What this category of data looks like
Grain reserve policy and regulatory basis data is primarily sourced from official documents issued by the National Food and Strategic Reserves Administration, local grain management departments at all levels, regulations on reserve grain management, annual reserve supervision documents, and special policy notices. Data updates follow no fixed cycle, and are performed in real time when new policies are released or reserve rules are adjusted. Document structures include fields such as policy document number, issuing authority, effective date, applicable scope, clause classification, and execution standards. Some long documents contain multi-chapter detailed rules. Units cover physical and monetary indicators including tons, yuan per ton, and reserve scale.
Constraints during deployment and upgrade
The long text and multi-field characteristics of grain reserve policy data require deployment to support vector parsing and storage of complex documents, to prevent loss of key clauses during retrieval. The non-fixed update cycle requires configuring flexible scheduled synchronization tasks to meet synchronization needs for temporarily released policies. The internal network deployment scenario for state-owned enterprises and public institutions requires avoiding exposure of public network resources. All databases, caches, and storage services must be bound to internal network addresses. The total data volume grows gradually with policy updates, so sufficient system resources must be reserved to support subsequent knowledge base expansion and upgrade operations.
How to set configurations
| Configuration Item | Suggested Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | The total volume of grain reserve policy documents grows gradually with updates. The database connection pool must accommodate concurrent retrieval requests to avoid retrieval failures caused by exhausted connections |
MONGODB_URI | Internal MongoDB cluster address with access authentication parameters | Complies with internal network data security requirements for state-owned enterprises and public institutions, to avoid exposing policy document data over public networks |
REDIS_URL | Internal Redis cache address, set 600-second expiration time | Cache frequently retrieved policy clauses to reduce repeated database queries and ensure question-and-answer response speed |
FE_DOMAIN | Internal access domain name or local area network IP:port | Complies with internal network access scenarios for state-owned enterprises and public institutions, resolving the issue where public network domain names cannot be loaded within the internal network |
STORAGE_S3_ENDPOINT | Internal object storage service address | Store original policy documents and vector indexes, ensuring the security of internal network data transfer |
FILE_TOKEN_KEY | Set based on actual testing | Accommodates authentication requirements for internal network file downloads, preventing unauthorized access to policy document attachments |
Three common configuration mistakes
- Phenomenon: The page can be accessed normally via 127.0.0.1 after deployment, but cannot be loaded using the local area network IP. Cause:
FE_DOMAINis not configured as the local area network IP or internal domain name. Front-end resources are bound to the local address, resulting in inaccessibility within the internal network. - Phenomenon: A large number of retrieval timeout errors occur during cluster deployment. Cause:
DB_MAX_LINKis not adjusted to accommodate cluster concurrent requests. Insufficient database connection pool causes request queuing and blocking. - Phenomenon: Missing clauses or parsing failures occur in synchronized policy documents. Cause:
STORAGE_S3_ENDPOINTis not configured to point to the internal storage service. Original documents cannot be pulled and parsed normally.
How to confirm configurations are correct
For FastGPT v4.17.0, use the following steps to verify configuration status:
- Enter the configured
FE_DOMAINaddress on any internal network terminal to confirm the page loads normally with no abnormal errors. - Run the built-in database connection test script to confirm the connection status of
MONGODB_URIandREDIS_URLis normal. - Upload a grain reserve policy document, trigger a manual synchronization task, and confirm the document can be retrieved normally with complete fields.
- Check the internal network object storage directory to confirm the storage service pointed to by
STORAGE_S3_ENDPOINThas generated synchronized document index files.
