What the data for this category looks like
Coal mining production policy and regulatory basis data primarily comes from official public documents issued by the National Energy Administration, National Mine Safety Administration, provincial coal industry management departments, and industry standards released by coal industry associations. The update cycle is not fixed. Updates are synchronized when new safety production regulations or production standards are issued. Internal production rules are revised quarterly or annually. Individual document lengths range from several pages to dozens of pages, and include fields such as document number, issuing authority, effective date, applicable mine type, clause number, penalty details, and more. Clauses are organized by "article", "paragraph", and "subparagraph". Dates use the YYYY-MM-DD format.
What constraints these characteristics impose on the deployment and upgrade phase
The large volume and multi-field nature of coal mining policy documents requires sufficient database connection pool and vector storage resources during deployment, to avoid performance bottlenecks during retrieval. Policy updates have no fixed cycle, so the upgrade process must support incremental synchronization to prevent overwriting previously annotated policy data. The professional terminology and precise field requirements in documents require configuring metadata filtering rules during deployment, to ensure retrieval results only return policy clauses directly related to coal mining production. Additionally, storage and access to public policy documents must comply with industry standards, so access control policies must be updated during upgrades.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://fastgpt:yourpass@mongodb:27017/fastgpt?maxPoolSize=18 | The large volume of coal mining policy documents requires an appropriate connection pool to balance concurrent retrieval and resource usage |
REDIS_URL | redis://:redispass@redis:6379/1?maxmemory=10000 MB | Cache policy document metadata and retrieval results to reduce repeated database query pressure |
DB_MAX_LINK | 15–25 | Adapt to the concurrent request volume of coal mining policy retrieval, to avoid exhausting database connections |
STORAGE_S3_ENDPOINT | https://s3-cn-north-1.amazonaws.com | Store attachments such as PDF versions and scanned copies of original policy documents, to unify management of unstructured data |
FILE_TOKEN_KEY | Custom 32-character random string | Encrypt access tokens for knowledge base attachments, to prevent unauthorized downloading of policy documents |
ROOT_KEY | Custom high-strength secret key | Initialize the highest permission key for FastGPT deployment, used to configure knowledge bases and applications |
Three common mistakes
- Symptom: All previously created policy Q&A applications disappear after upgrading to FastGPT v4.17.0. Cause: Local data volume persistent storage for application configurations and knowledge base metadata was not mounted during upgrade, so temporary storage content was cleared after container restart.
- Symptom: 504 timeout errors occur when retrieving coal mining policy documents. Cause: The value of
DB_MAX_LINKwas not adjusted, and the database connection pool capacity was insufficient, causing a backlog of retrieval requests leading to timeouts. - Symptom: Official PDF attachments of policy documents cannot be previewed normally. Cause:
STORAGE_S3_ENDPOINTand the access permissions of the corresponding storage bucket were not configured correctly, making it impossible to pull attachment resources.
How to confirm the configuration is complete
- Access the FastGPT management backend, enter the policy knowledge base page, and verify that the number of documents matches the local source file directory.
- Initiate a test query targeting coal mine safety production policies, confirm that the returned results include correct clause numbers and issuing authority information.
- Review Redis monitoring metrics, confirm that the cache hit rate is within a reasonable range, calibrated based on actual concurrent retrieval volume.
- Upload a coal mining policy PDF attachment, confirm that it can be previewed normally in the knowledge base and retrieved.
