What the data for this category looks like
Data sources for comprehensive service yield rate and daily market report data include exchange public market APIs, licensed financial data service provider APIs, and internal product operation systems. Data updates run once per trading day, with full updates completed 1 to 2 hours after market close. Documents use structured JSON or CSV formats. Each record includes standardized fields such as product unique identifier, data release date, yield benchmark value, benchmark asset code, and data verification mark. No custom extended fields are included. Numeric fields use native numeric formats exclusively, with no percentage or relative ratio identifiers.
What constraints these characteristics impose on deployment and upgrade
Compliance requirements for multi-data source access: configure data source whitelists during deployment to only allow authorized interface access, preventing unauthorized data from entering the system. The daily full update schedule requires precise scheduling of timed task trigger times during deployment, plus sufficient interface call timeout windows to avoid synchronization failures caused by high concurrent load on interfaces after market close. Standardized structured field requirements: configure field mapping rules during deployment to unify field naming across different data sources, preventing field missing during parsing. During upgrades, retain custom verification rule configurations to avoid overwriting existing compliance verification logic via version updates, which could allow erroneous data into the reporting workflow.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DATA_SYNC_INTERVAL | 86400 seconds | Matches the daily update cadence of daily report data, avoids frequent pulls that trigger interface rate limits |
DATA_SOURCE_WHITELIST | Exchange market APIs, licensed data service provider APIs | Complies with financial data access compliance requirements, only allows authorized data sources to connect |
PARSE_DATA_TIMEOUT | 300 seconds | Full daily report data parsing takes significant time, reserve sufficient timeout to avoid synchronization task interruptions |
VALIDATION_FIELD_REQUIRED | ["product_code", "publish_date", "yield_value"] | Enforce non-empty checks for core fields to ensure basic completeness of reporting content |
API_RATE_LIMIT | 10 requests per minute | Adapts to rate limit thresholds for most financial data interfaces, prevents interface bans |
UPGRADE_BACKUP_PATH | /data/fastgpt/backup/$(date +%Y%m%d) | Automatically backs deployment files by date, enables rapid rollback after upgrades |
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 Mistakes
- No log output for post-deployment timed synchronization tasks. The cause is failure to configure the
DATA_SYNC_LOG_PATHparameter, which prevents logs from being saved and makes synchronization exceptions impossible to troubleshoot. - Missing fields in reporting content after upgrades. The cause is failure to retain custom configurations for
VALIDATION_FIELD_REQUIREDduring upgrades, which overwrites preset core field verification rules. - 429 status code triggered during data pull. The cause is failure to set the
API_RATE_LIMITparameter, causing request frequency to exceed the rate limit threshold of financial data interfaces. This issue matches common interface call exception scenarios in the community.
How to Verify Correct Configuration
- Manually trigger a data synchronization task, check the log file corresponding to
DATA_SYNC_LOG_PATH, and confirm that synchronization success marker logs are present. - Call the built-in data source connectivity verification interface to verify that all interfaces in
DATA_SOURCE_WHITELISTcan return data normally. - Generate a single test report entry, check that all core fields are populated and meet preset format requirements.
- View system resource monitoring on the deployment node, confirm that synchronization tasks did not trigger timeout interruptions due to insufficient
PARSE_DATA_TIMEOUTconfiguration.
