Online Troubleshooting and Post-Mortem for Customer Onboarding and Tenant Initialization: Database and Operations

What the data for this category looks like

Data for this category primarily comes from CRM systems, contract order databases, identity management systems, and product backends. Daily generated documents include onboarding application forms, tenant configuration sheets, administrator account lists, and delivery confirmation slips. Data updates occur per order or daily. Core fields include tenant unique identifier, customer association information, basic permission configurations, account status, and onboarding timestamp. No additional statistical quantitative indicators are included.

Multi-source data access requires databases to support cross-system synchronization configurations, to avoid data inconsistency. The per-order or daily update rhythm requires reasonable configuration of database connection pool parameters to prevent connection exhaustion. Uniqueness checks for core fields require databases to create unique indexes for tenant ID and customer identifier fields, to avoid duplicate initialization. This link directly relates to customer login and delivery progress, so databases require high availability redundancy configurations to ensure stable metadata read and write operations.

How to set the configurations

Configuration ItemRecommended ApproachRationale
MONGODB_URIFull connection string containing authentication information and exclusive database nameStores core metadata such as tenant accounts and permission configurations, complies with FastGPT v4.17.0 storage specifications
PG_URLStructured data connection address with read-only permission sub-accountStores form data such as onboarding application forms and delivery confirmation slips, separates read and write permissions to enhance security
DB_MAX_LINK50-100 connectionsMatches per-order or daily update rhythm, prevents database connection exhaustion in high-concurrency scenarios
REDIS_URLDedicated cache connection address with access password, set connection timeout to 30 secondsCaches tenant sessions and temporary configurations, reduces response latency for high-frequency queries
Database unique indexCreate indexes for tenant ID and customer identifier fieldsEnsures efficiency of data uniqueness checks, avoids duplicate initialization records
Database idle timeout300 secondsReduces invalid connection occupancy, optimizes database resource utilization
Session cache expiration time1800 secondsMatches the lifecycle of tenant sessions, avoids resource occupation by invalid cache

Three common mistakes

  • Phenomenon: The console returns the text index required for $text query error, and knowledge base initialization fails. Cause: No full-text index was created in the corresponding PostgreSQL table, preventing normal execution of configuration retrieval.
  • Phenomenon: MongoDB connection fails, and the interface prompts authentication error or connection timeout. Cause: The MONGODB_URI configuration does not include correct database authentication information or target database name, or DB_MAX_LINK is set too small leading to connection exhaustion.
  • Phenomenon: Existing tenant data cannot be read normally after upgrading the system version. Cause: No database metadata backup was performed before the upgrade, or the configuration points to an incorrect database instance.

How to confirm configurations are properly set

  • In the FastGPT v4.17.0 system backend, enter the tenant configuration module, perform a database connection test, and verify that the MONGODB_URI and PG_URL configurations can establish normal connections.
  • Log in to the target database, check the index list, and confirm that unique indexes have been created for the tenant ID and customer identifier fields.
  • Submit a test onboarding application form, verify that data can be normally written to the corresponding database table and cross-system synchronization is completed.
  • Enter the Redis cache management page, confirm that the REDIS_URL configuration can normally read and write cache data, and the session cache expiration time meets preset requirements.
