What Data for This Category Looks Like
Industrial metal data sources include industry association public reports, real-time APIs of spot trading platforms, and settlement data from futures exchanges. Updates follow three rhythms: spot quotes update in real time during trading days, industry inventory data updates weekly, and futures settlement prices update during trading sessions. Documents are structured single entries with fields including product name, standard specification, production origin, benchmark transaction price, total inventory, downstream operation-related indicators, and more. Units correspond to: product name, specification code, origin name, yuan/ton, 10,000 tons, and quantitative statistical values, respectively. Document content length increases as the number of covered categories grows. Bulk-imported industry weekly report documents are generally large in size.
How These Characteristics Impact Deployment and Upgrade
The high-frequency real-time update feature of industrial metal data requires scheduled pull task intervals configured during deployment to match data source update cycles. This prevents data lag from harming marketing content timeliness. The structured feature with multiple fixed-specification fields requires unified field mapping rules to be configured when upgrading the knowledge base. This stops non-standard specification data from being mixed in and causing parsing failures. As data entries expand with the number of covered categories, and bulk-imported documents are generally large, adjust the sharding threshold when upgrading the vector database. This adapts to the maximum data volume of a single batch import. The requirement for real-time market access requires reserving adjustment space for API timeout parameters during deployment. This accommodates response delays from different data sources.
How to Set Configuration Values
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large industry weekly reports and spot database files for bulk-imported industrial metal data takes significant time. Sufficient parsing time must be reserved |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Bulk-imported industrial metal industry documents are generally large in size. The maximum upload limit must be adapted |
maxContext | 800–1200 characters | Core market data fields for industrial metals are moderately sized. Excessively long contexts reduce marketing content generation efficiency |
Recall count | Top 8 entries | Industrial metal marketing content needs to cover multi-dimensional market data. Too many recalled entries lead to content redundancy |
Similarity threshold | 0.75 | Low-correlation historical market data must be filtered out to retain highly matched marketing materials |
Chunk size | 500 characters | Single-segment content of industrial metal documents has a clear structure. Segmentation enables precise recall |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are influenced by material form, data volume and business rules. Specific issues require case-by-case analysis. Testing on self-provided samples is recommended before finalizing values.
Three Common Mistakes
- Phenomenon: A
504 Gateway Timeouterror appears during docker-compose deployment. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, leading to timeout when parsing large-volume industrial metal data. - Phenomenon: Custom prompts and reference templates cannot be used in the open-source version V4.8.22. Cause: This version does not expose the advanced configuration module. Upgrade to V4.9.0 or a later version.
- Phenomenon: Chunk index content cannot be obtained when calling the API. Cause: The chunk storage configuration of the vector database is not enabled, or the
Chunk sizesetting exceeds the maximum chunk limit supported by the database.
How to Verify Correct Configuration
- Check the scheduled task log to confirm that the market data pull interval matches the configured
CRONexpression. - Upload an industrial metal industry weekly report to verify that parsed fields match the preset mapping rules.
- Initiate a marketing content generation test to confirm that the number of recalled documents aligns with the configured
Recall countparameter. - View the vector database monitoring panel to confirm that the single batch imported data volume does not exceed the configured sharding threshold.
