What data for this category looks like
This category’s data comes from steel coil labels and quality certificates, press and feeder operating data, mold management systems, MES systems, coordinate measuring machine or fixture inspection data. Daily documents include stamping work instructions, material utilization rate sheets, mold inspection sheets, first and last piece records, dimensional inspection reports, and mold change records. Updates trigger per coil, per batch of material, or each mold change. Document fields include material grade, stamping pressure, mold number, inspection dimensions, mold change time, and other items, with corresponding units such as millimeters, megapascals, hours, and others.
What constraints these characteristics impose on deployment and upgrade
This category’s multi-source heterogeneous data and high-frequency update rhythm require deployments to use connection configurations adapted to multi-system data access, to avoid synchronization interruptions from unstable data sources. Frequent coil, batch, and mold change updates require incremental synchronization mechanisms to cut resource usage from full synchronization. Diverse business documents and differentiated fields require upgrades to retain compatible configurations for original document parsing rules, to prevent historical data parsing failures during version updates. The strong correlation between inspection data and production parameters requires deployments to complete data link configuration, to ensure complete associated information is available for audit processes.
How to set the configuration
This configuration description is adapted for FastGPT v4.17.0 version
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://admin:securepass@mongodb-host:27017/fastgpt?authSource=admin | Adapts to the storage needs of multi-source production data in stamping workshops, supports high-frequency read and write operations |
REDIS_URL | redis://:redispass@redis-host:6379/1 | Used to cache frequently accessed mold inspection and first and last piece record data, reducing database load |
STORAGE_S3_ENDPOINT | https://s3-internal.company-domain.com | Stores large-volume business documents such as dimensional inspection reports and mold change records |
DB_MAX_LINK | 20–30 | Matches the concurrency of data updates in stamping workshops, avoids synchronization failures caused by exhausted connection pools |
FILE_TOKEN_KEY | Randomly generated 32-bit encrypted string | Used to generate secure access links for business documents, preventing unauthorized access |
Three common mistakes
- Phenomenon: After an upgrade, the front-end page displays a version number that does not match the actual deployed version, and the knowledge base list fails to load normally. Cause: Front-end static resource cache was not cleared during the upgrade, so old version resources are still being called.
- Phenomenon: The model stream response returned when calling the inspection data audit tool is empty. Cause:
REDIS_URLwas not configured correctly during deployment, causing cached context data to fail to read normally, interrupting the tool call link. - Phenomenon: Database connection timeout errors occur when batch importing mold change records. Cause:
DB_MAX_LINKconfiguration was not adjusted, and concurrent import requests exceed the database connection pool limit, making it impossible to establish new connections.
How to confirm the configuration is correct
- Run the container log viewing command to confirm that the
MONGODB_URIandREDIS_URLconfigurations can establish normal connections, with no error logs. - Upload a stamping work instruction, verify that the parsed document can be normally retrieved and viewed in the knowledge base, and confirm that the
STORAGE_S3_ENDPOINTandFILE_TOKEN_KEYconfigurations are valid. - Simulate an incremental synchronization operation for mold change data, check whether the data is normally written to the database, and confirm that the
DB_MAX_LINKconfiguration matches the concurrency requirements. - Access the front-end page corresponding to the configured
FE_DOMAIN, verify that the system version number matches the deployment package version, and confirm that the front-end resources have been correctly updated.
