What the data for this category looks like
Data sources include breeding ledgers of aquaculture entities, statistical data from regional fishery associations, and financing application records from cooperative financial institutions. Full update of the previous workday’s data is completed daily between 02:00 and 04:00. Each document corresponds to a single breeding entity, and includes fields such as entity ID, breeding category, breeding scale (unit: mu), total inventory (unit: kg), daily feed purchase volume (unit: ton), daily financing application amount (unit: ten thousand yuan), daily credit approval amount (unit: ten thousand yuan), and regional average acquisition price (unit: yuan/kg). Word count parameters for single documents vary widely. It is recommended to confirm values based on sample statistics or actual measurement tailored to the specific deployment.
What constraints these characteristics impose on model access and configuration
Fixed daily update schedules require scheduled synchronization tasks to use execution times that avoid the update window, preventing data conflicts. Multiple fields with clear units require strict binding of unit identifiers during field mapping, preventing the model from confusing measurement rules across different categories. Moderate single-document word count requires adjusting the context window configuration, avoiding truncation of critical financing information. Multi-data source fusion requires configuring cross-source data verification rules, ensuring matching consistency of entity IDs between breeding data and financing data, and improving retrieval accuracy.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SYNC_CRON_EXPRESSION | 0 5 * * * | Avoids the daily 02:00-04:00 data update window, ensuring synchronization of complete previous workday data |
maxContext | 1200-1800 characters | Single document word count falls between 300-800 characters; this range can hold complete content for 3 to 5 retrieved documents |
RECALL_TOP_K | Top 6 entries | Financing-related information needs to cover three core dimensions: breeding entity, acquisition price, and financing application; 6 entries provide sufficient associated information |
FIELD_MAPPING_STRICT_MODE | Enabled | Fields include clear units such as mu, kg, ten thousand yuan; strict mode prevents the model from confusing different measurement dimensions |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Multi-data source fused document parsing requires a longer timeout period, to avoid parsing timeout failures for small-volume data |
LOCAL_MODEL_API_ADDR | http://localhost:11434/v1 | Adapts to the standard API path for locally deployed large models, matching local access configuration requirements |
The parameter values provided on this page are all common recommended 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 confirm after actual testing on samples tailored to the specific deployment.
Three common configuration mistakes
- Symptom: Connection timeout or
500 Internal Server Erroroccurs when configuringLOCAL_MODEL_API_ADDRafter deploying a local large model. Cause: The standard API path of the local large model is not matched, such as incorrectly changing the port number or omitting the/v1interface suffix. - Symptom: Field units in knowledge base retrieval results are mixed, for example, "mu" for breeding area is displayed as "kg". Cause:
FIELD_MAPPING_STRICT_MODEis not enabled, and the mapping relationship between fields and units is not strictly bound. - Symptom: Data is not updated after a scheduled synchronization task runs, or a
400 Bad Requesterror is returned. Cause: The execution time set bySYNC_CRON_EXPRESSIONoverlaps with the data update window, leading to synchronization of incomplete temporary data.
How to confirm the configuration is complete
- Run a manual synchronization task, and check that the number of documents in the synchronization log matches the number of entries in the preset breeding entity list.
- Initiate a test query, and verify that the returned result fields include correct unit identifiers, for example, the breeding scale field displays a value with its corresponding unit.
- Check the model call log, and confirm that the API request address matches the configured
LOCAL_MODEL_API_ADDR, with no connection failure records. - Check the scheduled synchronization task execution log, and confirm that the task completed execution during the preset non-update window period.
