What the data for this category looks like
The policy and regulatory basis data for new energy development comes primarily from officially published documents of national development and reform commissions, national energy administrations, and energy authorities of various provinces and cities. New policy releases trigger data updates, with no fixed cycle. Individual documents include fields such as policy title, document number, issuing authority, release date, main text clauses, and supporting attachments. Some files include supplementary information like applicable regions, industry categories, and validity periods. Document lengths vary widely, from thousand-word management regulations to hundred-word notices.
What constraints these characteristics impose on deployment and upgrade
Wide variation in policy document lengths means chunking and vector encoding long documents uses more server resources. Deployments require matching reasonable storage and computing configurations. Differences in policy formats across multiple sources require configuring unified preprocessing rules during deployment to adapt to documents with varying numbers and structures. The lack of a fixed update cycle requires supporting incremental synchronization upgrade logic to prevent service interruptions from full reconstruction. Some policies include supplementary fields for regions and industry categories. Deployments must reserve index space for these fields to ensure accurate retrieval and filtering.
How to Set Configuration Values
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://user:pass@host:27017/fastgpt?maxPoolSize=50&retryWrites=true | Adapts to the batch read and write requirements of new energy policy data. Setting maxPoolSize to 50 balances concurrency and server load, avoiding connection pool exhaustion |
DB_MAX_LINK | 800–1200 characters | Covers the main text length of most new energy policy documents, prevents vector encoding failures caused by overly long individual chunks, and controls storage and transmission overhead for single-chunk data |
STORAGE_S3_ENDPOINT | Configure according to the actual address of the local object storage service | New energy policies come with a large number of supporting attachments. Object storage must be used for unified management to ensure the stability of attachment retrieval and export |
REDIS_URL | redis://:password@host:6379/1 | Caches frequently queried policy entries to reduce database read and write pressure, adapting to daily query scenarios for new energy policy Q&A |
ROOT_KEY | Custom key string with a complexity of no less than 16 characters | Ensures the security of system background operations, preventing unauthorized modification of knowledge base configurations and data export |
FILE_TOKEN_KEY | Custom 32-character random string | Used to encrypt access links for knowledge base attachments, ensuring the security of attachment downloads |
Three Common Configuration Mistakes
- Server memory continues to rise, and OOM errors are triggered at fixed times each day. Cause: The
DB_MAX_LINKparameter is not adjusted according to the length characteristics of new energy policy documents, leading to too many documents imported in a single batch and exhausting the database connection pool.
Reference only; verify against the target FastGPT release and deployment documentation.
- When importing a knowledge base across instances, only a single CSV file is generated, and the original multi-file classification structure cannot be retained. Cause: The association parameters between
FILE_TOKEN_KEYand object storage are not correctly configured, causing attachment files to not be exported synchronously with the knowledge base.
How to Verify Correct Configuration
- Batch import 10 new energy policy documents of different lengths, check that server memory usage remains stable, and no OOM errors are triggered.
- Connect to the configured
MONGODB_URI, verify that the number of database connection pool connections does not exceed the set maxPoolSize value. - Export the current knowledge base, check that attachment files are generated synchronously with knowledge base entries, with no missing or abnormal formats.
- Attempt to access the background management interface after modifying
ROOT_KEY, verify that unauthorized access is successfully blocked.
