What data for this category looks like
This category of data is primarily sourced from existing system inventories, domestic software and hardware catalogs, test environments, and publicly available manufacturer materials. Daily produced documents include adaptation lists, compatibility test reports, migration plans, and issue ledgers. Common data fields cover software and hardware models, version numbers, test results, migration times, and similar details. It does not include unstructured business data. The data update rhythm follows individual projects or quarterly cycles. Each update only covers software and hardware within the current adaptation scope and migration progress, and does not involve batch modifications of full historical data.
What constraints these characteristics impose on the "database and operations" link
The data characteristics of this category impose multiple constraints on the database and operations link. First, data sources involve multiple types of domestic software and hardware, requiring the database to be compatible with domestic database protocols in independent innovation environments to avoid database connection compatibility issues in such environments. Second, the update rhythm following projects or quarterly cycles requires the operations link to support incremental data synchronization and version rollback, facilitating risk rollback during migration. Third, documents include compatibility test results and issue ledgers, requiring the database to support structured storage and fast retrieval to support issue troubleshooting during adaptation. Finally, errors may result in business system unavailability or migration delays, requiring the operations link to configure high-availability mechanisms to reduce fault risks at the database level.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | mongodb://[domestic MongoDB username]:[password]@[domestic MongoDB address]:27017/fastgpt?authSource=admin | Adapts to the identity verification and connection format of domestic MongoDB in independent innovation environments, and complies with deployment specifications for independent innovation products |
PG_URL | postgresql://[domestic PG username]:[password]@[domestic PG address]:5432/fastgpt | Adapts to the connection protocol of domestic relational databases, meeting database access requirements after independent innovation replacement |
DB_MAX_LINK | 100–120 connections | Adapts to the single-node resource configuration of 4c16g, avoiding service unavailability caused by connection pool exhaustion |
REDIS_URL | redis://[domestic Redis address]:6379/0 | Adapts to cache services in independent innovation environments, ensuring normal operation of session and vector caching for FastGPT v4.17.0 |
| Database connection timeout | 600 seconds | Adapts to cross-subnetwork network delays in independent innovation environments, avoiding service interruptions caused by connection timeouts |
Three common mistakes
- Symptom: Database connection error, with error log returning
Failed to connect to 192.168.xx.xx.:[port]. Cause: Access permissions for the FastGPT service are not configured in the firewall or database whitelist of the independent innovation environment, resulting in blocked connections. - Symptom: Service unresponsiveness when single-node concurrency reaches 50, with the operations panel showing exhausted database connection counts. Cause: The
DB_MAX_LINKconfiguration value is lower than the actual business concurrency requirements, and the connection pool upper limit is not calibrated according to resource conditions in the independent innovation environment. - Symptom: Cache service exception after PDF parsing is triggered. Cause:
REDIS_URLis not configured to point to the domestic cache service, and the default open-source Redis address is still used, resulting in abnormal cache read and write operations in the independent innovation environment.
How to confirm configurations are correct
- Run the database connection test script to verify that the configurations for
MONGODB_URIandPG_URLcan successfully establish connections and read/write data. - Check the database connection count metric on the operations monitoring panel to confirm that the current active connection count does not exceed the
DB_MAX_LINKconfiguration value. - Review the cache service logs to confirm that the domestic Redis configured via
REDIS_URLcan normally receive and process read/write requests. - Simulate business traffic in the independent innovation environment, gradually increase concurrency levels, and verify service stability under the set thresholds.
