What the data for this category looks like
Data for public transit declaration material and case review primarily comes from two sources: internal operation management systems of transit enterprises, and dedicated backend databases for route and station declarations. There are two data update cadences: one-time temporary declarations that update in real time upon submission, and monthly bulk route adjustment declarations that sync each natural month. Each case document includes declaration subject information, basic route or station parameters, supporting material attachment indexes, and review circulation records. Core fields include route number, approved passenger capacity, departure interval, declaration reason, and submission time. Their corresponding units are string, person, minutes per trip, text, and YYYY-MM-DD formatted date respectively.
What constraints these characteristics impose on workflow orchestration
Since data sources include multiple internal systems, workflows must be configured with cross-source data fetch nodes to handle field format differences across systems. Declaration cases include multiple supporting materials, so workflows must add an attachment verification step to ensure material completeness meets review requirements. Temporary declarations submitted in real time must trigger an immediate workflow, while bulk monthly declarations require scheduled execution nodes. Some fields have inconsistent units, such as variations in how departure interval is described. Workflows must include built-in unit conversion logic to unify standards. Review circulation records must be synced to workflow nodes to ensure state traceability.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Trigger Mode | Trigger on new data submission; set bulk tasks to execute daily at 2:00 | Matches the real-time and bulk update cadence of transit declaration data |
variables | Bind the three core fields: route number, approved passenger capacity, departure interval | Reuse core business data across nodes to reduce duplicate configuration |
nodeId | Assign a unique identifier to each verification node | Facilitate workflow debugging and state tracking, quickly locate abnormal nodes |
| Attachment Verification Node | Check that the number of material attachments is no less than 3 | Matches the legal supporting material requirements for transit declarations |
| Context Length | 800–1200 characters | Adapts to the average text length of single-case declaration materials |
| Retry Configuration | 3 retries, timeout threshold 600 seconds | Addresses network fluctuations when fetching data across systems |
Three Common Mistakes
- Workflow calls to
variablesreturn empty fields. The cause is that the binding mapping for transit declaration core fields was not completed in the global variable configuration. - Workflow runs throw timeout errors with status code 504. The cause is that no reasonable timeout threshold was set, and cross-system data fetching time exceeds the system's default limit.
- Workflows cannot associate multiple knowledge bases. The cause is that the call permissions and node trigger logic for multiple knowledge bases were not configured correctly.
How to Confirm Proper Configuration
- Submit a test declaration case, verify whether the workflow starts automatically according to the configured trigger mode.
- Enter the workflow debugging interface, check whether the core fields bound in
variablesare displayed correctly. - Simulate cross-system data fetch operations, verify whether node execution status meets expectations.
- Check the multiple knowledge base association configuration, confirm that the review node can normally call compliant content from the corresponding knowledge base.
