What the data for this category looks like
Optical module financial report data primarily comes from publicly disclosed quarterly, semi-annual, and annual financial reports of manufacturers. It is supplemented by market monitoring reports released by industry associations. Data updates follow a fixed quarterly schedule. Annual financial reports add full-year dimension data. Each individual financial report document includes fields such as revenue scale, shipment volume, average module price, gross margin, and R&D investment. Their respective units are ten thousand yuan, ten thousand units, USD/unit, percentage, and ten thousand yuan. Some overseas manufacturers' financial reports include revenue data converted using exchange rates.
What constraints these characteristics impose on deployment and upgrade
Fixed quarterly update schedules require configuring periodic data sync tasks during deployment to avoid unnecessary real-time indexing resource consumption. Multi-field structures with differentiated units require pre-configured field mapping and unit conversion rules to prevent data anomalies during import. Longer individual financial report documents require adjusting segmentation thresholds and context window parameters during parsing to avoid truncating core business data. Cases where overseas manufacturers' reports include exchange rate converted data require additional configuration of an exchange rate parsing module, increasing deployment dependencies. When upgrading versions, compatibility with historical financial report field formats is required to prevent existing data from failing to load normally.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Individual optical module financial report documents have large file sizes; default timeout durations are insufficient for complete parsing |
UPLOAD_FILE_MAX_SIZE | 500 MB | Individual financial report PDF documents typically do not exceed 100 MB; reserving reasonable margin prevents upload failures |
chunk_size | 1200–1500 characters | Financial reports contain multi-field long text; segmentation length adapts to field completeness and recall accuracy |
RECALL_TOP_N | Top 8 entries | Core business fields of financial reports are concentrated; excessive recall introduces non-core redundant data |
SYNC_CRON_EXPRESSION | 0 0 2 * * 1 | Disclosure schedule for optical module manufacturer financial reports is fixed 1-2 weeks after quarter end; weekly sync covers the latest data |
PARSE_CHUNK_OVERLAP | 150 characters | Business correlations exist between financial report fields; overlapping segments preserve contextual logical integrity |
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 targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Deployment cannot connect to external interfaces, and the web interface displays connection timeout. The cause is that a static container address is not configured. Container addresses change after each restart, causing FastGPT to fail to fix the call path.
- Knowledge base indexing completes, but search results are empty or have missing fields. The cause is that field mapping rules for financial reports are not configured. Unit or field name mismatches occur during import, so parsed text cannot be correctly recalled.
- Document parsing tasks time out and fail, and logs return
504 Gateway Timeout. The cause is that thePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. Long document parsing exceeds the default timeout limit.
How to confirm configuration is complete
- Manually upload a single historical financial report document, check if the parsed segmented content fully retains core fields with no truncation or garbled text.
- Run a manual sync task once, check if there are any records of field conversion failures or file parsing exceptions in the sync logs.
- Configure a test external interface call, verify that interface connectivity is stable and unaffected by container restarts.
- Initiate a simulated search query, confirm that returned results include core financial report fields and the quantity matches the expected configuration.
