What this category’s data looks like
This category’s data primarily comes from historical traffic data, service topology, monitoring metrics, and business growth plans. Daily output documents include technical solutions, architecture diagrams, capacity assessment reports, and technical review minutes. Document structure typically centers on constraint conditions, cross-service boundary definitions, and long-term evolution routes as core fields. Some documents include quantitative records of capacity calculations. Update frequency is monthly, or after major requirements are completed.
What constraints these characteristics impose on database and operations workflows
Real-time pulling of historical traffic and monitoring metrics requires database connections to have high availability and low latency. This avoids negatively impacting the accuracy of architecture solution capacity calculations. Monthly or major requirement-level update cycles require databases to support bulk data writes and regular archiving mechanisms. This reduces long-term storage pressure. Mixed storage needs for multiple document types require differentiated storage strategies for structured technical review minutes and unstructured architecture diagrams. Implement access permission controls to prevent core solutions from being tampered with. Cross-service boundary definitions rely on database topology data queries. Maintain stable database access links between services. Avoid connection interruptions to prevent delays in solution reviews.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://[username]:[password]@host:port/database?authSource=admin | Adapts to the non-relational document storage requirements of FastGPT v4.17.0, supports permission verification and specified database instances, used for storing architecture diagrams and unstructured technical solutions |
PG_URL | postgresql://[username]:[password]@host:port/database?sslmode=require | Used for storing structured technical review minutes and capacity assessment data, SSL mode ensures data security during transmission |
DB_MAX_LINK | 20–30 connections | Matches the concurrent volume of bulk data queries and document storage in architecture design scenarios, prevents service interruptions caused by exhausted connection pools |
REDIS_URL | redis://[password]@host:port/0 | Used for caching frequently accessed service topology and monitoring metric data, reduces direct query pressure on primary databases |
Three common misconfigurations
- Symptom:
400 Messages with roleerror returned when calling database tools. Cause: Incorrect role permission configuration forMONGODB_URI, causing the database to fail to recognize the requesting role. - Symptom: No output when calling database tools in a workflow. Cause:
DB_MAX_LINKvalue is too low, new database connections cannot be established after the connection pool is exhausted. - Symptom: Manual SQL execution works normally, but errors occur when passing variables. Cause: Correct parameter escaping rules are not configured via
PG_URL, leading to variable parsing failure.
How to confirm configurations are properly set
- Run a database connection test script to verify that
MONGODB_URIandPG_URLcan establish normal connections and read preset test data. - Check database connection pool monitoring to confirm that current active connections do not exceed the
DB_MAX_LINKconfiguration value, avoiding connection exhaustion. - Upload a technical review minute document to verify that it can be stored normally and the corresponding content can be retrieved via keyword search.
- Configure a cached data synchronization task to verify that cached data via
REDIS_URLcan be synchronized to the primary database per business requirements.
