Deployment and Upgrade for Carbon Steel Yield Reporting

Data Structure for This Category

Domestic steel industry professional information platforms, futures delivery warehouse inventory records, and spot trade transaction ledgers provide carbon steel market and yield data. These sources release the data as a daily full-category report document after 16:30 each day on a fixed schedule. Each document includes fields such as transaction date, steel product type, specification model, origin, spot transaction price, yield, daily trading volume, total social inventory, and additional related fields. The unit for spot transaction price is yuan/ton, trading volume is tons, and total social inventory is ten thousand tons.

Deployment and Upgrade Constraints

The multi-product, multi-specification nature of the carbon steel category requires configuring data source grouping and synchronization rules by product category during deployment, to avoid field mapping confusion. The fixed 16:30 daily update schedule requires configuring precise scheduled trigger parameters during deployment. Upgrades must avoid this time window to prevent interruptions to the daily report generation process. The need for cross-data-source spot and futures linked calculations requires configuring cross-database association retrieval thresholds, to ensure the accuracy of yield calculations. The requirement for consistent units across multiple fields requires configuring unit validation rules during the parsing phase, to prevent abnormal units from being included in data.

Configuration ItemRecommended SettingRationale
SYNC_CRON_EXPRESSION0 30 16 * * ?Matches the 16:30 daily update schedule for carbon steel daily reports, ensuring scheduled synchronization tasks trigger on time
PARSE_FIELD_MAPPINGConfigured based on actual testingCarbon steel data includes multi-dimensional fields such as product type, specification, and origin. Custom mapping rules are required to adapt to different data source formats
VECTOR_SPLIT_CHUNK_SIZE800-1200 charactersCarbon steel daily report single records have many fields. This length ensures a single data chunk contains complete product and market information
RECALL_TOP_KTop 8 entriesCarbon steel has many popular product types. This recall count covers core categories while avoiding redundant results
UPLOAD_FILE_MAX_SIZE500 MBSingle full-category carbon steel daily report documents typically do not exceed 300 MB. This setting reserves reasonable redundant space
MCP_ENABLEDEnabledCross-data-source linked yield calculations are required. FastGPT version 4.8.17 or higher is recommended to enable this functionality

The parameter values provided on this page are standard recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Each scenario requires individual analysis. It is recommended to test on your own samples before finalizing settings.

Common Misconfigurations

  • Symptom: Accessing the deployed market report service returns 405 Method Not Allowed. Cause: FastGPT API gateway routing rules allowing POST requests are not configured, or port mapping only allows GET requests.
  • Symptom: Team management functionality cannot be enabled in local deployments. Cause: The TEAM_MANAGEMENT_ENABLED configuration item is not set to true, and the service has not been restarted to load the latest configuration.
  • Symptom: Some nodes cannot access the latest carbon steel daily report data after multi-node deployment. Cause: A shared storage volume for mounting the daily report document directory is not configured, resulting in data desynchronization between nodes.

How to Verify Proper Configuration

  • Review scheduled task logs to confirm that carbon steel daily report synchronization and parsing tasks trigger at 16:30 each day. Compare the task execution time in the logs against the configured SYNC_CRON_EXPRESSION to confirm consistency.
  • Upload a test carbon steel daily report document. Check that the parsed result fields match the preset PARSE_FIELD_MAPPING rules, and confirm that all required fields are correctly extracted.
  • Submit a market report query request. Verify that the number of returned results matches the RECALL_TOP_K configuration, and that the query includes yield data for target carbon steel product types.
  • Check the shared storage directory for multi-node deployments. Confirm that all nodes can access the latest daily report documents, and that configuration items are not reset after service restarts.
