What the data for this category looks like
Daily report data related to water utility yield rate mainly comes from public operational reporting data of local municipal water utility authorities, and daily collection data from third-party water industry monitoring institutions. The data update cadence is once per day, and the aggregation and release of the day's operational data is usually completed by the early morning of the next day. Most documents are in structured CSV or JSON format. Each row corresponds to the day's water operation information for a single administrative region. Included fields are administrative region code, total daily water supply, total daily water sold, total daily water supply cost, daily sewage treatment volume, daily sewage treatment service revenue, and daily pipe network maintenance expenses. Each field corresponds to different physical units such as ten thousand cubic meters, ten thousand yuan, ten thousand tons, etc.
What constraints do these characteristics impose on the "model access and configuration" link
The above characteristics of water utility data impose clear constraints on the model access and configuration link. Multi-region decentralized data sources require configuration of multi-source data adaptation rules. Field names and formats vary across different regions, so unified mapping to a standard template is required. The daily update cadence requires configuration of a matching timed sync interval to avoid triggering pull tasks too early or too late, ensuring that the latest day's data is obtained. The structured multi-field design requires configuration of field validation and unit alignment rules to prevent model input abnormalities caused by unit confusion or missing fields. Batch multi-field data requires configuration of appropriate context window parameters to adapt to the model's input length limit, avoiding data truncation that affects analysis results.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
dataset_sync_interval | 86400 seconds | Matches the daily update cadence of water utility daily reports, ensures one pull of latest data per day |
field_mapping_rule | Map regional data source standard field names to a unified template | Compatibility with differences in field naming across regional water utility data, enables unified access to multi-source data |
data_parse_timeout | 300 seconds | Structured water utility data includes multiple regions and fields, requires sufficient time to complete format validation and field alignment |
max_context_length | 8000–12000 characters | Single-region water utility daily report data is approximately 1000 characters, requires adaptation to model input limits for multi-region batch processing |
error_field_policy | Retain original fields and mark anomalies | Abnormal values in water utility data may reflect regional operational anomalies, retain original data for subsequent analysis |
api_request_rate_limit | 10 requests per minute | Complies with access rate limits of most public water utility data sources, avoids triggering access bans |
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.
Three common errors
- Phenomenon: An error
Cannot read properties of null (reading 'q')is thrown when calling the model. Cause: No configuration for the mapping rule between data source fields and model input fields, resulting in missing required input fields in the model's request body. - Phenomenon: No new data updates after a timed sync task runs. Cause:
dataset_sync_intervalis set to a cadence that does not match the water utility daily report update rhythm, so synchronization is not triggered after daily data is produced. - Phenomenon: Key fields are missing from parsed water utility data. Cause: The abnormal field retention policy of
error_field_policyis not enabled, and missing operational data fields are directly filtered out, resulting in incomplete model input.
How to confirm the configuration is complete
- Manually trigger a data sync task, check whether the latest water utility daily report data file appears in the dataset management page.
- Call the model test interface, pass simulated single-region water utility daily report data, check whether the returned results include analysis content corresponding to the operational data.
- View the system task log, confirm that the execution time of the timed sync task matches the daily production time of the water utility daily report.
- Check the field mapping configuration page, confirm that all accessed data source fields have been correctly mapped to the unified template.
