What this category of data looks like
Data for this category comes from special equipment safety supervision systems, inspection and testing institution systems, user account books, and operator certificate databases. Daily documents include use registration certificates, periodic inspection reports, maintenance records, hidden danger rectification notices, accident reports, and operator certificates. The data update frequency is monthly. Most document structures are structured tables and standardized fixed-format documents. Fields include equipment numbers, inspection cycles, maintenance units, operator qualification numbers, and other items. There is no unified unstructured text format.
What constraints do these characteristics impose on the document parsing and chunking link
Since documents include structured tables, standardized documents, and scattered account books, the parsing process must support structured extraction of multi-format content and avoid splitting associated fields within tables. The monthly update frequency requires chunking logic to stay stable, preventing inconsistent retrieval matching between historical and new data caused by configuration changes. The integrity of core fields such as equipment numbers and inspection cycles directly impacts supervision operations. Chunking must retain contextual association of fields to prevent key information from being truncated. Document formats vary significantly across different sources, so flexible chunking rules must be configured to adapt to different document structures.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | This category of documents includes short fields such as equipment numbers and inspection cycles, as well as long-text rectification instructions. This range balances field association and retrieval granularity. |
chunkSplitter | Split by paragraph + table | Adapts to the paragraph structure of standardized documents and the integrity of structured tables, avoiding splitting associated data within tables. |
customPdfParse | Enabled | Most documents in this category are official standardized PDFs. Enabling this option preserves original layout and table structure, improving parsing accuracy. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Documents such as special equipment inspection reports may contain large numbers of images and attachments. This upper limit covers file requirements for most business scenarios. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large-volume inspection reports take a long time to parse. This duration prevents parsing failures caused by timeouts. |
chunkSettingMode | Manual configuration | Chunking rules must be adjusted for different types of special equipment documents. Manual configuration allows flexible adaptation to business needs. |
Three Common Misconfigurations
- Symptom: The parsing node does not respond after a file is uploaded, and the log reports
slow operation xxxxms. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. Parsing large-volume inspection reports exceeds the default threshold, triggering the timeout limit. - Symptom: Only partial data is captured in database tables, with missing fields. Cause:
customPdfParseis not enabled, orchunkSplitteris configured incorrectly. Structured tables are incorrectly split, resulting in lost associated fields. - Symptom: Content is truncated when the model outputs a Markdown table. Cause: The
chunkSizevalue is too small. The chunk containing the table is truncated early, failing to retain the complete table content.
How to Verify Correct Configuration
- Upload a single typical document, such as a periodic inspection report, and check if the parsed text retains complete table structure and field association.
- Review system logs to confirm there are no
slow operationtimeout errors, verifying that thePARSE_FILE_TIMEOUT_SECONDSconfiguration takes effect. - Randomly sample chunked content, and confirm that core fields such as equipment numbers and inspection cycles appear fully within the same chunk of text.
- Upload the largest-volume business file, confirm that the upload and parsing processes complete normally, verifying that the
UPLOAD_FILE_MAX_SIZEconfiguration covers requirements.
