What constraints do these characteristics impose on the deployment and upgrade phase
Document characteristics of telecommunications engineering construction impose multiple constraints on the deployment and upgrade phase. First, data sources are scattered across multiple internal systems. Cross-source synchronization rules must be configured during deployment to ensure documents from different channels are unified into the parsing workflow. Second, documents update with project phases. Incremental data migration must be supported during upgrades to avoid excessive storage and compute resource usage from full data pulls. Third, documents include specialized fields such as base station ID and construction area. Field mapping rules must be preset during deployment to prevent field matching errors during parsing. Fourth, single-project documents contain large numbers of binary attachments. Storage-related configurations must be adjusted during deployment to adapt to large file read/write requirements.
How to configure settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 connections | Telecommunications engineering document parsing has periodic concurrency peaks. A reasonable connection pool upper limit prevents database connection exhaustion |
REDIS_URL | redis://:custom password@deployment server:6379/0 | Used to cache document metadata and parsing results to reduce repeated computation overhead, adapting to high-frequency read/write scenarios |
STORAGE_S3_ENDPOINT | http://minio.internal:9000 (calibrated via actual testing) | Telecommunications engineering documents include large numbers of drawings, on-site photos, and other binary files. S3-compatible storage meets large file storage requirements |
FILE_TOKEN_KEY | 32-character random string | Used to sign document upload credentials to prevent unauthorized access to sensitive construction-related materials |
FE_DOMAIN | https://comm-eng-docs.example.com | Bind a dedicated internal domain name to resolve cross-origin access issues and ensure normal use by project personnel |
ROOT_KEY | Complex random string of at least 16 characters | Used for highest-privilege verification of the management backend to ensure configuration permission security after deployment |
Three common configuration errors
- Phenomenon: After uploading telecommunications engineering documents, the parsing result shows empty, with output content
none. Cause:FILE_TOKEN_KEYis not configured correctly. Upload credential verification fails, and files are not properly stored to the target path. - Phenomenon: When batch parsing construction drawing documents, the system frequently reports connection exhaustion errors. Cause:
DB_MAX_LINKis set too low, failing to adapt to periodic high-concurrency parsing requests. - Phenomenon: After version upgrade, documents from some historical projects cannot be retrieved normally. Cause: Incremental metadata migration was not performed during upgrade. Only core configuration files were overwritten, resulting in loss of index information for older documents.
How to confirm configuration is complete
- Upload a test document in the format of a telecommunications engineering base station construction review form, verify no upload errors occur and the file can be retrieved normally on the storage node.
- Trigger a document parsing task, check if the parsing result includes specialized telecommunications engineering fields such as project number and base station ID, with no null values returned.
- Log in to the FastGPT management backend using
ROOT_KEY, verify permission configuration is normal, and the document management module can be accessed normally. - Simulate periodic concurrency parsing requests, observe system monitoring metrics, confirm connection pool and storage configurations meet current business requirements.
