What Data for This Category Looks Like
The typical users of this category are architects, technical leads, and platform development teams. Daily produced documents include technical solutions, architecture topology diagrams, capacity assessment reports, and technical review minutes. Data sources are mostly historical business traffic, service deployment topologies, cluster monitoring metrics, and medium- and long-term business growth plans. Document update frequency is usually once per month or alongside major business requirement changes. Document structures typically include modules such as constraints, solution demonstrations, dependency relationships, and review comments. Fields mostly involve resource usage, response latency, service boundaries, etc., with units including CPU cores, storage capacity, time cycles, etc.
Constraints Imposed on Document Parsing and Chunking by These Characteristics
The structured nature of daily documents requires that chunking must not destroy chapter logic and dependency relationships, otherwise subsequent retrieval will fail to match complete solution demonstration content. Document sources include monitoring metrics and topology data, which contain a large number of technical abbreviations and proprietary terms. Chunking must retain contextual associations to ensure retrieval accuracy. Uncertain update frequencies require the parsing process to support both incremental update and full re-parsing modes, to avoid repeated parsing of full documents. Document volume varies widely, ranging from a few pages of review minutes to dozens of pages of capacity assessment reports. Chunking configurations must adapt to parsing needs for documents of different sizes.
How to Configure Settings
The following configurations are based on FastGPT v4.17.0:
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Architecture design documents mostly contain structured paragraphs and technical parameters. This length can retain the complete semantics of a single constraint or solution demonstration |
chunkSplitter | Split by Markdown headings/paragraphs | Daily documents are mostly in Markdown format or exported structured documents. Splitting by headings can retain chapter integrity and hierarchical relationships |
customPdfParse | Enabled | Architecture diagrams and review minutes are often uploaded in PDF format. Enabling this option retains text hierarchy and embedded chart description text |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large documents containing multiple architecture diagrams and monitoring data take longer to parse. This duration prevents parsing tasks from timing out mid-execution |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Archived architecture documents may contain multiple attachments and topology diagrams. This upper limit covers document volume requirements for most business scenarios |
Three Common Misconfigurations
- Symptom: After uploading a Word or Excel document, no matching results appear in knowledge base searches, and the interface displays a parsing error. Cause: The
customPdfParseconfiguration is not enabled, or correct chunking rules are not configured for Office documents, resulting in incorrect text truncation or loss of key information. - Symptom: Knowledge base search tests return an unexpected number of results, only returning scattered partial content. Cause: The
chunkSizevalue is too small, causing complete constraints or solution demonstrations to be split across multiple chunks, preventing retrieval of complete semantics. - Symptom: After updating the version, the original miner-u-related parsing function entry cannot be found. Cause:
chunkSettingModeis not switched to custom mode, or the corresponding parsing plugin is not enabled. The original miner-u function has been integrated into core configuration items.
How to Verify Successful Configuration
- Upload a typical architecture solution document, view the parsed chunk preview, and confirm that each chunk contains a complete chapter or demonstration paragraph.
- Run a knowledge base search test, enter keywords containing constraints or service dependencies, and confirm that the returned results include complete fragments of the corresponding document.
- Upload an archived document with a volume not exceeding 1000 MB, and confirm that the parsing task completes within 600 seconds with no timeout errors.
- Check the switch status of the
customPdfParseconfiguration item, and confirm that PDF format architecture diagram documents retain text hierarchy and embedded chart descriptions after parsing.
