What This Category of Data Looks Like
Solid waste treatment research report data mainly comes from officially published documents of ecological environment departments, annual reports of industry associations, and special research documents from third-party monitoring institutions. Update cycles follow three patterns: policy documents are updated immediately upon release, industry technical research reports are updated monthly, and project cases are updated synchronously upon implementation. Document structure includes fields such as policy clauses, disposal process parameters, emission limits, and disposal cost accounting. Most quantitative indicators use units including tons/year, mg/L, ten thousand yuan/ton, and similar units.
How These Data Characteristics Impact Workflow Orchestration
The multi-source and dispersed nature of solid waste treatment research reports requires the workflow to include multiple data source pull nodes. These nodes must connect separately to official platforms, industry association interfaces, and local document libraries. The varying update cycles for different report types require the workflow to support both scheduled triggering and event triggering modes. Inconsistent field units require the workflow to have a field standardization mapping node to unify units such as tons/year and mg/L. Highly time-sensitive policy content requires the workflow to include an update verification step to filter expired policy content. A high proportion of long documents requires the workflow to include a segment splitting node to adapt to the context limits of retrieval models.
Configuration Settings
| Configuration Item | Recommended Value | Basis for This Value |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Solid waste treatment research reports often contain long texts and structured tables. The default 60-second timeout is insufficient for complete parsing. |
maxContext | 8000–12000 characters | The length of a single solid waste treatment research report mostly falls between 5000 and 10000 characters. This range adapts to the context windows of mainstream large models. |
Recall count | Top 8 entries | Solid waste treatment research reports are dense with professional terminology. Too many retrieved entries will cause context overload. |
Similarity threshold | 0.75–0.85 | Filter low-match invalid research reports and avoid irrelevant content interfering with retrieval. |
ENV_VAR_ENABLE | Enabled | Required when calling custom environment variables passed during Docker deployment, such as API keys for solid waste disposal cost accounting. |
SQL_RETRY_COUNT | 2 retries | Retries can improve query success rates when database queries face network fluctuations or interface rate limiting. |
The parameter values provided on this page are conventional starting point recommendations. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing configuration.
Three Common Configuration Mistakes
- A null value is returned after the workflow calls an environment variable. The symptom is that the node output field is empty. The cause is that in the open-source version 4.8.17,
ENV_VAR_ENABLEis disabled by default, or custom environment variables are not passed correctly during Docker deployment. - The result of index increment 1 in the loop body is null. The symptom is abnormal output of the loop node. The cause is that the initial index of the loop body is not set to 0, or the step size configuration exceeds the loop range.
- The database query workflow reports an error and returns no data. The symptom is that the node returns SQL execution failure or empty results. The cause is that the field names of solid waste treatment research reports are not mapped to database table fields, or the SQL statement does not specify correct filtering conditions.
How to Verify Successful Configuration
- Enter the workflow test page, upload a single solid waste treatment research report document, trigger the parsing node, and check whether the parsing result contains complete policy clauses and technical parameters.
- Run the workflow to retrieve research reports related to solid waste disposal, and verify whether the number of returned results and similarity threshold match the configured values.
- Call the environment variable node, and check whether the node output contains the custom parameters passed during Docker deployment.
- Run the database query node, and verify whether the field units of the returned data have been standardized to preset formats such as tons/year and mg/L.
