Deployment and Upgrade for Consumer Building Materials

What the data for this category looks like

Data sources include local housing and construction department building material project registration databases, supply chain financial institution loan ledgers, and industry dealer financing submission data. Full synchronization of the previous day’s data is completed every early morning. The structure of each data entry includes these fields: project identifier, building material subcategory, financing subject name, financing amount, loan institution, loan date, and project location city. Financing amount is measured in ten thousand yuan. Date fields use ISO standard date format. Project identifiers are unique encoded strings.

What constraints these characteristics impose during deployment and upgrade

The multi-source data nature requires configuring multi-data source access adaptation rules during deployment to prevent parsing failures caused by format differences. The daily update frequency requires adjusting the trigger cycle of scheduled synchronization tasks during upgrade to ensure data timeliness. The presence of the building material subcategory field requires configuring classification recall rules to match query needs for different building material subcategories. The financing amount unit set to ten thousand yuan requires configuring unit conversion verification in the value parsing link to prevent amount deviations. The existence of unique project identifiers requires enabling knowledge base deduplication configuration to avoid duplicate data occupying storage space.

How to configure

Configuration Item	Recommended Value	Rationale
`SYNC_CRON`	`0 1 * * *`	Matches the update schedule of syncing previous day’s data every early morning, avoids occupying resources during business peak hours
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Parsing a single daily report document usually takes no more than 2 minutes; multi-source batch uploads require sufficient fault tolerance time
`Segment Length`	`800–1200 characters`	Consumer building materials financing daily reports have many short fields; segment length adapts to the combined text length of fields to avoid semantic fragmentation
`Similarity Threshold`	`0.75–0.85`	Distinguishes financing records of different building material subcategories, prevents irrelevant results from being included in recall lists
`Recall Count`	`Top 8 entries`	The data volume of a single daily report is moderate; 8 recall entries can cover all dimensions of project financing information
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Adapts to the size of monthly summary reports for batch imports, prevents upload failures

The parameter values provided on this page are conventional recommendations used as starting points for configuration. Actual values are affected by material form, 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 mistakes

Phenomenon: Request Timeout error appears during conversation, with status code 504. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter was not adjusted according to the parsing needs of consumer building materials financing daily reports; the default timeout period is too short, causing parsing to fail to complete.
Phenomenon: Irrelevant non-consumer building material category financing records are mixed into recall results. Cause: The Similarity Threshold was not set, or the threshold was set too low, failing to filter matching results from irrelevant categories.
Phenomenon: Scheduled synchronization tasks do not update data on time. Cause: The SYNC_CRON expression was configured incorrectly, failing to match the daily early morning synchronization update schedule, or the time zone setting was not verified to match the data source’s update time zone.

How to confirm correct configuration

Upload a single test consumer building materials financing daily report document, verify the field integrity of parsing results, and confirm all preset fields are correctly extracted.
Initiate a query containing consumer building material subcategories, verify that the number of recall results matches the configured Recall Count, and adjust the threshold to match the expected matching accuracy.
Manually trigger a scheduled synchronization task, check task logs to confirm data synchronization is completed without parsing errors, and verify the trigger logic of SYNC_CRON.
Upload a batch summary report, confirm upload progress is normal and the UPLOAD_FILE_MAX_SIZE limit is not triggered, and adjust parameters to adapt to batch import needs.
