What This Category of Data Looks Like
Publishing research report data mainly comes from official research report libraries of professional publishing institutions. The update rhythm matches the research report release cycle, and new industry and individual stock research reports are usually updated daily. The structure of a single document includes modules such as cover page, table of contents, core analysis data, industry trends, and rating conclusions. Fields include unique report identifier, publishing institution, publish time, affiliated industry, investment rating, target price, total word count, etc. Target price is measured in RMB yuan, and total word count is counted in thousands of characters.
Constraints Imposed on HTTP Interfaces and External Systems by These Characteristics
Long research report documents with structured fields require interfaces to support longer request timeouts and custom return field configurations. High update frequency and large total data volume require interfaces to support incremental pulling by publish timestamp and paginated retrieval, to avoid interface overload caused by full pulling. The existence of structured fields such as target price and investment rating requires interfaces to support precise filtering retrieval by fields, and reserve field mapping configurations to adapt to naming differences of research report fields across different publishing institutions.
How to Set Configurations
| Configuration Item | Recommended Value | Basis for This Setting |
|---|---|---|
requestTimeout | 600–900 seconds | Long processing time required for single research report parsing and retrieval, to avoid task interruption due to timeout |
retrieveTopK | Top 10–20 entries | Large total volume of publishing research reports, limiting initial recall quantity reduces interface transmission load and processing pressure |
customReturnFields | Includes publishTime, rating, targetPrice, wordCount | Core retrieval needs for publishing research reports focus on fields like publish time, rating, target price, etc. Returning only specified fields reduces redundant data |
syncInterval | Every 15–60 minutes | Matches the daily release rhythm of research reports, avoids missing new reports if pulling interval is too long, or duplicate requests if interval is too short |
fileParseMaxSize | 20000–50000 thousands of characters | Single publishing research report document is usually long, need to relax size limits for file parsing |
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 your own samples before finalizing.
Three Common Misconfigurations
- Phenomenon: The interface returns a
413 Request Entity Too Largeerror. Cause: ThefileParseMaxSizeconfiguration is not adjusted, and the single research report file exceeds the default limit. - Phenomenon: Infinite restart errors occur on the deployed interface, and logs show
token encoder initialization failed. Cause: TherequestTimeoutparameter is not configured correctly, triggering a timeout reconnection cycle during long document parsing. - Phenomenon: The number of retrieval results does not match expectations, returning too many entries or containing redundant fields. Cause: The
retrieveTopKandcustomReturnFieldsparameters are not set correctly, resulting in the interface returning more data than required.
How to Confirm Configuration Is Correct
- A standard publishing research report file is uploaded, the parsing interface is invoked, the return status code is checked to be
200 OK, and parsing time is verified to not exceed the setrequestTimeoutvalue. - The retrieval interface is invoked, the
customReturnFieldsparameter is passed to specify required fields, and the returned results are checked to only include preset fields with no redundant content. - Incremental pulling of research reports by the latest publish timestamp is simulated, and the returned data is checked to have no duplicates and include the test latest research report.
- A research report file exceeding the default size is passed when invoking the interface, and the interface is checked to return parsing results normally without a
413error.
