What data does this category include?
Core data for this category comes from historical traffic data, service topology diagrams, online monitoring metrics, and business growth plans. Regularly produced documents include technical plans, architecture design diagrams, capacity assessment reports, and technical review minutes. Document structures typically include fields such as version number, effective time, associated service list, and resource configuration thresholds. Data is updated monthly or when major requirements are triggered. Primary users include architects, technical leads, and platform R&D teams. Field units are mostly connections, QPS, storage capacity, time intervals, and similar metrics.
What constraints do these characteristics impose on deployment and upgrade workflows?
Based on the above data characteristics, deployment and upgrade workflows must first match resource thresholds from historical traffic and capacity assessments to avoid configurations exceeding service carrying capacity. Documented architecture designs and review minutes require deployment actions to strictly follow cross-service boundary agreements; established service topologies must not be modified arbitrarily. The data update frequency means upgrades should not be performed too frequently. Complete closed-loop verification of review comments before each upgrade, otherwise system expansion may be restricted or migration costs may increase. Additionally, all configurations must align with the current version’s technical plan to avoid mismatches between configurations and documentation.
How to set configurations
| Config Item | Recommended Approach | Rationale |
|---|---|---|
DB_MAX_LINK | 80–120 connections | Matches peak concurrent connections from historical traffic data, and aligns with database connection rules for FastGPT v4.17.0 |
REDIS_URL | Authenticated cluster deployment address | Complies with cache cluster architecture from the service topology, and ensures high availability of cache access |
STORAGE_S3_ENDPOINT | Storage endpoint in the nearest region | Meets regional deployment requirements from business growth plans, and reduces file access latency |
| File upload validity period | 7 days | Aligns with temporary file retention rules from technical review minutes |
FILE_TOKEN_KEY | 32-byte random string | Meets security configuration key length requirements, and ensures interface call security |
ROOT_KEY | 64-byte administrator key | Meets security configuration requirements for administrator permissions, and aligns with permission rules for FastGPT v4.17.0 |
Three common misconfigurations
- Symptom: Knowledge base images do not appear in search results after update, and no image field is returned in results. Cause: Failed to align with storage service version requirements documented in the architecture design document, and did not correctly configure associated storage parameters.
- Symptom: Database connection errors occur after service startup, showing connection limit exceeded. Cause: Did not reference peak configuration
DB_MAX_LINKfrom historical traffic data, and set connection count below actual concurrent demand. - Symptom: Frontend pages fail to load static resources normally, returning 403 status code. Cause: Did not set
FE_DOMAINaccording to domain name configuration in the architecture diagram, resulting in blocked cross-domain access.
How to verify correct configuration
- Check database connection logs to confirm current concurrent connections do not exceed the configured
DB_MAX_LINKthreshold, which is calibrated based on peak historical traffic data. - Upload and update knowledge base images, verify that access links returned by the storage service can be accessed normally, and match
STORAGE_S3_ENDPOINTconfiguration requirements. - Check cache connection status after service startup, confirm that cluster nodes configured in
REDIS_URLcan connect normally, with thresholds calibrated based on service topology node distribution. - Access the frontend
FE_DOMAINaddress to confirm static resources load normally, matching domain name rules from the architecture design.
