What the Data for This Category Looks Like
Aerospace equipment investment research data primarily comes from public project approval announcements of military aerospace groups, test verification reports, industry standard specifications, public research reports from third-party military aerospace consulting firms, and public observation records of space launch missions.
Its update rhythm fluctuates with project milestones. Sudden updates trigger on core project approval or launch mission milestones. Regular research reports are updated quarterly. Industry standard documents have longer update cycles.
Most documents are long texts, containing technical parameter fields such as thrust, orbital altitude, and launch window. Units include kilonewtons, kilometers, and seconds. Some documents include tabular payload configuration lists.
What Constraints Do These Characteristics Impose on Deployment and Upgrade
The characteristics of aerospace equipment investment research data — long texts, high sudden update frequency, specific technical field units — impose multiple constraints on deployment and upgrade workflows.
Long text documents extend parsing time, requiring adapted longer parsing timeout settings. Sudden updates require deployments to support incremental synchronization and version rollback, to avoid service interruptions caused by full rebuilds. Specific technical field unit rules require the knowledge base parsing process to retain the binding relationship between fields and units, with no arbitrary splitting. Frequent version iteration demands require upgrade workflows to support configuration migration from historical versions, to avoid parsing errors caused by version differences.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Most aerospace investment research documents are long texts, with parsing times longer than general scenarios. 600 seconds covers parsing needs for most large test reports. |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Aerospace test reports and remote sensing dataset files have large sizes. 2000 MB meets most single-file upload requirements. |
CHUNK_MAX_SIZE | 1500 characters | Aerospace technical documents contain numerous parameter tables and long sentences. 1500-character chunking preserves the complete association between parameters and context. |
RECALL_TOP_N | Top 8 entries | Aerospace investment research data has high density of professional terminology. Retrieving 8 entries covers associated information for core technical parameters. |
SIMILARITY_THRESHOLD | 0.75–0.85 | Balances retrieval precision and coverage, adapting to weak matching retrieval needs in professional domains. |
ENABLE_INCREMENTAL_SYNC | Enabled | Adapts to the sudden update demands of aerospace investment research data, reducing service pressure from full synchronization. |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Errors
- After upgrading to version 4.9.10, the global variable configuration panel only displays two optional values. The cause is that this version adjusted the validation rules for global variables, only retaining built-in basic variable types, and did not maintain compatibility with the legacy configuration format for custom global variables.
- After cross-version upgrade from 4.8.10 to 4.9.10-fix2, technical parameter fields in some knowledge bases are missing. The cause is that different versions of the document parser have different binding rules for technical fields, and version-compatible migration was not performed.
- Uploading a single large aerospace test report triggers a timeout error, with the log showing
PARSE_FILE_TIMEOUT. The cause is that the parsing timeout configuration item was not adjusted, and the default value cannot cover the parsing time of long text documents.
How to Verify Correct Configuration
- Upload a long-text test report from the aerospace field, and verify that the parsed chunk length matches the configured value.
- Trigger an incremental synchronization task, and verify that the system only syncs updated documents and does not reprocess already parsed historical files.
- View the global variable configuration panel, and confirm that the number of displayed custom variables matches the expected configuration.
- Upload a single file of size meeting business requirements, and confirm that the upload process does not trigger abnormal errors.
