What the data for this category looks like
Minor metals industry data primarily comes from monthly briefings from domestic nonferrous metal industry associations, real-time quotes from professional spot trading platforms, and public production and sales announcements from mining and smelting enterprises. Data update cadences fall into three categories: spot quotes are updated daily, inventory and production and sales data are updated weekly, and industry analysis reports are updated monthly. A single data document typically includes fields such as variety identifier, daily spot average price, regional ex-factory price, monthly cumulative production volume, import and export volume, inventory turnover days, and more. Units cover yuan/ton, kilogram, cubic meter, and some sub-categories will include raw material purity parameters.
What constraints do these characteristics impose on workflow orchestration
The layered update cadence of minor metals data requires workflow configurations to include multiple scheduled trigger nodes, each adapted to daily, weekly, and monthly data pull tasks. The diversity of fields and units requires data preprocessing nodes to add multiple sets of format validation rules, and perform conversion adaptation for different units such as yuan/ton and kilogram to avoid numerical calculation deviations. The significant differences in exclusive parameters between sub-categories require workflow branch nodes to support dynamically loading corresponding templates and parameters based on category to avoid adaptation errors in generic content. Some industry data sources have call frequency limits, requiring workflows to add current limiting and automatic retry configurations to prevent task interruptions caused by triggering call restrictions.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
workflow_cron_expression | 0 0 8 * * * (daily at 8:00), 0 0 0 * * 0 (Sunday 0:00) | Matches the official update times of minor metals spot quotes and inventory data |
data_format_check_rules | 3-5 rules | Minor metals data includes three core fields: spot price, inventory, and production and sales, so corresponding validation rules need to be configured |
api_request_rate_limit | 10 requests per minute | Complies with call frequency limits of most industry public data sources |
branch_condition_field | metal_category | Dynamically switches branch logic based on minor metal category |
llm_prompt_template | Calibrated based on actual testing | Marketing content focus varies significantly between different minor metal sub-categories |
workflow_retry_max_times | 3 times | Adapts to conventional retry needs for network fluctuations or temporary interface current limiting |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on applicable internal samples before finalizing settings.
Three common misconfigurations
- Phenomenon: After calling the
llm_chatnode in the workflow, downstream nodes cannot obtain the latest context data. Cause: The "new context" output of the node is not correctly connected to the input port of the downstream node, and only the "AI reply content" is used as the transferred data. - Phenomenon: A large number of 429 status codes or timeout errors occur when calling the workflow in batches. Cause: The
api_request_rate_limitparameter is not configured, or the value exceeds the call limit of the industry data source. - Phenomenon: After the workflow completes execution, the preset marketing content variables are not updated. Cause: The global effective scope is not configured in the variable update node, causing the variables to only take effect locally in the current node.
How to confirm the configuration is complete
- Manually trigger the workflow once, check the output logs of the data pull node to confirm that the pulled fields and units match the target data source.
- Switch between different minor metal categories to verify whether the branch node correctly loads the corresponding template, and check whether the generated marketing content matches the category characteristics.
- Call the workflow API and pass test parameters to check whether the returned results include correct variable values and generated content.
- View the workflow monitoring panel to confirm that scheduled trigger tasks execute at the preset times, with no frequent retries or error records.
