What this category of data looks like
This category of data typically originates from historical traffic data, service topologies, monitoring metrics, and business growth plans. Daily produced documents include technical solutions, architecture diagrams, capacity assessment reports, and technical review minutes. The document structure centers on core fields such as constraints, boundary definitions, and evolution paths. There are no unified fixed units, and some fields require customization based on specific business scenarios. Data is updated once per month or when triggered by a major requirement, and will be regenerated as business scale adjusts or architecture iterations occur.
What constraints do these characteristics impose during deployment and upgrade
Data for this category is linked to the long-term evolution of the architecture and cross-service boundaries. During deployment and upgrade, configurations must be aligned with historical traffic and service topologies. Since data update frequency is low but dependent on business growth plans, the latest capacity assessments and monitoring metrics must be synchronized prior to upgrading to avoid mismatches between configurations and current business scale. Constraints listed in architecture diagrams and review minutes impact parameters such as container resource allocation and database connection counts. Failure to align these may result in restricted system expansion or increased migration costs. Additionally, cross-service architecture design must ensure consistency of configurations across all links to prevent configuration gaps.
How to configure settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 | Matches the peak concurrent connections in historical traffic data to avoid connection pool exhaustion |
MONGODB_URI | Assembled using the intranet address of the deployment environment, with authentication parameters included | Adapts to the database topology defined in the architecture design, ensuring data read/write permissions and link security |
REDIS_URL | redis://:custom password@intranet address:6379/0 | Corresponds to the deployment location of the cache service in the architecture diagram, providing a stable link for context caching in ticket Q&A |
ROOT_KEY | Generate a random string in accordance with the security specifications in the technical review minutes | Follows the permission constraints in the architecture plan to secure access to the platform management interface |
STORAGE_S3_ENDPOINT | Select nodes in the corresponding region based on storage requirements in the capacity assessment | Aligns with storage expansion plans in business growth plans to reduce subsequent migration costs |
Three common misconfigurations
- After upgrading to FastGPT v4.17.0, some uploaded knowledge base tables cannot be chunked normally. This occurs because document processing constraints defined in the architecture design are not aligned, and the chunking logic from older versions does not adapt to the new text extraction rules.
- When deploying using the OceanBase version of compose.yml, the fastgpt container fails to start and no valid log output is produced. This occurs because the
MONGODB_URIconfiguration does not match the database topology defined in the architecture diagram, causing an abnormal connection link. - During on-call operations, a large number of interface timeout alerts are received, and the Q&A interface returns the
Reached the max retrieserror. This occurs because theDB_MAX_LINKconfiguration value is lower than the peak concurrent connections in historical traffic data, leading to database connection pool exhaustion.
How to confirm configurations are correct
- View container startup logs to confirm that database and cache service connection statuses are normal, with no connection failure errors.
- Upload a test document containing tables to verify that chunking results conform to the document processing rules defined in the architecture design.
- Simulate the peak concurrent connections from historical traffic data to verify that interface call retry counts do not exceed the configured threshold.
- Check the access permissions of the management interface to confirm that the validation logic for the
ROOT_KEYconfiguration is working correctly.
