What the data for this category looks like
The data for industrial park financing daily reports mainly comes from exports of park operation management systems, summaries of financing reports from settled enterprises, and docking ledgers submitted by cooperating financial institutions. Updates occur daily. Each daily report covers enterprise financing updates in the park for the current day or the last three business days. Most documents are in PDF or CSV format, with fixed header fields: park entity name, full name of settled enterprise, financing docking institution, financing amount (unit: ten thousand yuan), financing arrival date, financing purpose. Some documents include an overall park financing summary row, with statistics such as total daily financing amount and number of settled enterprises.
What constraints do these characteristics impose on the "document parsing and chunking" link
Multiple format sources require the parsing module to support both structured CSV and formatted PDF parsing. It must accurately identify the correspondence between headers and data rows to avoid field misalignment. High-frequency daily updates require setting reasonable timeouts for parsing tasks, to prevent task queue blocking from overly long single-document parsing. Fixed fields with format differences require retaining the binding relationship between fields and values during chunking, to prevent loss of associated information after splitting. For documents with summary rows, the summary row must be bound to the enterprise entries for the corresponding time period during chunking, to avoid separating statistical data from main entity data. Long table documents may be split across PDF pages, so cross-page table merging parsing must be enabled to ensure data integrity.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single industrial park financing daily report is usually 5-15 pages. Conventional parsing takes 120-180 seconds, so this sets a reasonable buffer |
maxChunkSize | 800–1000 characters | Daily report fields are mostly short text combined with numerical values. This length covers the complete content of a single enterprise financing entry plus notes, preventing loss of associated information |
CSV_IMPORT_COLUMNS_LIMIT | First 8 columns | The core fields of a standard park financing daily report do not exceed 6. Reserving 2 columns for non-required notes or contact information avoids importing irrelevant columns |
UPLOAD_FILE_MAX_SIZE | 50 MB | A single park financing daily report (including multi-day summaries) usually does not exceed 10 MB. This setting prevents invalid large files from occupying storage |
PARSE_TABLE_MERGE_ENABLE | Enabled | PDF reports may have tables split across pages. Enabling this configuration merges structurally identical cross-page tables to ensure data integrity |
CHUNK_OVERLAP_SIZE | 50–80 characters | Short text chunking requires retaining contextual association. This overlap length connects field information between adjacent chunks |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: After uploading a PDF-format financing daily report, the interface shows a parsing timeout and fails to return parsing results. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not configured correctly. The default timeout period is too short to cover the full parsing process of a single document. - Symptom: After importing a CSV-format financing daily report, only the first two columns of data are read normally, and subsequent column fields are empty. Cause: The
CSV_IMPORT_COLUMNS_LIMITparameter is not adjusted. The default configuration only allows importing the first two columns, which does not adapt to the multi-field structure of park daily reports. - Symptom: A 413 error is returned when uploading a file in a Docker deployment environment. Cause: The upload size limit configuration for the Docker container is not modified, or the FastGPT
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, causing the file upload size to exceed the container limit.
How to confirm the configuration is correct
- Upload a standard-format industrial park financing daily report, check the time-consuming logs of the parsing task, and verify that the timeout configuration covers the actual parsing time.
- Import a CSV-format daily report file, check that all preset fields are included in the parsed data columns, and confirm that the column limit configuration matches the document structure.
- Upload a test file larger than the conventional volume, verify that the upload and parsing processes work normally, and confirm that the upload size configuration matches the actual file size.
- View the chunked text content, confirm that table data is not split, and that adjacent chunks retain field associations, to verify the effect of the table merging and chunk overlap configurations.
