What this category’s data looks like
This category’s data primarily comes from landing page access logs, heatmap data, form submission data, and ad source parameters. Daily associated documentation includes landing page plans, event tracking requirement documentation, AB test reports, and form field lists. Data update frequency is typically weekly, or updated per individual marketing campaign node. Data fields include page path, dwell time, form field submission status, ad channel identifiers, and other fields. There are no unified fixed units; some fields use characters, counts, or timestamps.
Constraints on database and operations workflows
Scattered data sources include unstructured logs and form data. This requires databases to support multi-source data access and format conversion. Update frequency fluctuates with marketing campaigns. Operations configurations must support elastic scaling to avoid connection overload during peak periods. Daily associated document field lists must be strictly aligned with database table structures. Field consistency must be regularly verified to prevent data misalignment. Ad source parameters may contain special characters. Database character sets and collation rules must be configured to avoid data import errors. Troubleshooting requires linking multi-source data, which means databases need to support cross-table join queries. This increases operational complexity and troubleshooting difficulty.
How to Set Configurations
This document is written based on FastGPT v4.17.0. The following are database and operations configuration guidelines for this scenario:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PG_URL | postgresql://user:pass@host:5432/landing_page_db?sslmode=require | Adapts to storage requirements for structured landing page forms and ad parameters; sslmode=require ensures data transmission security |
MONGODB_URI | mongodb://user:pass@host:27017/landing_logs?retryWrites=true&w=majority | Adapts to storage requirements for unstructured access logs and heatmap data; retry mechanism ensures write stability |
DB_MAX_LINK | 20–30 connections | Matches weekly or campaign-level data update peaks; prevents service interruptions caused by exhausted connection pools |
REDIS_URL | redis://:pass@host:6379/0 | Used to cache frequently accessed ad source parameters and form field mappings; reduces database query pressure |
Three Common Misconfigurations
- Symptom: Returns
400 Messages with roleerror when calling the database plugin. Cause: The passed SQL statement contains unescaped special characters, or variable parameters are not correctly bound, leading to abnormal role field formatting. - Symptom: No output is returned after calling a database connection for a locally deployed FastGPT. Cause:
DB_MAX_LINKis configured too low, causing connection pool exhaustion and request blocking, orPG_URLlacks correct database access permission configuration. - Symptom: Manual SQL execution works normally, but an error is triggered when passing SQL via variables. Cause: Variables are not safely escaped, resulting in SQL syntax errors, or the database connection’s parameter binding logic does not correctly adapt to variable types.
How to Verify Successful Configuration
- Run a database connection test script to verify connectivity for
MONGODB_URIandPG_URL, and confirm returned results match expected formats. - Import a test set of landing page access log data, check that data can be written to the database normally, and that fields align with the preset form field list.
- Simulate concurrent requests during campaign peak periods, observe changes in database connection counts, and confirm
DB_MAX_LINKvalues can support peak load. - Configure a variable binding test, pass ad source parameters with special characters, and verify data has no format abnormalities after being imported.
