What the Data for This Category Looks Like
Policy and regulatory basis data for the advanced chemical materials sector is sourced from official policy documents issued by the Ministry of Industry and Information Technology and the National Development and Reform Commission, industry association standard texts, and compliance notices from local industrial and information departments. The update cadence is monthly synchronization of newly released compliance documents. Most documents are structured PDFs or structured text that include document numbers, issuing entities, and effective dates. Fields include policy ID, applicable sub-scenarios, core compliance clauses, and penalty basis. Units are primarily the sequence number from the document number, standard format of effective dates, and clause entry numbers. The size of individual documents ranges from 100 KB to 50 MB.
Constraints Imposed on Deployment and Upgrade by These Characteristics
Policy document formats are inconsistent and mostly structured text. During deployment, configure parsing rules that support multiple formats to ensure complete extraction of core compliance clauses. The monthly update feature requires the upgrade process to support incremental synchronization mechanisms, avoiding full pulls that consume excessive storage and bandwidth resources. Storage requirements for long-text compliance clauses require adjusting the segmentation rules for vector ingestion to prevent truncation of critical compliance information. Index requirements for fields such as policy ID and effective date require pre-configuring index strategies for the corresponding database to ensure retrieval speed. Additionally, access control requirements for sensitive policy documents require configuring unified permission verification logic during the deployment phase.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 500–800 entries | Advanced chemical materials policy documents are mostly collections of long-text links. This parameter controls the upper limit of links processed per batch to avoid memory overflow |
MONGODB_URI | mongodb://username:custom_pass@host:27017/fastgpt_polymer_materials?authSource=admin | Stores policy document metadata and vector indexes. A permission-verified connection address must be configured to ensure data security |
REDIS_URL | redis://:custom_redis_pass@host:6379/0 | Caches frequently retrieved policy clause results to reduce database query pressure. An access password must be configured to ensure cache security |
STORAGE_S3_ENDPOINT | Fill in according to the local object storage service provider address | Stores original policy documents and parsed structured data. Must match the storage service address of the deployment environment |
FILE_TOKEN_KEY | Randomly generated 32-bit string | Generates access tokens for policy documents to prevent unauthorized access to sensitive policy files |
Three Common Errors
- Phenomenon: Network timeout or image not found errors occur when pulling the FastGPT v4.8.15-fix2 Docker image. Cause: This version of the image is only published in the official image repository, and pulling fails because no domestic image acceleration address is configured.
- Phenomenon: After deploying the overseas SaaS version, the login-free shared policy Q&A link fails to respond normally and returns a 404 status code. Cause: The sharing configuration is not bound to the correct frontend domain
FE_DOMAIN, leading to route matching failure. - Phenomenon: The number of returned results when searching for compliance clauses is much lower than expected. Cause: No reasonable upper limit for
DB_MAX_LINKis configured, causing some long documents to not be fully loaded and ingested.
How to Confirm Proper Configuration
- Run the
docker pull fastgpt/fastgpt:v4.17.0command to confirm that the specified version of the image can be pulled normally without timeouts or errors. - Access the shared link corresponding to the configured
FE_DOMAINto verify that the login-free window loads normally and returns policy Q&A results. - Upload an advanced chemical materials policy document, wait for parsing to complete, then perform a search to confirm that the number of returned results matches expectations.
- Check the database connection logs to confirm that the connection status for
MONGODB_URIandREDIS_URLis normal, with no error messages.
