What the data for this use case looks like
Data for city commercial bank research report retrieval comes primarily from two sources: regional finance and inclusive finance documents produced by the bank’s research department, and city commercial bank niche track research reports provided by cooperating third-party institutions. Update cadence follows two schedules: weekly updates for key track documents, and monthly updates for full industry overviews. Most documents are in PDF format, and contain title, publishing institution, publish date, core business data, and countermeasures and suggestions. Available fields include document ID, title, publish time, content summary, and associated business segments. Common units used are billion yuan and ten thousand households.
Constraints on HTTP Interfaces and External Systems
Multiple data sources require interfaces to support authentication rules that distinguish between internal and external documents, and adapt to certificate-based authentication methods commonly used in internal bank systems. Differentiated update cadences require scheduled synchronization tasks for interfaces to support custom cycles, and provide incremental synchronization capabilities to avoid excessive internal system resource usage from full synchronization. PDF document structure requires interfaces to support long-text parsing parameters, and enable segmented processing to prevent timeouts. Associated business segments and publish time fields require interfaces to provide corresponding filter parameters, to meet targeted retrieval needs of internal business systems.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SYNC_CRON_EXPRESSION | 0 0 2 * * 1,4 | Matches incremental synchronization schedule for 2:00 every Monday and Thursday, aligns with key track document update frequency |
PARSE_PDF_MAX_PAGE | 500 | Adapts to typical page counts of city commercial bank research reports, avoids parsing timeouts |
SEARCH_FILTER_FIELDS | ["publish_time","business_tag"] | Matches core filter fields for city commercial bank research reports, supports targeted retrieval for internal business systems |
API_AUTH_TYPE | certificate | Adapts to certificate-based authentication methods commonly used in internal bank systems, replaces generic API keys |
UPLOAD_FILE_TIMEOUT | 300 seconds | Adapts to parsing time for long PDF documents, prevents synchronization task interruptions |
RECALL_TOP_K | Top 20 entries | Matches retrieval volume requirements for city commercial bank research reports, avoids returning excessive redundant data |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, 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 Misconfigurations
- An HTTP interface call returns a 401 unauthorized error. Cause: Certificate authentication adapted for internal bank systems is not configured, and generic API key authentication is used instead.
- Conversation records are not written to the database after the client closes the SSE connection. Cause:
API_REQUEST_TIMEOUTis not set to a reasonable duration, so the interface does not trigger asynchronous database persistence logic after SSE interruption. - Reordering effects for retrieval results do not take effect. Cause: The correct reranking API address is not configured in
RERANK_API_CONFIG, or the reranking switch is not enabled.
How to Verify Successful Configuration
- Call the data synchronization interface, and check if the return logs include synchronization success markers for internal and external data sources.
- Pass the
publish_timeandbusiness_tagparameters to initiate a retrieval request, and verify that returned results match the filter rules. - Configure the reranking API address and enable the corresponding switch, then initiate a retrieval request to verify that the returned result sorting logic takes effect.
- Close the SSE connection, then check if corresponding conversation records are generated in the database.
