What the data for this category looks like
Data originates from full-process declaration materials and archived files for telecommunications engineering construction projects. This includes project approval documents, construction permits, budget statements, acceptance test reports, as-built drawings, and similar items. Update frequency aligns with project approval milestones. Individual materials are updated repeatedly during the submission verification phase, and enter static storage after archiving. Document structure primarily mixes structured forms, unstructured text, and binary drawings. Fields include project ID, construction location, investment amount (unit: ten thousand yuan), construction period (unit: days), acceptance pass indicator, and more. Some large files require separate storage.
What constraints these characteristics impose on deployment and upgrade
Declaration materials for telecommunications engineering construction include structured forms and unstructured drawings, with wide variations in individual file sizes. Deployment must balance adaptive configuration for relational databases and object storage. Project materials are updated in stages alongside approval milestones. Upgrade processes must avoid interrupting ongoing review tasks, so a rolling upgrade strategy is required. Fields include fixed-unit numeric information. Databases must have strict field validation rules configured to ensure matching between units and data types. Large as-built drawings and budget files must be stored via object storage. Upgrades must maintain compatibility with legacy storage path read logic to prevent archived materials from becoming inaccessible.
How to configure settings
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Telecommunications engineering declaration materials have high volumes of batch verification requests, requiring support for high-concurrency database connections |
MONGODB_URI | mongodb://[username]:[password]@[host address]:27017/fastgpt?authSource=admin | Stores unstructured file scans and approval logs, requiring a stable document database connection |
PG_URL | postgresql://[username]:[password]@[host address]:5432/fastgpt | Stores structured project field information, requiring support for strict numeric and unit validation |
STORAGE_S3_ENDPOINT | https://s3-[region].amazonaws.com or private object storage endpoint | Stores large as-built drawings and budget files, requiring S3-compatible object storage services |
FILE_TOKEN_KEY | Random 32-character string | Generates temporary tokens for material downloads, preventing unauthorized access to sensitive engineering construction files |
REDIS_URL | redis://:[password]@[host address]:6379/0 | Caches frequently verified project IDs and approval statuses to reduce database load |
Three common configuration errors
- Symptom: After deploying on Windows, a device restart results in empty model configurations and application list. Cause: The data storage directory was not mounted to a non-system partition. System disk temporary storage for configurations and business data is automatically cleared after restart.
- Symptom: When upgrading a docker-compose deployed instance, adding environment variables results in failed startup with a prompt indicating missing required configuration items. Cause: Corresponding environment variables were not properly declared in service configurations, or custom parameter names not included in the official manifest were used.
- Symptom: After batch submission of declaration materials, conversation token consumption statistics show no valid data, or the review interface fails to load with a 503 status code. Cause: The
FILE_TOKEN_KEYtoken generation logic was not properly configured, or the database connection pool configurationDB_MAX_LINKwas set too low, causing request queuing timeouts.
How to confirm successful configuration
- Run the
docker pscommand, confirm that all FastGPT-related services have a running status of Up, with no abnormal exits or restart records. - Upload a standard telecommunications engineering construction declaration material, such as an as-built drawing scan, verify that the file can be uploaded, stored, and downloaded normally, with no permission or storage errors.
- Submit a project data entry containing structured fields, verify that numeric information with units is correctly stored in the database, with no validation errors for mismatched types.
- Check database connection monitoring metrics, confirm that active connection count does not exceed the configured
DB_MAX_LINKthreshold, with no connection timeout or rejection errors.
