What this category of data looks like
The data sources for tax-free financing daily reports include offshore tax-free merchant financing application systems, local customs supervision declaration platforms, and payment clearing interfaces. Data is updated by syncing full business data from the previous calendar day in batches every early morning. Each daily report document is formatted as structured CSV or JSON, and includes fields such as merchant unified social credit code, tax-free business category, daily financing application amount, available credit balance, repayment period, and supervision declaration number. Field units are RMB yuan and calendar days, with no extra nested levels. Data only covers content related to the same day, with no historical cumulative data. The typical size of a single document is no more than 10 MB.
What constraints these characteristics impose on deployment and upgrade
The fixed daily update schedule requires configuring scheduled pull tasks aligned with the sync window to avoid conflicts with early morning business data synchronization. Structured documents with exclusive supervision fields require enabling structured data validation rules to check the format of fields such as unified social credit code and supervision declaration number, preventing invalid data imports. Multi-data source access needs permission isolation for multiple API keys to avoid leakage of single data source permissions. During upgrade, retain the running status of original scheduled tasks to avoid interrupting daily data sync processes. This requires using a gray release strategy, with phased restart of service nodes. Pre-configure sensitive field desensitization settings to prevent compliance risks.
Configuration Settings
| Configuration Item | Recommended Value | Basis for This Setting |
|---|---|---|
CRON_SCHEDULE | 0 1 * * * | Matches the daily 1 AM data sync window to avoid conflicts with business peak hours |
PARSE_FILE_TIMEOUT_SECONDS | 60 seconds | Structured data parsing requires no complex OCR or typesetting processing; 60 seconds is sufficient for format validation and field extraction |
UPLOAD_FILE_MAX_SIZE | 50 MB | Single structured daily report document typically does not exceed 10 MB, with reasonable buffer space reserved |
SCHEMA_VALIDATION_ENABLE | Enabled | Tax-free financing daily reports include exclusive supervision fields, so format compliance of fields such as unified social credit code and declaration number must be verified |
RECALL_TOP_K | Top 3 entries | Key business fields of structured data are concentrated; only a small number of recalls are needed to cover business query needs |
DATA_MASKING_RULES | Desensitize the last 4 digits of merchant name and unified social credit code | Involves merchant sensitive information, must comply with data compliance requirements |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: Scheduled pull task shows no data sync, with logs returning
401 Unauthorizederror. Cause: Multi-data source API key permissions are not configured correctly, making access to customs supervision platform or merchant financing system interfaces impossible. - Phenomenon: Key business fields are empty after an uploaded daily report document is parsed. Cause: The
SCHEMA_VALIDATION_ENABLEconfiguration is not enabled, and field format verification is not performed. Non-standard documents are imported without identifying valid fields. - Phenomenon: Knowledge base configuration fails to load after service starts. Cause: An outdated open-source version image is used, and the latest image package of the corresponding version has not been pulled, causing configuration item parsing exceptions.
How to Confirm the Configuration Is Correct
- Manually trigger a scheduled pull task, check if the task log shows data sync success, and verify if the returned fields include the preset supervision declaration number.
- Upload a standard-format tax-free financing daily report document, check if the knowledge base parsing result extracts all preset fields completely, with no missing or abnormal values.
- Initiate a knowledge base query, check if the number of returned recall results matches the value set in the
RECALL_TOP_Kconfiguration. - Check if the service node's desensitization configuration takes effect, and verify if the exported test data has performed corresponding desensitization processing on merchant names and unified social credit codes.
