application during private deployment must accommodate subsequent processes of long document parsing |
The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing values.
Three Common Misconfigurations
- Symptom: A
database connection failederror appears in post-startup logs, and platform login is unavailable. Cause: TheDB_PASSWORDenvironment variable is not configured correctly, or the container image is not rebuilt after modifyingcompose.yaml, resulting in ineffective configuration. - Symptom: After modifying
MYSQL_ROOT_PASSWORDincompose.yamland restarting the container, the root password does not take effect. Cause: The previously created database volume is not deleted. The original database configuration is retained in the volume, and the new configuration is not loaded. - Symptom: When accessing the platform with an older version browser, the interface fails to load or function buttons become invalid. Cause: The static resource strategy compatible with older browsers is not configured, or polyfill support for modern JavaScript syntax is not enabled. Modern code fails to parse in this scenario.
How to Verify Configuration Correctness
- Upload an aerospace equipment research report document, and check if the parsed metadata includes professional units and technical parameter fields. This confirms the parsing function operates normally.
- Trigger a research report retrieval, and verify that the number of returned results and similarity matching degree conform to the preset configuration rules.
- Restart the container, and check logs for no database connection errors. This confirms configuration loading is normal.
- Access the platform page using an older version browser, and verify that core functions load normally. This confirms the compatibility configuration takes effect.
