What this category’s data looks like
Auto parts investment research data primarily comes from automaker supporting announcements, industry association supply chain ledgers, official quotation sheets from parts suppliers, patent databases, and compliance standard documents. Update cadences vary by scenario:
- Vehicle model supporting BOM data iterates with new vehicle model launches
- Industry production capacity data is updated quarterly
- Patents and compliance standards are synchronized in real time
Most individual documents are structured tables or long text passages. Core fields include part number, material model, compatible vehicle model range, supplier entity, unit price, annual production capacity. Supported units include pieces, kilograms, yuan per piece, ten thousand pieces per year, and similar units.
What constraints these characteristics impose on database and operations workflows
Multi-source, heterogeneous data structures require the database to support both structured field queries and vector semantic retrieval, to meet investment research retrieval needs across different dimensions. Differentiated update cadences require a tiered storage strategy, to separate high-frequency real-time data from low-frequency historical ledgers and reduce operational costs. Core fields include multiple units and dimensions, so field validation rules must be configured to avoid retrieval errors caused by mismatched units or missing dimensions. Cross-vehicle compatible ranges require indexes that support multi-condition combined filtering, to improve precise retrieval efficiency.
Recommended Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Auto parts documents often include large BOM tables or multi-page compliance standards, which typically have large individual file sizes. This setting prevents import interruptions |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Structured table parsing requires traversing multiple rows and columns of data. Text splitting and vectorization preprocessing for complex documents take significant time, so a generous timeout window is needed |
VECTOR_SEGMENT_LENGTH | 800–1200 characters | Auto parts documents often include technical parameter passages. This length can fully retain the contextual information of a single parameter, avoiding semantic fragmentation |
RECALL_TOP_K | Top 10–15 results | Investment research retrieval requires balancing breadth and accuracy. This range can cover associated data across multiple suppliers and vehicle models, preventing key information from being missed |
MONGODB_REPLICA_SET_ENABLED | Enabled | Investment research data requires stable query performance and data consistency. Replica sets enable automatic failover, preventing service interruptions caused by single-node failures |
FIELD_VALIDATION_RULES | Configure unit and dimension validation per field | Core fields include multiple unit types. Validation must check for matching unit price and production capacity units, to avoid unit confusion during retrieval |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test against your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: Some part fields are empty after Excel import, or the import progress gets stuck above 90% without responding. Cause:
UPLOAD_FILE_MAX_SIZEis not configured to accommodate large BOM tables, or structured table parsing field mapping validation is not enabled. - Issue: MongoDB reports a replica set not initialized error during service startup, preventing successful deployment. Cause: The
MONGODB_REPLICA_SET_ENABLEDconfiguration item is not correctly enabled, or replica set node communication addresses are not configured. - Issue: Retrieval results include parts data with mismatched units, or conversation history lists fail to load and display properly. Cause:
FIELD_VALIDATION_RULESare not configured for unit validation, or persistent indexing configuration for conversation data is not enabled.
How to Verify Configurations Are Correct
- Upload a single auto parts document matching your business scenario, check the import progress and completeness of parsed results, and verify that all core fields are loaded correctly.
- Run a multi-condition combined retrieval, such as "compatible with specified vehicle model range + unit price parameters with corresponding units", and check if retrieval results match the filtering rules.
- Simulate a single-node failure, check if the database service automatically switches, and confirm that the replica set configuration is active.
- Trigger a conversation session operation, check if the conversation history list loads and displays normally, and confirm that persistent conversation data configuration is active.
