Deployment and Upgrade for Home Goods Yield Rate Reporting

What the data for this category looks like

Home goods yield rate data comes primarily from three sources: public monitoring databases for the light manufacturing industry, brand inventory and sales ledgers, and sales settlement data from offline stores. Data is updated weekly or monthly; some soft furnishing subcategories update on a quarterly cadence. Each data document uses a structured table format, with each row corresponding to cycle sales data for a single SKU. Fields include SKU code, category name, unit cost, terminal selling price, cumulative cycle sales, market benchmark average price, and more. Unit cost and selling price use yuan as the unit. Yield rate-related fields use cumulative cycle values, and there is no real-time high-frequency market data.

What constraints these characteristics impose on deployment and upgrade

Home goods have a large number of SKUs and complex subcategories, and data updates are not real-time. Deployments must use incremental sync logic to reduce resource usage. Scheduled sync tasks must align with weekly or monthly update cadences, and must avoid business peak periods. During upgrades, if data source configurations are adjusted, ensure historical cycle data is not overwritten. Overwriting historical data will cause gaps in historical yield rate reports. Precise mapping of multiple fields requires pre-sorting the data structure during deployment to avoid field misalignment after parsing, which disrupts subsequent recall and reporting.

How to set configurations

Configuration Item	Recommended Setting	Rationale
`SYNC_CRON_EXPRESSION`	`0 0 2 * * 1`	Runs full sync at 2 AM every Monday, aligns with the weekly update cadence of home goods data and avoids business peaks
`DATA_SYNC_INCREMENTAL`	`true`	Home goods have a large number of SKUs; incremental sync avoids excessive server resource usage from full pulls, only syncs new or modified data within the update cycle
`PARSE_FIELD_MAPPING`	`Map by SKU code, category name, cycle yield rate fields`	Home goods data includes multiple SKU-specific subfields; precise mapping prevents missing or misaligned fields after parsing, ensuring normal subsequent data calls
`RECALL_TOP_K`	`Top 8–12 entries`	Home goods categories have many SKU subcategories; appropriate recall volume covers yield rate comparison needs for more sub-scenarios, avoiding excessive redundant data in recall results
`SIMILARITY_THRESHOLD`	`0.75–0.85`	Balances precise matching and recall coverage, prevents irrelevant SKU yield rate data from being included in final reporting results
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Home goods data documents may contain thousands of SKUs; allocates sufficient time for field parsing and vector database ingestion

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. Each scenario requires individual analysis, and it is recommended to test on your own samples before finalizing settings.

Three common mistakes

Symptom: A network error is displayed when running a data source sync task, with a 502 status code returned. Cause: Cross-origin access permissions for private data sources are not configured, so the FastGPT container cannot pull home goods sales data documents normally.
Symptom: All existing field mapping configurations become invalid after upgrading to version 4.9.0. Cause: Local configuration files were not backed up, the configuration storage path changed in the new version, and old configurations were not manually migrated.
Symptom: The application returns Cannot read properties of undefined (reading 'yieldRate') when invoked. Cause: PARSE_FIELD_MAPPING was not configured correctly during data parsing, so the yield rate field was not properly mapped to fields usable by the application.

How to confirm configurations are correct

Manually trigger a full sync task, then check the sync logs in the data source management page. Confirm there are no errors and new SKU data has been successfully stored in the database.
Open the application debugging interface, enter specific home goods category keywords, and verify that the recalled result fields fully match the configured PARSE_FIELD_MAPPING.
Temporarily adjust SIMILARITY_THRESHOLD to 0.9, confirm that only highly matched SKU yield rate data is returned, then restore the original threshold to ensure the recall range meets expectations.
Restart the FastGPT container, then check that the scheduled sync task still runs automatically according to the configured SYNC_CRON_EXPRESSION, with no abnormal startup errors.
