What the data for this category looks like
Business processing data for general contracting of housing construction projects comes primarily from project management systems, housing and urban-rural development department approval platforms, and internal approval ledgers. Update timing aligns with project progress milestones. A single submission document typically includes section division, construction area scope, and process progress details. Documents use structured tables and sectioned explanations primarily, with fields including section number, construction area (unit: square meters), submission process name, approval node status, and submission date. The length of a complete project submission document usually ranges from 5000 to 15000 characters. Documents with drawing attachments can reach a size of over 1000 MB.
What constraints these characteristics impose during deployment and upgrade
Business processing documents for general contracting of housing construction projects have wide length ranges and include large numbers of structured tables and specialized terminology. Deployment must support long-text parsing and specialized word vector matching capabilities. Uncertain update rhythms require the deployed vector database to support dynamic scaling, to avoid index blocking during peak periods. For scenarios with parallel submissions across multiple sections, sufficient concurrent processing resources must be configured to prevent single-node overload. During upgrades, the original field mapping rules for project approval ledgers must be retained, to avoid failure to associate historical data normally. Compatibility must also be maintained with changes to the interface format of housing and urban-rural development department approval platforms, to prevent failure to synchronize official approval status after upgrade.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 200–300 connections | Adapts to parallel business processing requests initiated by multiple housing construction project sections, and prevents database connection pool exhaustion |
REDIS_URL | redis://:custom password@intranet host address:6379/0 | Used to cache approval node status and user sessions, to ensure response speed under high concurrency |
STORAGE_S3_ENDPOINT | Configure according to the intranet address of the internal object storage service provider | Stores submission drawings, progress photos, and other attachments for housing construction projects. Intranet deployment reduces transmission latency |
MONGODB_URI | mongodb://username:custom password@intranet host address:27017/fastgpt?authSource=admin | Stores project approval ledgers and process logs, and supports structured queries |
FILE_TOKEN_KEY | Randomly generated 32-bit string | Used to sign file upload tokens, to prevent unauthorized access to project attachments |
ROOT_KEY | Complex key configured according to enterprise internal security specifications | Manages the highest system permissions, and ensures the security of configuration permissions for business processing workflows |
Three common mistakes
- Issue: After upgrading FastGPT v4.17.0, the m3e model cannot initiate call requests normally. Logs show the model interface returns a 404 status code. Cause: The interface address in the model configuration file was not updated synchronously during the upgrade, causing it to point to a deprecated model service address.
- Issue: When deploying FastGPT via Docker, the file parsing module reports split-related error logs, and uploaded housing construction project submission documents cannot generate valid vector databases. Cause: The correct file parsing temporary directory was not mounted during deployment, causing the split operation to fail to read the document content to be processed.
- Issue: When attempting to upgrade FastGPT in a network-free environment, the upgrade script cannot pull dependency images, and the deployment process interrupts. Cause: The upgrade script pulls components from the public image repository by default, and no local image source path is configured, causing the upgrade to fail in an offline environment.
How to confirm configurations are correctly set
- Initiate a simulated upload of a housing construction project submission document, and check whether the file parsing module logs show that the split operation completed successfully with no error messages.
- Submit a test request for a business processing workflow, and verify whether index entries for the corresponding document are generated in the vector database, and that the fields match the structure of the uploaded document.
- View the system's database connection pool monitoring panel, confirm that the number of connections configured via
DB_MAX_LINKdoes not become exhausted, and that concurrent request processing has no significant latency. - Test calls to the locally deployed large model interface, and confirm that the guidance replies for the business processing workflow can correctly associate process, progress, and other content from the project documents.
