What does the data for this category look like?
Data sources for this category include the national integrated government service platform item database, administrative licensing item list, departmental business approval systems, and electronic certificate repository. The update frequency is daily. Daily generated documents cover service guidelines, application forms, commitment letters, acceptance notices, correction notices, administrative licensing approval decisions, and license certificates. Data fields include item name, applicant information, acceptance number, approval status, completion time, certificate number, and others. Units include pieces, days, unique identifiers, and others. Data formats vary slightly across different sources.
What constraints do these characteristics impose on the database and operations link?
Daily updated data from multiple sources requires the database to support incremental synchronization. This avoids performance pressure from full data pulls. Diverse document types and field differences require the database to support storage of both structured and unstructured data. Severe consequences of errors in government approval workflows require the database to have complete backup and disaster recovery mechanisms. Cross-departmental access to electronic certificate data requires the database to support cross-source data access configuration. Daily update volume and concurrent approval requests also require database connection pool configuration to adapt to business peak loads.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://admin:securepass@mongo-host:27017/approval_ledger?authSource=admin | Stores unstructured data for approval ledgers, such as scanned acceptance notices and text of correction notices |
PG_URL | postgresql://gpt_approval:securepass@pg-host:5432/approval_stats?sslmode=require | Stores structured approval data, such as item lists and completion statistics; government scenarios require SSL encrypted transmission |
DB_MAX_LINK | 15–25 | Adapts to concurrent requests for daily incremental synchronization, prevents database connection exhaustion from affecting approval business |
REDIS_URL | redis://:redispass@redis-host:6379/1 | Caches synchronization task status locks and frequently queried approval item data to reduce database pressure |
Three Common Misconfigurations
- Symptom: FastGPT v4.17.0 fails to start with a MongoDB connection failure prompt. Logs return
Connection refusedor authentication failure errors. Cause: The username, password, or port forMONGODB_URIis not configured correctly, or the MongoDB service is not running properly. - Symptom: Database incremental synchronization tasks fail repeatedly, and synchronization progress cannot advance. Cause:
DB_MAX_LINKis set too low, causing synchronization tasks to fail to acquire enough database connections and triggering connection timeouts. - Symptom: Users cannot enter a port number in the database connection configuration interface, or the port number is automatically cleared after saving. Cause: The input format requirements for the configuration item are not followed, or browser caching causes interface abnormalities.
How to Confirm Successful Configuration
- Run the MongoDB client command
mongo "mongodb://admin:securepass@mongo-host:27017/approval_ledger?authSource=admin"to verify successful login and ability to view collection lists. - Run the PostgreSQL client command
psql "postgresql://gpt_approval:securepass@pg-host:5432/approval_stats?sslmode=require"to verify normal login and basic table query permissions. - Start the preset approval ledger synchronization task, check that the task log has no errors and completes the daily incremental data synchronization.
- Simulate a standard approval process submission operation, verify that data is correctly written to the corresponding database tables and MongoDB collections.
