What the data for this category looks like
Data sources for auto service financing daily reports include financing application ledgers from auto dealers, loan disbursement records from partner financial institutions, and vehicle mortgage registration filing data. Data is updated via daily batch synchronization of full daily business data from the previous day, triggered in the early morning. Each daily report document uses a structured table format, with core fields including financing entity name, financing amount, loan disbursement date, repayment term, mortgaged vehicle VIN code, and approval status. Some entries include a remark field for supplementary explanations.
What constraints these characteristics impose on deployment and upgrade
The daily batch synchronization of full data requires configuring the scheduled task trigger frequency to match the data update rhythm, to avoid repeated pulls or missed time-period data. The fixed fields of the structured table require enabling structured extraction mode during knowledge base parsing, and presetting field mapping rules to avoid retrieval exceptions caused by non-standardized fields. The long-text remark field attached to some entries will occupy a large amount of context quota. During upgrades, adjust the context parameter threshold to adapt to content length. The VIN code as a unique identifier field requires configuring precise matching recall rules during deployment, to avoid associating incorrect financing entries. After upgrading low-version systems, re-verify the field mapping relationship to avoid field binding failure caused by version iteration.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | When a single auto service financing daily report document includes remark fields, it can occupy a large amount of context space. Sufficient space must be reserved to accommodate complete parsed content |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Structured table parsing requires batch processing multiple sets of field mappings. The timeout period must cover the full batch parsing process |
UPLOAD_FILE_MAX_SIZE | 200 MB | A single batch-synchronized daily report compressed package may reach a large volume. Sufficient upload space must be reserved |
Recall Count | Top 8–10 entries | Core entries of financing daily reports require precise matching. Excessive recall will interfere with context organization and question answering generation |
Similarity Threshold | 0.85–0.9 | The VIN code is a unique identifier field. A high similarity threshold is required to avoid mismatching non-corresponding financing entities |
Scheduled Task Trigger Interval | Daily 02:00 | The data synchronization rhythm generates the previous day's data in the early morning daily. The trigger interval must match the business update cycle |
The parameter values provided on this page are all conventional recommendations used as a starting point for configuration. 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
- A
502 Bad Gatewayerror is returned during source code local deployment, and the system log shows "structured parsing timed out". The cause is failure to adjust thePARSE_FILE_TIMEOUT_SECONDSparameter. The default timeout duration is insufficient to complete full field parsing of batch daily reports. - The
maxContextparameter is set to 10000 characters during deployment, but the backend configuration page shows 4000 characters, resulting in content truncation in final question answering results. The cause is that the parameter value configured in the backend takes priority during model calls, and the global settings set during deployment are not prioritized. - After upgrading the commercial version, all field mappings of existing knowledge bases become invalid, and retrieval results are empty. The cause is failure to perform the knowledge base initialization process during the upgrade, and the new version cannot load the field binding configuration from the old version.
How to confirm configurations are complete
- Upload a test auto service financing daily report document, and check whether the parsed fields match the preset mapping rules.
- Trigger a manual synchronization task, and check whether the synchronization log shows that data pulling and parsing are completed without abnormal errors.
- Enter a specific VIN code to initiate a retrieval, and verify the field integrity and matching accuracy of the returned results.
- Enter the backend configuration page, and check whether the values of core parameters match the preset configurations.
