What this category of data looks like
Water utility financing daily report data is sourced from internal financing ledgers of local water utility groups, financing information for water projects published by regional financial regulatory authorities, and credit and loan vouchers from partner banks. The update frequency is daily. A single daily report document typically includes structured tables and unstructured explanatory text, with some including detailed attachments in CSV format. Document fields include project number, water utility project name, financing amount, financing subject, cooperating financial institution, loan date, repayment period, and guarantee method. The unit for all amounts is uniformly ten thousand yuan.
Constraints imposed on document parsing and chunking by these characteristics
Batch daily updated data sources require the parsing process to support batch scheduling to prevent single-file processing timeouts. Documents mixing structured tables and unstructured explanatory text require precise differentiation between table regions and associated main text to avoid splitting details and explanatory text for the same financing project apart during chunking. Documents with CSV detailed attachments require identifying attachment formats and parsing column data synchronously. The unified amount unit requires automatic alignment of field units during parsing to avoid inconsistent units after chunking. Single documents with large page spans require setting reasonable chunk boundaries to avoid splitting the same project information across pages into different chunks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | The average parsing time for a single water utility financing daily report document does not exceed 300 seconds, to avoid timeout backlogs in batch tasks |
UPLOAD_FILE_MAX_SIZE | 1000 MB | The total size of a single daily report document and its attached files typically does not exceed 500 MB, with reasonable buffer space reserved |
chunk_size | 800–1200 characters | Matches the length of project details and explanatory text in water utility financing daily reports, to avoid splitting apart associated information |
chunk_overlap | 100–150 characters | Retains associated overlap for project information across pages, ensuring complete project content can be retrieved |
ENABLE_ATTACHMENT_PARSE | Enabled | Some daily reports include CSV format detailed attachments, requiring synchronous parsing of structured data within attachments |
EMBEDDING_MODEL | BAAI/bge-large-zh-v1.5 | Adapts to semantic understanding requirements for water utility domain terminology, improving retrieval matching accuracy after chunking |
The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing.
Three Common Misconfigurations
- A 413 status code is returned when uploading a file for parsing. The cause is that the
UPLOAD_FILE_MAX_SIZEconfiguration value is smaller than the actual total uploaded file size, and the maximum request body limit for the Docker deployment environment was not adjusted synchronously. - Only the first two columns of data are extracted after parsing a CSV format attachment. The cause is that the full-column CSV parsing configuration was not enabled, or the parsing column range parameter was not specified correctly.
- Timeouts occur for custom parsing service requests, and the timeout configuration item cannot be located. The cause is that the configuration entry for
PARSE_FILE_TIMEOUT_SECONDSwas not found in system settings, or the timeout threshold was not configured in the custom service interface itself.
How to Verify Correct Configuration
- Upload a standard water utility financing daily report document, and check that the file size in the parsing log matches the range specified by the
UPLOAD_FILE_MAX_SIZEconfiguration. - Upload a daily report document with a CSV attachment, and confirm that the parsing result includes all column data from the attachment.
- Review the chunking results to confirm that the same financing project across pages was not split into different chunks, and that chunk lengths fall within the preset range.
- Trigger a batch parsing task, and confirm that all documents complete parsing within the time period specified by the
PARSE_FILE_TIMEOUT_SECONDSconfiguration.
