What Data for This Category Looks Like
Industrial metal data sources primarily include public market data from major global commodity exchanges, inventory and import-export data released by industry associations, and shipment announcements from upstream mines and smelters. Update frequencies vary: spot market data updates in real time intraday, inventory data updates weekly, and industry analysis reports update monthly. Most documents are structured tables with fields including product, statistical date, price, total inventory, import-export volume, and more. Common units are USD/ton, CNY/ton, and ten thousand tons. Some overseas data sources use GBP/ton as the price unit, which requires additional adaptation and conversion.
How These Characteristics Create Constraints for Workflow Orchestration
The varied update rhythms of industrial metal data require splitting the workflow into separate pull nodes for each data source, aligned to their respective update cycles. Structured data with inconsistent units and field differences requires adding standardized processing nodes to unify field names and measurement units. Third-party data source authentication and call frequency limits require configuring current-limiting and authentication nodes in the workflow to avoid triggering risk control intercepts. Differences in response speeds across data sources require setting differentiated timeout thresholds for individual nodes to prevent overall workflow interruption. Due diligence reports require integrating multi-dimensional data, so the workflow needs a data aggregation node to combine scattered market, inventory, and import-export data into a unified output format.
How to Set the Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
trigger_type | Split by data source with scheduled triggers | Industrial metal data has highly varied update rhythms, requiring alignment with each data source’s update cycle |
api_rate_limit | 10 requests per minute | Most industrial metal market data APIs have call frequency limits to avoid triggering risk control |
field_mapping_rule | Unify units to CNY/ton and ten thousand tons | Units vary across different data sources, requiring standardized field formatting |
timeout_threshold | 30 seconds for market data nodes, 60 seconds for inventory data nodes | Differences in response speeds across data sources prevent workflow interruptions from timeouts |
global_var_scope | Visible across the entire workflow | Core data such as market and inventory needs to be passed between multiple nodes |
request_header_config | Include API_KEY and Referer | Authentication requirements for most third-party industrial metal data sources |
The parameter values provided on this page are common recommended 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 your own samples before finalizing settings.
Three Common Errors
- Phenomenon: The published workflow runs with old logic, and output results do not meet expectations. Cause: The associated release channel configuration was not updated synchronously after modifying the workflow, so the release channel remains bound to the old workflow version.
- Phenomenon: The workflow throws a
400 Bad Requesterror with the promptglobal variable not found. Cause: Global variables were not declared in advance in the workflow initialization node, or the variable scope was configured as node-only, making it unreadable by subsequent nodes. - Phenomenon: The workflow sends a third-party API request and returns empty data, and field verification fails. Cause: The request header was not configured with correct authentication parameters, or the global variable was not correctly bound as the API_KEY in the request node, leading to authentication failure.
How to Confirm Proper Configuration
- Trigger the pull node for the corresponding data source, and verify that the returned data fields and units conform to the preset standardized rules.
- View workflow logs to confirm that global variables are passed normally between nodes, with no missing or formatting errors.
- After simulating a workflow modification, check whether the associated release channel has updated its configuration synchronously, or manually trigger the release channel update to validate execution logic.
- Call the third-party API node, confirm that the returned status code is 200, and that the data format matches the preset field requirements.
