What the data for this category looks like
Optical optoelectronics industry financial report data is mainly sourced from public periodic reports disclosed by domestic and overseas stock exchanges, and monthly supply chain data from third-party industry monitoring institutions. Data update cadence falls into two categories: quarterly concentrated financial report disclosures and monthly supply chain data updates. Document structures include consolidated financial statements, detailed operating statements by business segment, special explanations on production capacity and shipment volume, and more. Core fields include revenue amount, shipment volume, production capacity scale, R&D investment amount, and others, with units mostly in 100 million yuan, 10,000 units, 10,000 square meters, and similar units.
What constraints do these characteristics impose on deployment and upgrade
Multi-source heterogeneous data sources require adapting to mixed access of structured financial reports and unstructured monitoring data during deployment, and multi-format parsing adapters must be configured. The high-frequency update feature requires enabling incremental indexing to avoid excessive time spent on full index reconstruction. There are many detailed data entries by business segment, so document splitting must balance the integrity of business logic, and segment parameters need to be adjusted to avoid destroying segment-related content. Some data requires cross-cycle comparative analysis, so a data version storage path must be configured during deployment to retain historically disclosed data.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Optical optoelectronics financial reports often include multi-page production capacity details and supply chain attachments, so single-file volume is usually large, requiring support for large file uploads |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Structured parsing of long financial report documents requires processing multi-segment data, so the timeout period must cover the complete parsing process |
maxContext | 8000–12000 characters | The content of optical optoelectronics financial reports by business segment is dense, requiring a sufficient context window to carry complete business logic |
RECALL_TOP_K | Top 8–12 entries | There are many business-specific fields, so a sufficient number of associated data needs to be recalled to support comparative analysis |
SYNC_CRON_EXPRESSION | 0 0 2 * * * | Synchronize newly disclosed financial reports and industry data daily at 2 AM, adapting to quarterly and monthly update cadences |
PARSE_CHUNK_SIZE | 800–1200 characters | Adapt to the length of business paragraphs in optical optoelectronics financial reports, avoiding splitting that destroys segment-related logic |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require on-site analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Issue: When deploying version 4.8.9 using docker-compose, a "File parsing failed" prompt pops up when creating a new knowledge base. Cause: The
UPLOAD_FILE_MAX_SIZEparameter was not adjusted, and the volume of optical optoelectronics financial report attachments exceeded the default limit. - Issue: After private deployment on Linux, the number of business data recalled by the knowledge base does not cover multiple business segments. Cause: The
RECALL_TOP_Kparameter was not adjusted, and the default number of recalled entries is too small to support multi-dimensional analysis. - Issue: After configuring an English prompt and an English knowledge base, the locally deployed llama3.1 still outputs Chinese. Cause: The
LLM_DEFAULT_LANGUAGEparameter was not configured to English, or the corresponding environment variable was not mounted correctly.
How to verify the configuration is correct
- Upload a single optical optoelectronics financial report PDF with a volume not exceeding 1000 MB, check that the parsing task completes within 600 seconds with no error logs.
- Manually trigger the scheduled synchronization task, check that both newly added data from incremental synchronization and historically disclosed data have been stored in the vector database.
- Initiate a financial report analysis request, check that the number of recalled business data falls within the configured 8–12 entry range.
- Verify that the model output language matches the prompt configuration, with no language drift or garbled characters.
