What This Category of Data Looks Like
Chemical fiber research report data mainly comes from public statistics released by the China Chemical Fiber Industry Association, regular operational reports disclosed by leading chemical fiber enterprises, commodity market databases, and segmented category reports from professional consulting firms. Updates occur daily on workdays. Temporary reports are added when sudden raw material price fluctuations or industry policy adjustments take place. Single document lengths vary widely. It is recommended to conduct statistics or testing based on samples before making decisions. Core fields include raw material unit price (unit: yuan/ton), capacity utilization rate (unit: percentage), downstream order volume (unit: 10,000 meters), and monthly import and export data (unit: 10,000 tons). The structure includes modules such as industry overview, supply and demand balance, price trends, and risk warnings.
What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems
High-frequency updates, structured fields with units, and long documents of chemical fiber research reports impose multiple constraints on HTTP interfaces and external systems. Daily fixed industry data updates require interfaces to adapt request frequencies to industry release windows, avoiding data lag caused by request congestion. Core fields with clear units require interface return fields to strictly retain preset units, with no automatic conversion. Otherwise, external system parsing errors will occur. The existence of long single documents requires interfaces to support paged returns or segmented pulling, preventing timeout limits from being triggered when too much data is returned at once. Irregularly released temporary reports require external systems to configure incremental pulling mechanisms to obtain the latest content in a timely manner.
Configuration Settings
| Configuration Item | Suggested Value | Basis for This Selection |
|---|---|---|
REQUEST_RATE_LIMIT | 10 requests per minute | Adapts to the daily fixed batch release rhythm of chemical fiber research reports, avoiding triggering interface rate limiting |
PULL_MODE | Incremental Pull | Adapts to the irregular release of temporary reports, reducing resource consumption from invalid full pulls |
PRESERVE_FIELD_UNIT | Enabled | Strictly matches preset units of chemical fiber research report fields, avoiding external system parsing errors |
PAGE_SIZE | 10 items per page | Controls the number of research reports returned in a single interface request, adapting to the batch processing capabilities of external systems |
API_TIMEOUT | 30 seconds | Addresses time consumption requirements for long document parsing and bulk data pulling, avoiding early timeout triggers |
MAX_RESPONSE_SIZE | 1500 KB | Limits the total data volume returned in a single request, preventing external system memory overflow |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on samples before finalizing decisions.
Three Common Misconfigurations
- The interface returns an error message indicating token encoder initialization failure, with the process restarting infinitely. The cause is that a reasonable
maxContextparameter is not set. Text splitting for long documents exceeds the model's token limit, triggering underlying interface encoding errors. - The interface returns error status code 429, indicating request frequency exceeded. The cause is that the
REQUEST_RATE_LIMITconfiguration value is higher than the actual rhythm of industry data release, triggering high-frequency requests to be blocked. - Pulled research report fields lack unit information. The cause is that the
PRESERVE_FIELD_UNITconfiguration is not enabled. The interface automatically clears unit identifiers from original fields, causing external systems to fail to parse data correctly.
How to Confirm Configuration is Correct
- Send a single batch pull request, check if returned fields include preset unit information to confirm the configuration is active.
- Send 15 consecutive requests, observe interface return status codes to confirm request frequency does not trigger rate limiting.
- Pull a single long-form research report, check if returned results are paginated according to
PAGE_SIZEto confirm pagination configuration is correct. - Check interface logs, confirm that pull requests are only triggered when new research reports are published to confirm the incremental pull configuration is active.
