What the data for this category looks like
Data sources related to consumer electronics profit yield include industry supply chain monitoring platforms, e-commerce platform sales snapshots, and brand-published official retail documents. Update frequency falls into three categories: online channel data is updated daily, offline retail data is updated weekly, and cross-regional aggregated data is updated monthly. Documents are in structured CSV or JSON format, with each record corresponding to a single SKU. Fields include SKU code, product model, sales channel, per-unit procurement cost (yuan), per-unit terminal selling price (yuan), monthly shipment volume (units), and region code field, with no nested levels.
What constraints these characteristics impose on model integration and configuration
Multiple update frequency data sources require configuring differentiated synchronization trigger cycles, distinguishing task schedules for daily online updates, weekly offline updates, and monthly aggregated updates. Structured fields with no nesting and wide category coverage require configuring field mapping rules to prevent the model from confusing SKU codes with other identification fields during reading. Format differences across data sources require configuring unified standardization conversion logic to align fields such as SKU codes and price units across different platforms. A large number of SKUs for a single category and wide numerical range require configuring field filtering rules for vector retrieval, only recalling core field data related to profit yield calculation.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DATA_SYNC_CRON | Set to 0 0 * * * for online data, 0 0 * * 0 for offline data | Matches the daily and weekly update rhythms of the corresponding data sources |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Structured documents with multiple SKUs take longer to parse, prevents mid-process timeout interruptions |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Cross-regional aggregated monthly data files have large sizes, adapts to bulk upload requirements |
parseChunkSize | 800–1200 characters | Single SKU data has moderate length; overly long segments increase retrieval load, overly short segments split complete data |
vectorRecallTopN | Top 8–12 entries | Consumer electronics has a large number of SKU categories; limiting the recall range avoids redundant data interfering with calculations |
similarityThreshold | 0.75–0.85 | Structured field matching requires high precision, filters recall results for irrelevant SKUs |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- A
model not founderror occurs when configuring a local large model, and the specified model fails to load. The cause is incorrect configuration of the model loading path and system environment variables, and failure to place the model file in the FastGPT preset model directory. - Retrieval results only return preset QA content, and SKU-related profit yield data is not recalled. The cause is failure to configure field recall rules for the structured knowledge base, with only the retrieval logic of the preset question answering library enabled.
- Data synchronization tasks frequently time out, with the task status showing
timeout. The cause is failure to adjust thePARSE_FILE_TIMEOUT_SECONDSparameter, using the default short timeout setting that cannot adapt to the parsing time of multi-SKU documents.
How to confirm the configuration is complete
- Enter the model testing interface, input the profit yield calculation requirement for a single SKU, and verify that the returned result includes core fields consistent with the configured structured fields.
- View the data synchronization task log, confirm that the synchronization trigger times for online and offline data sources match the configured
DATA_SYNC_CRONexpression. - Initiate a vector retrieval test, verify that the number of recalled results matches the configured
vectorRecallTopNvalue, and the similarity falls within the preset range. - Upload a single test structured document, confirm that the parsed field order matches the configured mapping rules.
