What the data for this category looks like
Data for this category comes from customer manuscripts, color management systems, printing press operation data, ink and substrate batch records, spectrometers, barcode detectors, and other equipment and systems. Daily business documents include pre-press files, imposition sheets, printing process sheets, ink color matching records, first article approval samples, barcode inspection reports, die-cutting and lamination records, and more. Data is updated frequently per order, batch, and plate change. It includes fields such as text and images, plate number information, color parameters, batch numbers, and inspection results. There are no unified fixed units. Values change dynamically based on individual business batches.
What constraints these characteristics impose during deployment and upgrade
Business data updates frequently per order, batch, and plate change. Deployment must adapt storage and connection configurations for high-frequency small-batch writes. This avoids service interruptions. Multiple types of structured and unstructured business documents coexist. Deployment must support multi-source data access and multi-format parsing. Printing misprints can be replicated rapidly to cause mass scrap. Deployment must add configuration items to strengthen data verification and recall accuracy. The platform must handle three types of business information: content, color, and packaging structure. The knowledge base must support multimodal data indexing. Upgrades must be compatible with newly added document parsing plug-ins. Version upgrades must also adapt to high-frequency updated data migration. This prevents loss of historical business data.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | Adapts to high-frequency updated printing order and inspection data, avoids database connection pool exhaustion |
MONGODB_URI | Fill in the full connection string according to local deployment cluster or cloud service instance | Stores multiple types of printing business documents and historical maintenance records |
REDIS_URL | Local or cloud-hosted Redis connection address using port 6379 | Caches frequently queried process parameters and device status data, reduces database load |
STORAGE_S3_ENDPOINT | Fill in the endpoint provided by the object storage service provider | Stores large-volume business documents such as pre-press files and first article approval samples |
FE_DOMAIN | Public network or internal network domain for deploying the service | Configures the frontend access address, ensures normal loading of the equipment inspection and maintenance Q&A interface |
Three common errors
- Symptom: Deployment fails on Windows Server 2022, with a prompt about port occupation or missing dependencies. Cause: Failure to adapt container runtime configuration for Windows systems, or failure to install the required runtime environment dependencies of the correct version.
- Symptom: Networking functionality cannot be enabled after deploying FastGPT v4.6.7, and Q&A results cannot obtain the latest device parameters. Cause: The older version does not have a built-in networking plug-in. External calling interface permissions must be configured manually, and environment variables are not modified correctly to enable the function.
- Symptom: The content extraction module cannot properly parse printing process sheets in a self-hosted environment, but runs normally on the official hosted deployment. Cause: The self-hosted environment does not have the corresponding format document parsing plug-in configured, or file storage permissions are insufficient to read the target documents.
How to confirm configurations are properly set
- Check the connectivity of each database connection configuration item. Run command line tests to verify the connection status of configurations such as
MONGODB_URIandREDIS_URL, ensuring no timeouts or authentication failures occur. - Upload a printing process sheet document. Verify that the document parsing module can normally extract field content, and confirm that the storage service configured via
STORAGE_S3_ENDPOINTcan normally read and write files. - After starting the Q&A service, the frontend address corresponding to
FE_DOMAINcan be accessed. Confirm that the interface loads normally and accepts inspection-related question submissions. - For FastGPT v4.17.0, adjust the
DB_MAX_LINKconfiguration, simulate high-frequency writing of order data, and observe that the service runs without connection pool overflow errors.
