What the data for this category looks like
The main entities in this category are electroplating plants, electronic connector and hardware surface treatment workshops. Daily documents include bath solution analysis records, process parameter cards, fixture records, film thickness and adhesion reports, hazardous waste ledgers, and wastewater monitoring records. Data sources cover customer surface treatment specifications, bath solution test results, rectifier operation data, online water quality monitoring data, and hazardous waste management ledgers. Update frequencies include per bath cycle, per shift, and scheduled updates per monitoring requirements. Documents include numeric parameters such as bath solution temperature and current density, text records such as rack plating position descriptions, and compliance ledger-style documents.
What constraints these characteristics impose on the deployment and upgrade phase
Data sources for this category are scattered and updated frequently. High-frequency updates per bath cycle and per shift generate a large volume of document write and index requests. This places clear requirements on the read and write performance of storage and index services. Mixed storage of multiple document types requires configuring index rules that adapt to both structured parameters and unstructured ledgers, to ensure matching accuracy for cross-review. Documents involve hazardous waste and wastewater monitoring content, which imposes strict requirements on data storage security and compliance. During the upgrade process, index synchronization frequency must match production update rhythms, to avoid data lag that affects the effectiveness of cross-review. Additionally, cross-departmental document collaboration requires deployed services to have stable cross-domain access configurations, to ensure access permissions and data synchronization for personnel in different roles.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
REDIS_URL | redis://<internal IP>:6379/0 | Hosts index task queues and status caches. Internal network addresses reduce network latency. Database 0 isolates business data |
MONGODB_URI | mongodb://<username>:<password>@<cluster address>:27017/fastgpt?authSource=admin | Stores document metadata and index vectors. Cluster mode adapts to high-frequency write requests |
STORAGE_S3_ENDPOINT | https://<cloud storage regional endpoint> | Stores uploaded technical documents and monitoring reports. Regional endpoints enable nearby access to improve upload speeds |
DB_MAX_LINK | 200–300 | Adapts to high-frequency document write and retrieval requests across multiple bath cycles, preventing database connection exhaustion |
FE_DOMAIN | Fill in the actual deployed frontend access domain name | Configures cross-domain access permissions to ensure normal communication between the frontend interface and backend APIs |
Three common mistakes
- Symptom: File status remains "Indexing" with no progress updates. Cause:
REDIS_URLis not configured correctly, or the used embedding model is incompatible with FastGPT v4.17.0, preventing index tasks from proceeding normally. - Symptom: Redis image pull fails in docker-compose.yml, and services cannot start. Cause: The correct mirror address is not specified, or server network permissions restrict access to public mirror repositories.
- Symptom: Retrieval results deviate significantly from actual process parameters, and cannot match the latest bath solution adjustment records. Cause: The index synchronization cycle is not configured according to document update frequencies, leading to index data lagging behind actual production data.
How to confirm the configuration is complete
- Run the docker-compose up command, check the startup logs of redis, mongodb and other services. No errors indicate completion of basic service configuration verification.
- Upload a bath solution analysis record document, wait 10–15 minutes, and confirm the document status changes to "Indexed". This verifies that the index process is working normally.
- Access the configured
FE_DOMAINaddress, log in, and attempt to retrieve process parameter card content. Valid returned results indicate that the retrieval link is working normally. - Check the database connection monitoring dashboard, confirm that the actual connection count does not exceed the
DB_MAX_LINKconfiguration threshold. This verifies that the database connection configuration is valid.
