What the data for this category looks like
Data sources for water treatment financing daily reports include project record announcements from local ecological environment departments, public financing announcements from water utility enterprises, and record information from local financial supervision platforms. The update frequency is daily. It discloses information about water treatment-related financing projects completed on the same day. Each document contains fields such as project unique ID, water treatment project name, affiliated administrative region, financing amount, financing method, and information disclosure date. Financing amount units are primarily ten thousand yuan or hundred million yuan. The date format follows YYYY-MM-DD.
Constraints imposed by these characteristics on deployment and upgrade
The daily update requirement mandates configuring a fixed-frequency incremental sync task during deployment. This prevents full data pulls from consuming excessive system resources. There are unit differences in the financing amount field. Add unit standardization preprocessing logic during deployment to ensure unified data storage. The project ID serves as the unique identifier. Create a unique index in the database to avoid duplicate data being stored. If new fields are added during an upgrade, implement automatic completion logic for legacy version data. This prevents failed imports of old data. Additionally, daily new data source files have large file sizes. Reserve sufficient storage and parsing resources during deployment to avoid parsing timeouts.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGO_VERSION | 6.0.x | The official deployment script is compatible with this version, avoiding compatibility issues between MongoDB 7.0 and driver versions |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Batch data source files for water treatment financing daily reports typically do not exceed 1500 MB, reserving adequate upload space |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Batch parsing large data source files requires extended processing time, preventing premature timeout interruptions |
DAILY_SYNC_INTERVAL | 86400 seconds | Financing daily reports are updated daily, so the sync interval matches the data update cycle |
THIRD_PARTY_API_CONFIG | Configure according to the authentication method of the data source interface, such as API_KEY bound to request headers | Most government-affiliated financing data sources require authentication to secure data pull permissions |
VERSION_UPGRADE_MODE | Incremental upgrade | Retain existing database data during cross-version upgrades, avoiding full reset of business configurations |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Issue: Empty fields appear in pulled financing data after deployment. Cause: Third-party API authentication parameters were not configured correctly, resulting in incomplete access to data source field information.
- Issue:
MongoDB connection timeouterror occurs during upgrade. Cause: MongoDB 7.0 version was used, which is incompatible with the driver version of the current deployment script, causing connection abnormalities. - Issue:
413 Request Entity Too Largeerror is triggered when uploading knowledge base files in batches. Cause: TheUPLOAD_FILE_MAX_SIZEparameter was not adjusted, and the uploaded file exceeds the system default limit.
How to Verify Proper Configuration
- Manually trigger a data pull task. Check if the pulled data source fields include preset items such as project name and financing amount. Verify that field units meet expected standards.
- View MongoDB connection logs to confirm normal connection status, with no version compatibility-related errors.
- Upload a test water treatment financing daily report data source file. Check that parsing progress is normal, with no timeout errors.
- Run an incremental upgrade script. Confirm that existing business data is retained, and new configuration items take effect as expected.
