What Data for This Category Looks Like
Daily yield and market data for energy metals is sourced from domestic commodity exchanges, international metal trading markets, and third-party compliant data service providers. Data is divided into two categories: real-time quotes and daily statistics. Daily statistics data updates after each trading day closes. Individual data entries use a structured format, including fields such as product code, trading market identifier, daily benchmark price, daily price fluctuation range, position size, total trading volume, and more. Price fields use units of yuan/ton or USD/ton. Position and trading volume fields use units of lots or tons. Field names vary slightly across different data sources.
Constraints Imposed by These Characteristics on Model Integration and Configuration
Multi-source data access requires adapting to authentication methods and interface specifications of different trading markets, increasing configuration complexity. Daily and real-time data have different update frequencies. Model trigger timing must be differentiated to match broadcast requirements. Large differences exist in field naming across data sources. Unified field mapping rules must be configured to ensure data alignment. Long data documents with many fields require limiting recall scope to avoid overloading model processing. Cross-market data pulling takes a long time. Sufficient timeout periods must be reserved to ensure task completion.
How to Set Configurations
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
RETRIEVE_TOP_K | Top 10-15 entries | The energy metals category has many data fields. Core fields must be retained after filtering redundant information. Excessive recall increases model processing load |
RERANKER_TRIGGER_LENGTH | 800-1200 characters | Single energy metals data documents are relatively long. Reranking triggers when the threshold is exceeded to improve sorting accuracy |
DATA_FETCH_TIMEOUT | 600 seconds | Multi-source data pulling covers domestic and international market interfaces, which takes a long time. Sufficient timeout periods must be reserved |
FIELD_MAPPING_RULE | Preset mapping templates by market | Large differences exist in field naming across different trading markets. Preset templates reduce manual configuration costs |
RERANKER_MODEL | Qwen3-Reranker-8B | Adapts to long-text sorting requirements, supports multi-field associated sorting for energy metals data |
ERROR_RETRY_TIMES | 2-3 times | Commodity trading interfaces may experience occasional fluctuations. Retries reduce the probability of failed data pulls |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material forms, data volume and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: High latency occurs after model invocation. Cause: No batched data pulling strategy is configured. Pulling all energy metals category data in a single request causes interface request overload.
- Phenomenon: Reranker model passes deployment tests, but retrieval results return
falseafter reranking. Cause: Authentication parameters forRERANKER_MODELare not configured correctly, or model path configuration errors cause loading exceptions. - Phenomenon: Reranker model is not invoked after knowledge base retrieval content is too long. Cause: The
RERANKER_TRIGGER_LENGTHparameter value is greater than the actual length of the retrieved text, so the reranking logic does not trigger.
How to Confirm Configuration Is Complete
- View data pulling logs to confirm that data sources from different trading markets complete synchronization within the preset time window. Check that field names after mapping match expected values.
- Simulate triggering a daily report broadcast task, view model invocation logs to confirm that the reranker model is properly loaded and executes sorting logic without error messages.
- Adjust the retrieved text length to verify that the reranking logic triggers normally when the text length reaches the preset threshold, and returns sorted results.
- Test exception scenarios where interfaces are temporarily unavailable, confirm that the retry mechanism triggers normally and completes data pulling after retries.
