What the data for this category looks like
Data sources for chemical fiber financing daily reports include chemical fiber industry spot trading databases, upstream petrochemical raw material supply and sales ledgers, and regional dealer price summaries. Full data from the previous day is updated every early morning. Each daily report entry includes product identifier, daily transaction average price, daily shipment volume, upstream raw material CIF price, regional price difference range, and inventory turnover reference value. Unit specifications: Yuan/ton for transaction average price and raw material price, ton for shipment volume, days for turnover reference value. Data fields cover three core dimensions: upstream raw materials, spot trading, and regional price differences. Single entries have many associated fields.
What constraints these characteristics impose on deployment and upgrade
Multi-source data synchronization requirements impose timeout configuration constraints. Adjust configurations to accommodate differences in response times across data sources. Daily full data update frequency imposes vector database insertion load constraints. Control per-batch data volume to avoid overloading the database. Multi-dimensional associated field structures impose constraints on model embedding and retrieval. Calibrate field weights to align with business logic. High field standardization imposes Text2SQL mapping constraints. Directly match business database table structures without additional conversion. During upgrades, retain compatible configurations for original field calculation logic. Prevent new model versions from breaking existing data mapping relationships.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_DATA_SOURCE_TIMEOUT | 300 seconds | Aligns with the average time required for multi-source data synchronization of chemical fiber financing daily reports, prevents synchronization interruptions caused by short timeouts |
VECTOR_INSERT_BATCH_SIZE | 200–300 entries | Balances per-batch data processing efficiency and database load, matches the per-batch data scale of chemical fiber daily reports |
EMBEDDING_MODEL_NAME | ali-emb3 | Supports semantic embedding for chemical fiber industry category and price fields, meets retrieval requirements for specialized scenarios |
MAX_RECALL_DOCS | top 8 entries | Covers multi-dimensional associated information of chemical fiber financing daily reports, ensures business completeness of retrieval results |
TEXT2SQL_TABLE_MAPPING | directly map daily report field names to corresponding business database tables | Aligns with the standardized naming rules of chemical fiber daily report fields, reduces conversion errors in SQL generation |
HTTPS_ENABLED | enabled | Meets internal data transmission security requirements for private deployments, avoids risks from plaintext transmission |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After configuring
EMBEDDING_MODEL_NAMEasqwen3, the model configuration interface displays an error stating that this model only supports streaming inference. Cause: The local deployment version of qwen3 does not have non-streaming inference adaptation enabled, and streaming mandatory verification is not disabled in startup parameters. - Phenomenon: After Docker deployment, the access address still uses the HTTP protocol. Cause: The
HTTPS_ENABLEDconfiguration item is not enabled, and the SSL certificate file is not mounted to the specified deployment directory. - Phenomenon: The SQL statement generated by Text2SQL cannot query the corresponding data for chemical fiber financing daily reports. Cause: The
TEXT2SQL_TABLE_MAPPINGitem is not configured, the default table mapping rules are used directly, and the exclusive field naming of chemical fiber daily reports is not adapted.
How to confirm the configuration is valid
- Enter the data source management page, trigger a manual synchronization task, and check that there are no timeout errors in the synchronization log to confirm that the data synchronization configuration is effective.
- Access the deployed access address, check that the protocol identifier in the browser address bar is HTTPS to confirm that the secure transmission configuration is correct.
- Submit a test query containing chemical fiber category keywords, and check that the number of returned result entries matches the configured value of
MAX_RECALL_DOCS. - Run a test Text2SQL query statement to verify that the generated SQL correctly matches the business fields of chemical fiber daily reports and returns valid data.
