What Data for This Category Looks Like
Data for this category primarily comes from code repositories, app store backends, crash monitoring platforms, and device coverage data. Daily produced documents include end-version release sheets, device adaptation lists, crash analysis reports, and app store submission materials. Data updates follow either a daily sync schedule or per-version iteration cycles. Document structure typically uses fields divided by version number, device adaptation scope, crash type, and app store review status. Corresponding information is only labeled according to business scenarios, with no unified fixed units.
Constraints Imposed on Database and Operations Maintenance
Data for this category comes from multiple dispersed sources. Integration with heterogeneous data sources such as code repositories and app store backends is required, along with adaptation to different interface formats and permission verification rules. Data update cycles vary, with both daily routine syncs and batch updates during version releases. Incremental data pull support is needed to reduce operational maintenance pressure. Document fields are dynamically adjusted with version iterations, so flexible configuration of field mapping rules is required to adapt to different business scenarios. Correlation analysis between device coverage data and crash analysis data requires the database to support multi-table join query capabilities.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PG_URL | postgresql://user:pass@host:5432/dbname?sslmode=require | Adapts to the standard connection format for managed PostgreSQL services, meets cross-environment deployment requirements, and is compatible with FastGPT v4.17.0 |
MONGODB_URI | mongodb+srv://user:pass@cluster.mongodb.net/dbname?retryWrites=true&w=majority | Adapts to the standard connection format for cloud-hosted MongoDB clusters, ensuring connection stability |
DB_MAX_LINK | 20–50 | Matches concurrent query volumes in mobile development scenarios, preventing database connection exhaustion |
REDIS_URL | redis://:password@host:6379/0 | Used to cache frequently accessed device adaptation rules and app store metadata, reducing repeated database query pressure. Cache expiration time is set to 300 seconds |
Three Common Configuration Errors
- Symptom: Connection timeout or authentication failure errors occur after configuring
MONGODB_URI, and network permission issues referenced in official documentation are not resolved. Cause: Outbound ports from the application deployment environment to the MongoDB cluster are not open, or authentication parameters in the connection string are misconfigured. - Symptom: Permission denied errors appear when connecting to a managed PostgreSQL service. Cause: The IP whitelist for the current deployment environment is not configured in the managed service backend, or correct database role permissions are not utilized.
- Symptom: A
text index required for $text queryerror is returned during full-text search. Cause: A full-text index is not created for the associated business fields, preventing the construction of a knowledge base index based on the specified columns.
How to Confirm Successful Configuration
- Run a basic connection test to verify that the configured database connection string can establish a normal connection. This can be completed using the built-in database debugging tool in FastGPT.
- Trigger a version data sync task, and check if synced field mappings match preset rules, with no missing or abnormal fields.
- Initiate a full-text search based on business fields, confirm that the number of returned results does not exceed the preset 100 entries, aligning with the expected query scope.
- View the database connection monitoring panel, confirm that active connection count stays within the range set by
DB_MAX_LINK, with no connection exhaustion.
