What This Category of Data Looks Like
Aerospace equipment investment research data primarily comes from official announcements of model development progress, public space launch mission data, industry standards and specifications, public telemetry parameter reports, publicly available technical white papers in the defense aerospace sector, and a small number of authorized internal test data. The data includes long-form documents such as overall model design reports and launch mission briefings, as well as structured technical parameter tables and time-series telemetry data. Fields include model code, mission time, technical parameter values, test operating conditions, and compliance standard numbers. Parameter units use specialized aerospace units such as kilonewtons, kilometers, and tons.
What Constraints These Characteristics Place on Database and Operations
The high proportion of long documents requires the database to support large field storage and full-text indexing to avoid retrieval delays. A mix of unstructured documents and structured time-series data requires adaptation to both document and time-series storage logic, which increases storage selection and operational complexity. Irregular bulk updates and real-time task data imports require operational processes to support incremental synchronization and breakpoint resumption. The strong association between fields and units requires supporting metadata management mechanisms to ensure unit consistency and field accuracy during parameter queries.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single aerospace equipment model design reports and launch mission documents are typically large in size; this setting prevents upload truncation |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long documents require longer parsing time; this setting prevents premature termination of parsing due to timeout |
RECALL_TOP_K | Top 8–12 entries | Investment research documents usually contain a large number of professional parameters; sufficient relevant fragments must be retrieved to cover complete technical logic |
DB_CONNECTION_POOL_SIZE | 32–64 | Mixed storage scenarios require support for concurrent document queries and time-series data reads |
VECTOR_DIMENSION | 1536 | Matches the output dimension of general vectorization models to ensure consistency in vector retrieval for parameters and documents |
SYNC_INCREMENTAL_ENABLE | Enabled | Adapts to scenarios of irregular bulk updates and real-time task data imports for aerospace equipment data |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: Structured parameter query results are empty after database migration. Cause: Metadata field mapping for aerospace equipment data was not synchronized, leading to incorrect mapping of model code and unit fields from the original database to the new database.
- Symptom: A
413 Request Entity Too Largeerror is triggered when uploading large model design reports. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration was not adjusted, and the small-volume limit for general scenarios was retained. - Symptom: Write timeouts occur during high-concurrency import of telemetry time-series data. Cause: The
DB_CONNECTION_POOL_SIZEconfiguration was not adjusted, and the connection pool is insufficient to support high-frequency time-series data writes.
How to Confirm Configurations Are Properly Set
- Upload an aerospace equipment model design report, check that document chunks are complete after parsing with no truncated content.
- Initiate a structured parameter query, verify that the returned results include correct model code, unit fields, and parameter values.
- Simulate bulk import of time-series telemetry data, check that write success rate and latency meet business expectations.
- Trigger an incremental synchronization task, verify that only newly updated data is correctly imported with no duplicate writes.
