What the data for this category looks like
Chemical raw material financing daily reports pull data from three sources: weekly financing filing data publicly disclosed by domestic basic chemical industry associations, desensitized corporate credit ledgers from commercial banks, and financing inquiry records from commodity spot markets. Data updates follow a fixed weekly schedule. Full synchronization is completed by 15:00 every Wednesday. Each daily report uses CSV format, with 12 fixed fields. These fields include raw material name, unified social credit code, financing amount, financing term, credit granting bank, fund usage, filing date, and additional standard fields. Financing amount is denominated in ten thousand yuan. Financing term is measured in natural days. Some fields such as fund usage allow empty values.
Constraints on Deployment and Upgrade from Data Characteristics
The data traits of chemical raw material financing daily reports impose clear constraints on deployment and upgrade workflows. Configure cross-platform permission adaptation rules for multi-source heterogeneous data sources. This ensures simultaneous retrieval of industry association public data and bank desensitized corporate ledgers. Align timed scheduling tasks precisely to the 15:00 Wednesday synchronization window. This matches the fixed weekly update schedule, avoiding repeated data retrieval or delayed triggering. Set up field mapping and null value filtering rules during data parsing. This accommodates the 12 fixed fields and empty value compatible design, preventing empty fields from triggering errors in downstream processes. Adjust resource thresholds for upload and parsing based on individual daily report file sizes. Retain compatibility logic for legacy field mappings during upgrades. This prevents parsing failures for historical data during version iterations.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Individual daily reports can reach up to 150 MB. The parsing process completes multi-source data merging and field mapping. 1200 seconds covers the full parsing workflow |
SCHEDULE_CRON_EXPRESSION | 0 15 * * 3 | Matches the data release window completed by industry associations before 15:00 every Wednesday. This avoids synchronization delays or repeated data retrieval |
UPLOAD_FILE_MAX_SIZE | 200 MB | Individual daily reports have a maximum file size of 150 MB. 50 MB of redundant space is reserved to accommodate data growth |
FIELD_NULL_HANDLER_MODE | SKIP_AND_LOG | Some fields such as fund usage contain undisclosed empty values. Skipping empty values and recording logs prevents workflow interruptions |
DATA_SOURCE_WHITELIST | ["industry_association", "bank_credit"] | Only allows retrieval from configured legitimate data sources. This ensures data source security for financing daily reports |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfiguration Issues
- Symptom: Data parsing returns a
400 BAD REQUESTerror, with a large number of empty fields. Cause: TheFIELD_NULL_HANDLER_MODEparameter is not configured. Empty fields trigger mandatory validation rules, leading to workflow interruption. - Symptom: Scheduled tasks do not trigger data synchronization after 16:00 on Wednesday, with no execution records in scheduling logs. Cause: The
SCHEDULE_CRON_EXPRESSIONparameter is set to0 16 * * 3, which does not match the industry association's data preparation window. This causes synchronization delays. - Symptom: The password-free share link for overseas deployment versions displays a
503 SERVICE UNAVAILABLEerror when opened. Daily report data fails to load. Cause: Network timeout and file size parameters are not adjusted for overseas nodes. Insufficient overseas bandwidth causes large file upload timeouts.
How to Verify Successful Configuration
- Upload a single standard test CSV file of chemical raw material financing daily reports. Check if parsing logs generate execution records for field matching and null value handling.
- Manually trigger the configured timed scheduling task. Wait for synchronization to complete, then verify that the number of generated data entries matches the number of entries in the source file.
- Generate a password-free share link. Open it in the corresponding network environment to confirm that full daily report data loads correctly.
- Adjust the upload file size threshold to slightly exceed the size of the test file. Verify that large file upload and parsing workflows run without errors.
