What the Data for This Category Looks Like
Public utility gas price monitoring platforms and official disclosed data from regional gas supply companies are the primary data sources. Updates occur once daily. Market data for the previous calendar day is released by 10:00 AM on the current day. Document formats are mostly structured table files or standardized JSON API responses. Fields include gas supply category, current day transaction unit price, previous cycle transaction unit price, region identifier, data release date. The unit for transaction unit price is yuan/cubic meter.
How These Data Characteristics Impact Workflow Orchestration
The daily fixed-update data source requires a scheduled trigger node in the workflow. The trigger time must be later than the data release time to avoid pulling ungenerated same-day data. Gas data across multiple regions and categories has inconsistent field naming. A field mapping step must be configured to unify data formats. Yield rate calculations rely on current day and previous cycle unit price data. The data pull time window must be limited to two consecutive days to exclude expired or redundant data. Some regions may have no transactions on the current day. A null value branch processing logic must be configured to prevent workflow interruptions. Public monitoring platforms have call frequency limits. A reasonable request interval and retry mechanism must be implemented.
Recommended Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Scheduled Trigger Cycle | Once daily, fixed trigger time at 10:30 AM | Matches the gas daily report release cadence, ensures complete previous calendar day data is pulled |
Data Pull Time Offset | Trigger 10 minutes early | Reserves buffer time for data synchronization, avoids pulling empty data due to platform delays |
Field Mapping Rules | Map according to "category/region/current day unit price/comparison unit price/release date" | Unifies field differences across multiple data sources, adapts to the fixed field requirements for yield rate calculations |
Time Window Range | Two consecutive natural days | Limits the data pull time range, only retrieves the current day and previous day data required for calculations |
Request Retry Count | 2 retries, 60-second retry interval | Addresses temporary call restrictions on public platforms, reduces workflow failure probability |
Null Value Handling Branch | Skip calculation for the current category/region, record logs | Prevents workflow interruptions due to missing transaction data, retains basis for exception troubleshooting |
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 Configuration Mistakes
- Phenomenon: The text content extraction component returns empty results. Normal extraction only resumes after re-adding the component with the same configuration. Cause: The component caches previously failed context configurations and fails to correctly load the latest data source field mapping rules.
- Phenomenon: The text content extraction component cannot retrieve gas data fields during some large model calls. Normal functionality resumes after switching large models. Cause: Different large models have differences in context window size and instruction following capability. Small parameter models cannot accurately match structured data extraction rules.
- Phenomenon: When calling a chat model in the workflow, the market query parameters entered by the user cannot be retrieved. Cause: The system preset user question variable name was not used correctly, leading to parameter binding failure.
How to Verify Proper Configuration
- Manually trigger the workflow once. Check if the pulled gas data includes preset fields, and verify that the field mapping matches the configured settings.
- Simulate a scenario with no transaction data. Check if the workflow triggers the null value handling branch and generates corresponding logs.
- Switch between different large models to verify that the text extraction component can stably retrieve gas data fields.
- Check the scheduled trigger run logs to confirm that data is successfully pulled at the fixed daily time, with no duplicates or omissions.
