What the data for this category looks like
Chemical raw material investment research data sources include public statistical materials from domestic chemical industry associations, production capacity data disclosed by upstream manufacturers, import and export trade data from national customs, daily quotes from spot trading platforms, and safety data sheets and process parameter documents included in professional databases.
Update frequencies vary: spot quotes are updated daily, industry capacity statistics are updated quarterly, and patents and compliance documents are collected in real time.
Document structures include structured standard tables and unstructured research reports and compliance description documents. Fields include CAS number, production capacity, quote, and process parameters. Units are 10-character sequences, 10,000 tons per year, yuan per ton, respectively. Process parameters are marked with temperature and pressure values.
Constraints Imposed on Deployment and Upgrade
Multi-source data with differing update frequencies requires configuring multi-source synchronization scheduling rules during deployment, and defining synchronization cycles for each data source. During upgrades, compatibility with parsing formats for new data sources must be maintained, to avoid data parsing failures caused by format mismatches.
Mixed structured and unstructured documents require configuring differentiated text chunking strategies, to avoid parsing timeouts for long documents.
Standardized field and unit requirements require presetting field mapping rules during deployment. During upgrades, field verification logic must be updated synchronously, to prevent disordered data formats after parsing.
Daily updated spot data requires configuring an incremental synchronization mechanism, to avoid excessive resource usage from full pulls. During upgrades, the trigger logic and verification mechanism for incremental synchronization must be optimized.
How to Set Configuration Values
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Safety data sheets and industry research reports for chemical raw materials are often lengthy. 600 seconds covers parsing requirements for most long documents |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Some large industry research reports or bulk data files have large file sizes. 2000 MB meets requirements for bulk uploads and single-file parsing |
rag_chunk_size | 800–1200 characters | Chemical raw material documents contain many technical terms and long sentences. This chunking interval preserves semantic integrity and prevents term truncation |
rag_similarity_threshold | 0.75–0.85 | Professional investment research data has high correlation requirements. This interval filters low-relevance non-professional content and improves retrieval accuracy |
incremental_sync_interval | 1440 minutes | Spot quotes are updated daily. A 1440-minute (24-hour) synchronization interval ensures timely data synchronization while reducing resource usage |
field_mapping_template | Preset field mappings for CAS number, production capacity, and quote according to chemical industry standards | Chemical raw material data uses standardized fields. Preset mappings reduce manual configuration workload and prevent field format errors |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing values.
Three Common Misconfigurations
- Symptom: After deploying a custom PDF parsing service, parsing chemical raw material safety data sheets returns a 504 timeout error. Cause:
PARSE_FILE_TIMEOUT_SECONDSwas not configured to a duration compatible with the custom service. FastGPT actively terminates unfinished parsing requests. - Symptom: No button to edit recalled snippets appears in the knowledge base retrieval test page. The segmentation configuration must be adjusted in the knowledge base content management page. Cause: The
rag_debug_modeparameter was not enabled during deployment, causing the debug entry to be hidden. Direct adjustment of indexing parameters on the retrieval page is not possible. - Symptom: No new user registration entry appears after open-source deployment, or the registration page returns a 404 error. Cause:
ENABLE_SIGNUPwas not configured astruein the environment variables. Registration functionality is disabled by default. Adjust this parameter during upgrades or redeployment.
How to Verify Proper Configuration
- Upload a typical chemical raw material safety data sheet or industry research report, and check that the parsed text chunks match the preset configuration. Confirm that technical terms are not truncated.
- Trigger an incremental synchronization task, and review the synchronization logs. Confirm that only data from the update time period was synchronized, with no full repeated pulls.
- Access the system registration page. Confirm that the new user registration process completes normally when registration functionality is enabled.
- Run the official security scanning tool. Confirm that the dependent NextJS framework version has been updated to the official security fix release, with no CVE-2024-46982 related alerts.
