What the data for this category looks like
Data sources are public market APIs and official disclosure documents from licensed financial information service institutions. The update schedule follows: full daily target data is crawled after market close each day, and daily report content is consolidated and verified in the early morning of the next day, ensuring only one complete daily report is released per day.
Document structure uses a single structured record, including asset category, unique asset identifier, full asset name, statistical cycle, revenue value, reference benchmark identifier, and data traceability identifier. A complete daily report document contains 50 to 200 target records, with fields unique asset identifier, statistical date, revenue value, and reference benchmark. The unit of revenue value is a standardized non-percentage financial measurement unit. All records include clear statistical cycle and data traceability information to avoid revenue data without a valid source.
What constraints these characteristics impose on deployment and upgrade
Data dependence on third-party APIs requires configuring valid API access permissions and keys during deployment, and presetting field verification rules to avoid parsing failures caused by API changes. The fixed daily update schedule requires configuring precise scheduled trigger tasks, with trigger times later than the regular update window of third-party data sources to ensure complete daily data is obtained.
The characteristic that a single document contains a large number of target records requires configuring reasonable batch processing thresholds to avoid single-processing timeouts. During the upgrade phase, if a third-party data source adjusts field names or structure, field mapping rules need to be updated quickly, so a configurable field mapping module must be reserved during deployment to avoid hard-coded parsing logic.
For daily reports in the education service scenario, data traceability accuracy must be ensured. A data verification link must be configured during deployment to perform validity checks on the data traceability identifier field, avoiding content from non-compliant data sources.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
CRON_EXPRESSION | 0 30 1 * * * | Third-party data sources typically complete daily data updates before 23:00 local time. Triggering at 01:30 ensures complete daily data is obtained |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single daily report document contains a large number of target records, resulting in long parsing times. 600 seconds covers parsing requirements for most scenarios |
MAX_BATCH_PROCESS_COUNT | 100 records/batch | A single document contains 50 to 200 target records. Batch processing avoids single-request timeouts |
FIELD_MAPPING_RULE | Configure according to the data source's return structure | Map fields returned by third-party APIs to the platform's preset broadcast fields to ensure correct content generation logic |
UPLOAD_FILE_MAX_SIZE | 800 MB | The storage size of a single structured daily report document typically does not exceed 400 MB. Setting a reasonable upper limit avoids upload failures |
NOTIFICATION_WEBHOOK | Configure internal operation notification address | Send notifications when the daily report is generated or an exception occurs, enabling timely handling of abnormal situations |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require on-site analysis. Testing on local samples is recommended before finalizing settings.
Three common deployment mistakes
- Symptom: The
v4.8.15-fix2version of the Docker image is used during deployment. An "image not found" error is returned after executing the pull command. Cause: This version is a temporary fix release and was not synchronized to the publicly accessible directory of the official image repository. - Symptom: After configuring a login-free sharing link for an overseas deployment version, a
403 Forbiddenstatus code is returned when accessing. Cause: Cross-origin access whitelist for overseas nodes and valid duration of the login-free token were not configured correctly. - Symptom: Duplicate target records and news snippets appear in the generated daily report content. Cause: Deduplication verification rules for batch processing were not enabled, resulting in duplicate data from the same data source being parsed multiple times and included in the final content.
How to confirm successful configuration
- Manually trigger the scheduled task, verify that the task execution time matches the
CRON_EXPRESSIONconfiguration, and confirm that the task successfully pulls data from the data source. - Upload a test structured daily report document, check whether the parsed fields match the preset mapping rules, and confirm that field extraction is normal.
- Access the configured login-free sharing link, check whether the page loads normally and content is displayed correctly, and confirm that cross-domain and token configurations meet the current deployment environment requirements.
- View system operation logs, check for abnormal errors in data parsing or API calls, and confirm that the configured verification rules are in effect.
