What the Data for This Category Looks Like
Data primarily comes from commercial property leasing management systems, merchant operation ledgers, in-store foot traffic counting devices, and online marketing material libraries. There are two update cadences: Merchant basic information updates in real time as tenants move in, move out, or adjust lease terms. Foot traffic data syncs to the system hourly. Marketing materials are updated in batches per monthly or quarterly campaign plans.
Each data entry includes merchant ID, merchant business category, leased area (unit: square meters), average daily in-store visits, links to past marketing materials, and campaign period fields. Some materials include delivery channel and target user profile tags.
Constraints Imposed on Deployment and Upgrade
The real-time update requirement for merchant basic information requires configuring low-latency API connection parameters during deployment, to avoid data sync delays affecting accurate matching of marketing materials. The hourly sync requirement for foot traffic data requires retaining temporary cache nodes during upgrades, to prevent missing material delivery data due to sync interruptions. Diverse marketing material formats and large individual file sizes require compatibility with newly added parsing plugins during upgrades, to avoid failure to index some poster and short video materials. Scenarios with internal network connections to merchant systems require configuring security group whitelists during deployment, and not modifying existing network policies during upgrades, to prevent data sync interruptions caused by failed connections.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SYNC_API_INTERVAL | 30–60 seconds | Matches the real-time update requirement for merchant basic information, balancing data latency and server resource usage |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to long-duration parsing of marketing materials such as large leasing brochures and campaign promotional videos |
RECALL_RANGE_HOURS | 72 hours | Covers hourly-synced foot traffic data and delivery effect data for recent marketing campaigns |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports uploads of common commercial property marketing materials such as large posters and multi-page campaign brochures |
AUTO_UPGRADE_ENABLED | false | Prevents interrupting internal network-connected merchant system services during upgrades; manual upgrades are required after compatibility verification in advance |
DB_CONNECTION_RETRY_TIMES | 5 times | Addresses occasional MongoDB connection interruptions, improving connection stability after deployment |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material formats, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- After upgrading to version 4.10.1, the front-end interface displays version 4.10.0, meaning the front-end version number does not match the actual deployed version. The cause is that front-end static resource cache was not cleared during upgrade, resulting in old version resources not being replaced.
- After Docker deployment, the MongoDB connection works normally initially but later throws errors. The database connection logs show
connection refusedortimeouterrors. The cause is that automatic reconnection parameters after container restart were not configured, or internal network firewall rules were temporarily changed to block connections. - An
Error response from daemon: error from registrerror occurs when upgrading 4.9.10 fix2, meaning image pulling or container startup fails. The cause is incorrect image repository address configuration, or conflicting image versions in the local Docker cache.
How to Verify Proper Configuration
- View API sync logs to confirm that data sync frequency matches the configured
SYNC_API_INTERVAL, with no abnormal delays. - Upload marketing materials in formats commonly used by commercial properties to confirm that parsing tasks complete normally, with no timeout errors.
- Run the manual upgrade process to verify that the front-end interface displays a version matching the deployment package version.
- Simulate a database connection interruption scenario to confirm that the service triggers the configured retry logic, and that the service operates normally after connection is restored.
