What the data for this category looks like
Plastics and rubber research report data comes from domestic industry associations, bulk commodity spot trading platforms, and professional research report institutions. Updates follow three schedules:
- Spot price data updates daily
- Industry supply and demand benchmark data updates weekly
- Specialized research reports for segmented product categories release irregularly alongside industry developments
Document structures include product segment entries, supply and demand benchmark data, price ranges, downstream application fields, policy summaries, and other modules. All fields use standard industry units, with no custom non-standard units.
Constraints on HTTP interfaces and external systems
Differences in data update frequencies require interfaces to support filtering data sources across time ranges. This prevents returning outdated or duplicate data.
There are many product segment entries, so interface query parameters must support precise matching of product names or codes. This stops retrieval results from mixing content from other categories.
Individual research report documents have long text lengths. Interfaces must support long text parsing and context transfer, while also supporting batch retrieval of multiple product categories to reduce call counts.
Specialized research reports release irregularly. Interfaces must support incremental pulling of newly published content. This improves data synchronization timeliness for external systems.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 10-20 entries | Plastics and rubber research reports have long individual content. Too many recalled entries exceed context limits, while too few result in insufficient coverage |
Similarity threshold | 0.75-0.85 | Research report content has high professionality. A higher threshold filters irrelevant results and prevents mixing data from other categories |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Individual plastics and rubber research report documents have long text lengths. The default parsing timeout duration is insufficient for complete parsing |
Batch Query Upper Limit | 5 product categories | Too many requests in a single batch cause interface response timeouts. Limiting the number of product categories ensures call stability |
Global Variable Pass-through Switch | Enabled | External system calls require passing business identification parameters. Enabling this allows parameter pass-through |
Interface Retry Count | 2 retries | Bulk commodity data interfaces occasionally experience fluctuations. Limited retries reduce call failure rates |
This page provides parameter values as common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing values.
Three Common Misconfigurations
- Calling the interface returns the "Cannot read properties of undefined" error. This occurs because the global variable pass-through switch is not enabled, so business parameters passed externally cannot be properly received by the interface.
- Interface retrieval results mix content from other categories such as steel, chemical fiber, etc. This occurs because precise category matching parameters are not configured, and only fuzzy keyword retrieval is used without limiting category fields.
- Interface calls return a 504 timeout status code. This occurs because the
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted; the default timeout duration cannot cover the parsing process for long document research reports.
How to Verify Proper Configuration
- Call the interface with specified plastics and rubber product category parameters. Check that returned results only include research reports and data for the corresponding category, with no content from other categories.
- Review interface call logs. Confirm that globally variable parameters passed externally are correctly parsed and loaded into the conversation context.
- Call the interface 10 times consecutively with no timeouts or errors. Confirm that the retry mechanism and timeout parameter configurations are active.
- Adjust the
Similarity thresholdparameter to 0.9. Check that the relevance of returned results improves, confirming that the threshold configuration is active.
