What the data for this category looks like
Core data sources for solid waste treatment yield rates include three categories: project operation ledgers, daily market quotes for recycled products, and environmental protection regulatory subsidy ledgers. Data is compiled for the previous day every early morning. Only current day and last 7 days of historical data can be queried. Data uses structured key-value pair format, with fields including project code, disposal category, daily total disposal volume, unit disposal cost, recycled product unit price, daily subsidy amount, unit net revenue, and others. Units: total disposal volume is measured in tons, cost and unit price in yuan/ton or yuan/kilogram, and unit net revenue in yuan/ton.
What constraints these characteristics impose on workflow orchestration
First, multi-data source pull order must strictly match the data update schedule. Pull operation ledgers and subsidy data first, then market quotes. This avoids calculation deviations caused by unready data. Second, field differences must be unified via mapping rules. Project field names vary by disposal category. Preset mapping logic to align fields, ensuring consistent input for subsequent calculations. Third, scheduled triggers must adapt to the data update cycle. Set the trigger to run after early daily hours, ensuring complete previous day's data is available for pulling. Fourth, limit concurrent count for multi-node parallel pulls. This prevents triggering API rate limits when requesting multiple data sources simultaneously, which harms workflow stability.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Scheduled Trigger Cycle | Daily 02:00 | Most associated data sources complete daily data compilation before 1 AM. This time ensures complete previous day's data is available for pulling |
HTTP Request Retry Count | 3 times | Some environmental regulatory platforms and market quote interfaces have temporary rate limits. Retries reduce the impact of single request failures |
Timeout Period | 600 seconds | Covers total time for multi-node data pulling, field mapping, and yield rate calculation, preventing mid-run interruptions |
Field Mapping Rules | Preset mapping table by disposal category | Field names for costs and recycled products vary by solid waste disposal type. Preset mappings unify input fields for subsequent calculations |
Concurrent Request Limit | 5 | Restricts the number of simultaneous HTTP requests, avoiding triggering rate limit rules from third-party interfaces |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: Workflow outputs empty fields. Cause: Field mapping rules are not configured. Field names from different data sources are not unified, so subsequent calculation nodes cannot read valid data.
- Symptom: Workflow triggers return
504 Gateway Timeouterrors. Cause: TheTimeout Periodparameter is not adjusted. Total time of multi-node HTTP requests exceeds the default threshold, and no retry mechanism is configured. - Symptom: Workflow data cannot be shared in a multi-node deployment environment. Cause: Shared storage mounting is not configured correctly, or corresponding environment variables are not added to the compose file. Nodes cannot access unified runtime data.
How to confirm proper configuration
- View workflow run logs, check the return status codes of each HTTP request node to confirm pulling operations succeeded.
- Manually trigger the workflow once, compare output result fields with preset mapping rules to confirm correct field matching.
- Verify the scheduled trigger configuration, observe whether the workflow starts automatically per the preset cycle.
- In a multi-node deployment environment, check if all nodes can access unified workflow runtime data to confirm shared configurations are active.
