What the data for this category looks like
Data is sourced from the engineering construction project approval management system, construction drawing review system, enterprise qualification database, and credit platform, with a daily update frequency. Daily processed documents include construction permit applications, construction drawing review qualification certificates, quality and safety supervision procedures, and completion acceptance record forms. Documents contain fields such as approval nodes, participating construction unit qualifications, personnel information, and material verification status. The length of individual documents varies widely, ranging from hundreds to thousands of characters. Some documents include structured approval forms and unstructured explanatory text.
What constraints these characteristics impose on deployment and upgrade
Since data sources include multiple business systems and are updated daily, configure multi-source data synchronization links during deployment. During upgrades, ensure compatibility with new system interface formats to prevent data synchronization interruptions. Daily document structures vary significantly, so adapt parsing rules for different documents during deployment to avoid field extraction deviations. The accuracy of approval-related data directly impacts business processes. Configure reliable storage and verification logic during deployment. During upgrades, do not destroy existing data association relationships. The party building learning Q&A must link approval business and the party building knowledge base. Ensure the linkage logic remains stable during deployment and upgrade to ensure Q&A content aligns with party building requirements for approval scenarios.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | Point to the locally deployed approval business database cluster | Business data storage volume is large, requires support for high-concurrency read/write and daily incremental synchronization |
REDIS_URL | Configure as a local cache instance, set memory quota to 8000 MB | Used to cache approval node data and party building Q&A association results for high-frequency queries, reducing database pressure |
DB_MAX_LINK | Set to 200 | Adapt to concurrent connection requirements for multi-system synchronization, avoid data synchronization interruptions caused by connection exhaustion |
STORAGE_S3_ENDPOINT | Point to the internal object storage service address | Used to store uploaded approval documents and party building learning materials, complies with internal data storage specifications |
FILE_TOKEN_KEY | Configure as the same key used by the approval system | Ensure consistent identity verification for document upload and parsing, prevent unauthorized access |
ROOT_KEY | Set according to the internal permission system | Restrict modification permissions for core configurations, avoid accidental disruption to business and party building Q&A services |
Three common mistakes
- Phenomenon: After upgrading FastGPT v4.17.0, the reply length of party building Q&A becomes shorter, and cannot fully cover policy requirements related to approval. Cause: The original context length configuration was not retained during the upgrade, causing the reasoning length parameter to be reset to the default value.
- Phenomenon: When calling the MCP service, the type of the participating construction unit qualification field is fixed as a string, and the digital qualification number cannot be correctly extracted. Cause: No custom field mapping rules were configured during deployment, and default parameter settings for general scenarios were used.
- Phenomenon: After uploading a completion acceptance record form, the parsing process times out after 2 minutes and displays a request failure. Cause: The expiration time of the identity verification key was not adjusted, causing identity verification to fail during the parsing process and triggering request interception.
How to verify proper configuration
- Log in to the FastGPT backend, check the connectivity of
MONGODB_URIandREDIS_URL, and verify whether daily updated approval business data can be retrieved. - Upload a construction permit application document, trigger a party building Q&A query, and check whether the reply content includes party building requirements for the corresponding approval process.
- Call the MCP service, attempt to pass in the qualification number field, and confirm that the field type can be adjusted customizably.
- Upload a large-volume completion acceptance record form, verify that no timeout errors occur during the parsing process.
