What the data for this category looks like
Data sources include policy documents on steel industry capacity replacement, pollutant discharge, work safety, smelting process specifications, etc., released by the State-owned Assets Supervision and Administration Commission of the State Council, Ministry of Industry and Information Technology, Ministry of Ecology and Environment, and local industrial and information departments. National standard policies are revised every 3 to 5 years. Local implementation rules are updated quarterly. Document structure includes fields such as policy document number, issuing authority, effective date, applicable smelting processes (blast furnace, converter, electric arc furnace, etc.), clause content, and penalty standards. Units include mg/m³, ten thousand tons/year, hour, etc. Single document length varies widely, from hundreds of characters to over ten thousand characters.
What constraints do these characteristics impose during deployment and upgrade
The long-text nature of iron and steel smelting policies leads to uneven token consumption for embedding models. Adjust concurrent parameters for large file processing during deployment. Policy update frequencies vary widely, with frequent incremental synchronization requirements. Comply with scheduled incremental update logic during upgrades. Policy metadata is classified by smelting process. Configure corresponding indexes in the database to improve retrieval efficiency. Storage of multi-source policy data requires adaptation to large file requirements, which imposes capacity and bandwidth requirements on storage nodes. Reference only; verify against the target FastGPT release and deployment documentation.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 concurrent connections | There are many metadata fields for iron and steel smelting policy data. Excessively high concurrent connections will cause database load overload, while excessively low values will affect retrieval response speed. Calibrated based on actual measurements. |
MONGODB_URI | Add process type and effective date indexes | Iron and steel policies require filtered retrieval by smelting process and release time. Indexes can greatly improve the efficiency of filtered queries. |
REDIS_URL | Configure cache rules with a 600-second expiration period | Caching frequently retrieved policy clauses for 600 seconds reduces repeated database query pressure, and adapts to policy update frequencies. |
STORAGE_S3_ENDPOINT | Bind nodes that support large file storage | Some full-text iron and steel policy documents exceed 10,000 characters, requiring adaptation to large file storage and parsing requirements. |
FE_DOMAIN | Fill in the public network domain name of the deployment node | Ensure normal cross-domain access between front-end and back-end services, and adapt to multi-terminal access scenarios. |
ROOT_KEY | Use a high-strength random string | Ensure access security for background management interfaces, and avoid unauthorized configuration modification operations. |
Three common errors during configuration
- Phenomenon: Retrieved policy chunks exceed the set reference limit, and the returned content token count exceeds the preset threshold. Cause: No token-based chunk truncation rule is configured. Only the number of retrieved matching entries is limited, and the length of single matching results is not verified.
- Phenomenon: Model concurrent access times out, returning a 504 status code. Cause:
DB_MAX_LINKis set too high, causing the database connection pool to be exhausted and unable to respond to retrieval requests in a timely manner. - Phenomenon: Tool calls fail only after upgrading FastGPT. Cause: The tool call cache configuration corresponding to
REDIS_URLis not updated synchronously, causing the old interface address to not be correctly mapped.
How to confirm the configuration is correct
- Log in to the FastGPT background management interface, check the configuration value of
DB_MAX_LINK, and verify that the concurrent connection number is within the set 20–30 range. - Upload a ten-thousand-plus-character iron and steel smelting policy document, and verify that the storage node can normally receive and complete parsing and storage.
- Initiate a retrieval request filtered by converter smelting process, and verify that the returned results only include policy content corresponding to this process.
- Check the Redis cache log, and verify that frequently retrieved policy clauses are correctly cached within 600 seconds.
