What the data for this category looks like
Policy and regulatory basis data for communication towers and infrastructure mainly comes from official public documents released by the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, and local communications administration departments, as well as operation and maintenance supporting specifications released by local communication infrastructure operators. The data update rhythm follows policy release cycles. Core policy documents see additions or revisions every quarter. The document structure is fixed, including policy document number, issuing authority, effective date, applicable scenario, and core clause content. Fields include policy level, coverage area, and clause number. Units use standard formats of item, date, and regional scope. The size of a single policy document is mostly between 10KB and 50KB.
What constraints these characteristics impose on the deployment and upgrade phase
The above data characteristics impose clear constraints on the deployment and upgrade phase. Policy documents from multiple departments have minor format differences. Configure format adaptation rules during deployment to avoid parsing failures. Update cycles are not fixed, and incremental data has no unified trigger node. Add scheduled task configuration for incremental pulling during the upgrade phase to ensure data synchronization timeliness. The fixed field structure requires that knowledge base mapping rules cannot be adjusted arbitrarily. Retain compatibility logic for original fields and indexes during upgrades. Multi-dimensional index requirements brought by regional coverage differences require configuring regional dimension retrieval filtering rules in advance during deployment to avoid cross-regional retrieval confusion.
How to set the configurations
| Configuration Item | Recommended Value | Rationale for this value |
|---|---|---|
MONGODB_URI | mongodb://admin:securepass@mongodb-host:27017/fastgpt_tower_policy?authSource=admin | Stores structured policy document data and retrieval indexes, matching the storage requirements of communication tower policy data |
REDIS_URL | redis://:redispass@redis-host:6379/0 | Caches frequently retrieved policy clauses to reduce concurrent access pressure on the database |
DB_MAX_LINK | 20–30 connections | Adapts to concurrent read/write requirements of multi-department policy data, avoiding database connection pool exhaustion |
STORAGE_S3_ENDPOINT | https://oss-cn-beijing.aliyuncs.com | Stores attachments of policy documents and parsed chunked data, compatible with public cloud storage standards |
FILE_TOKEN_KEY | A random secure string with a length of no less than 32 characters | Generates file access tokens to ensure access security of policy document attachments |
FE_DOMAIN | https://tower-policy.internal.com | Configures the frontend access domain name, adapting to the access path of internal operation and maintenance systems |
Three common mistakes
- Symptom: Error reported during Docker build when failing to load local policy document source. Cause: The local policy data directory was not mounted to the specified path of the build image, causing the build phase to fail to read the data source files.
- Symptom: API request returns 404 Not Found. Cause: The access permissions of the storage bucket corresponding to
STORAGE_S3_ENDPOINTwere not correctly configured, causing failure to read stored policy chunked data during retrieval. - Symptom: Policy retrieval results are empty after upgrading to FastGPT v4.17.0. Cause: The original database field mapping rules were not retained, causing the new code to fail to recognize the field format of the original policy data.
How to confirm the configuration is complete
- Execute the local build command
docker build -f ./projects/app/Dockerfile ., check that there are no dependency loading errors during the image build process, and confirm that the mount path matches the configuration items. - Initiate a policy retrieval test request, verify that the returned results include matching policy clauses, and confirm that the database and storage configurations are properly connected.
- View the scheduled task log, confirm that the incremental data pulling task executes every 6 hours as preset, with no abnormal interruption records.
- Log in to the FastGPT management backend, check that the knowledge base field mapping rules match the original policy data structure, and confirm that the upgraded compatibility logic is effective.
