What Data for This Category Looks Like
This category of data originates from historical traffic data, service topologies, monitoring metrics, and business growth plans. Updates occur monthly or when major requirements are triggered. Daily deliverables include technical solutions, architecture diagrams, capacity assessment reports, and technical review minutes. Data fields cover constraint conditions, solution demonstration records, review opinions, resource requirements, and similar items. Common units include QPS, CPU core count, and memory capacity. The overall structure combines structured and semi-structured formats, supporting long-term architecture decisions across service boundaries.
Constraints Imposed on Database and Operations Workflows
Diverse data sources and semi-structured formats require databases to support flexible field expansion and multi-source data access. Non-real-time updates with batch query peaks demand stable connection pool management to prevent connection exhaustion from sudden requests. Cross-service topology and review records require tiered storage to separate metadata and business data, while enabling data version traceability. Troubleshooting and retrospectives for architecture solutions rely on fast historical monitoring data queries. Optimize database indexes to match high-frequency query scenarios and cut down troubleshooting time.
How to Set Configurations
All configurations below are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | Configure as the intranet access address, with username and password authentication parameters included | Used to store knowledge base metadata and architecture solution documents. Intranet deployment reduces public network access risks, and authentication ensures data access security |
PG_URL | Associate with the access address of the business monitoring database, set connection timeout to 30 seconds | Used to store structured monitoring data such as historical traffic and service topologies. The timeout setting adapts to batch data pull scenarios for monitoring data |
DB_MAX_LINK | Set to 80–120 | Matches the concurrent query peak of architecture solution documents, avoiding service freezes or request failures caused by connection exhaustion |
REDIS_URL | Configure as the local cache node address, set key expiration time to 600 seconds | Used to cache architecture review opinions and capacity assessment results from high-frequency queries, reducing repeated query overhead for the database |
Three Common Misconfigurations
- Symptom: When uploading a knowledge base parsing file, logs continuously report slow operation xxxxms errors, and MongoDB responds slowly. Cause: The
DB_MAX_LINKparameter is not adjusted, leading to insufficient database connections that cannot handle concurrent batch document parsing requests in a timely manner. - Symptom: The dataset.csv exported from the knowledge base only contains the index field and no content field. Cause:
MONGODB_URIis not correctly configured to point to the storage collection corresponding to the knowledge base, causing the content field to not be read and exported properly. - Symptom: Request success rate is low in high-concurrency scenarios, failing to meet business peak requirements. Cause: The cache expiration policy for
REDIS_URLis not optimized, leading to frequent repeated database queries and causing database performance bottlenecks.
How to Verify Configurations Are Correct
- Access the database management tool to verify that connections configured via
MONGODB_URIandPG_URLestablish successfully, and read business data from the corresponding collections. - Execute a batch document parsing test, observe whether slow operation errors disappear in the logs, and confirm that the
DB_MAX_LINKconfiguration takes effect. - Review the cache monitoring panel to confirm that the cache node corresponding to
REDIS_URLhas hit records, and verify that the cache policy operates correctly. - Export a small knowledge base dataset, check whether the generated CSV file includes the content field, and confirm that the database connection configuration is correct.
