What this category of data looks like
Data for gas intelligent due diligence reports primarily comes from gas operation enterprises’ pipeline network GIS ledgers, monthly gas load reports, safety inspection compliance documents, upstream gas supply contracts, and regulatory public information. Data update cycles include fixed intervals (monthly operational data, quarterly compliance reports) and ad-hoc triggers (supplementary reports after pipeline network modifications or sudden safety incidents). Document structures combine structured tables and unstructured text, including fields such as pipeline pressure, leak point coordinates, number of connected households, and gas supply unit price. Some files include high-resolution pipeline drawings.
Constraints on deployment and upgrade
Mixed structured and unstructured document structures require differentiated document parsing rules during deployment. Generic industry single-type parsing configurations cannot be reused directly. Spatial coordinate fields such as leak point coordinates require additional vector database spatial index configuration. Without this, accurate recall of pipeline network nodes is not possible. The combination of fixed-cycle and ad-hoc data updates requires retaining incremental synchronization configuration entries during upgrades. This prevents excessive resource usage from full reprocessing runs. Numeric fields with units need unified formatting before embedding. This stops vector deviation caused by inconsistent unit values. Sensitive pipeline network safety data requires data encryption rule configuration during deployment. This aligns with financial due diligence compliance requirements.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Single large gas due diligence report includes multiple GIS drawings. Parsing takes significant time. This setting avoids task interruption from timeout. |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single annual full due diligence report may include massive ledgers and drawings. This setting accommodates large file upload requirements. |
ENABLE_SPATIAL_VECTOR | Enabled | Gas data includes coordinate fields. Enabling spatial vector indexes enables accurate recall of pipeline network node data. |
SYNC_INCREMENTAL_ENABLE | Enabled | Gas data has monthly fixed updates. Incremental synchronization reduces post-deployment resource usage and synchronization time. |
EMBEDDING_BATCH_SIZE | 32 | Structured table data has many entries. Batch embedding improves overall parsing and embedding efficiency. |
MAX_CONTEXT | 8000 characters | Due diligence reports include long-form compliance descriptions. A sufficient context window ensures complete retrieval. |
The parameter values provided on this page are common starting points 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 errors
- After upgrading to 4.14.3, calling the attachment upload API returns the error
fail to create post presigned url. The cause is failure to synchronously update object storage signature configuration parameters. This makes the configuration incompatible with the new version’s API signature rules. - Knowledge base disk usage continues to exceed expectations. Usage grows even when no incremental files are added. The cause is failure to disable full embedding caching. Repeated generation of embedding vector files occupies significant storage space.
- Model vendor icon loading fails. The interface displays blank placeholders. The cause is failure to configure cross-origin rules for static resource CDN. New version icon resources cannot be retrieved normally.
How to confirm configurations are properly set
- Upload a 1000MB gas GIS drawing report. Verify the upload progress bar completes normally with no timeout errors.
- Check the vector database console. Confirm the spatial index has been created and can retrieve pipeline network data related to coordinates.
- Trigger an incremental synchronization task. Verify only updated monthly data is correctly imported, and no historical files are reprocessed.
- Call the attachment upload API. Verify the returned pre-signed URL can access the uploaded file normally.
