What data for this category looks like
Consumer building materials financing daily report data mainly comes from local building material industry association announcements, supply chain finance platform transaction ledgers, and regional dealer financing filing documents. Updates occur daily. The length of individual daily report documents varies widely. It is recommended to calculate or test based on available samples. Reports are divided into sections by building material subcategories, such as waterproof membranes, architectural ceramics, decorative coatings. Each section includes fields including financing project name, financing amount, financing subject, lending institution, implementation date, project city, and others. The amount unit is uniformly ten thousand yuan. The date format is YYYY-MM-DD.
What constraints these characteristics impose on document parsing and chunking
Daily batch-updated documents require the parsing process to support batch scheduling. This avoids single-file processing timeouts. The subcategory-based section structure requires accurate identification of section boundaries. This prevents incorrect merging or splitting of cross-category content. Multi-field associated project information requires chunking to retain context binding between fields. This avoids broken links between financing subjects and their corresponding financing amounts after chunking. Wide variation in document length requires dynamic adaptation of chunking rules. This prevents complete information of a single financing project from being split into different content chunks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_BATCH_SIZE | 5–10 documents per batch | Adapts to daily batch update volume of consumer building materials financing daily reports, avoids excessive node memory usage per batch |
maxChunkSize | 800–1200 characters | Adapts to information density of single daily reports, retains complete context association of financing projects to avoid split breaks |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing requirements for single 30-page daily report documents, avoids mid-process timeout interruptions |
chunkOverlap | 100–150 characters | Retains context overlap between chunks, ensures cross-section associated information is not lost |
ENABLE_SECTION_DETECTION | Enabled | Accurately identifies section boundaries divided by building material categories in daily reports, avoids mixed splitting of cross-category content |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to volume of batch-uploaded daily report collection files, allows complete upload of batch documents |
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 case-by-case analysis, and it is recommended to perform testing on relevant samples prior to finalization.
Three Common Mistakes
- Phenomenon: Service triggers OOM errors after starting PDF parsing, with memory usage continuing to rise. Cause: No reasonable
PARSE_BATCH_SIZEis set, processing too many consumer building materials financing daily reports in a single batch, exceeding the node memory capacity limit. - Phenomenon: In knowledge base chunking results, information from the same financing project is split into multiple unrelated content chunks. Cause:
maxChunkSizeis set too small, andENABLE_SECTION_DETECTIONis not enabled, so section boundaries of the daily report are not identified. - Phenomenon: After uploading an Excel-format financing daily report, field misalignment occurs in vectorization indexing results. Cause: No column mapping rules are configured for Excel parsing, so the correspondence between original document fields and content is not retained.
How to Confirm Proper Configuration
- Upload a single typical consumer building materials financing daily report document, view the parsed chunk list, and confirm that information from the same financing project is not split.
- Check execution logs of batch parsing tasks, confirm that the number of documents processed per batch matches the configured
PARSE_BATCH_SIZE, with no timeout error records. - Upload an Excel-format daily report file, verify that parsed fields match column names of the original document.
- Trigger the knowledge base indexing process, confirm that the field association relationship between chunked content and the original document is not broken.
