What the data for this category looks like
Data sources for shipping port yield rates include public statistical APIs from the international shipping industry, structured daily reports submitted by port operators, and route operation data from maritime regulatory authorities. This data primarily serves yield rate and market briefing needs for shipping finance. Data update rhythm falls into two categories: core daily data updates at a fixed time each day, and real-time route freight rate data refreshes every hour. Most data is in structured table format, including fields such as port name, berth number, daily throughput, per-container operating cost, route yield range, and corresponding shipping company code. Units include TEU, yuan, US dollars, and voyage duration, among others.
What constraints these characteristics impose on the "form and interaction" link
Structured data formats require forms to support bulk import and structured parsing, to avoid adaptation costs from scattered text input. Data sources with multiple update frequencies require forms to configure two trigger modes, to meet needs for daily scheduled pulling and real-time manual refresh. Fields with mixed units require interaction components to support automatic unit matching and conversion, to prevent data anomalies caused by incorrect user input units. Interval data fields require forms to add interval input validation, and clearly prompt valid value ranges in interaction feedback. Standardized code fields require dropdown selection components, to reduce error probability from manual input.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Shipping port data documents usually contain multi-field structured content, which takes longer to parse. 600 seconds covers the complete parsing process |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single structured data file for daily port operation reports is usually large in size. 1000 MB meets bulk import needs |
Recall count | Top 8 entries | Core fields of shipping port yield rate data are concentrated in the top ten entries. Excessive recall increases redundant computation |
Similarity threshold | 0.75–0.85 | Matching accuracy requirements for fields such as port codes and route names are high. This interval filters irrelevant data with low matching degrees |
formFieldAutoMatch | Enabled | The field names of structured data have high matching degrees with system preset fields. Automatic matching reduces manual configuration workload |
Scheduled Trigger Task Interval | 1440 minutes | Shipping port yield rate daily reports are updated daily. One scheduled pull per day meets requirements |
The parameter values provided on this page are all common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing the configuration.
Three Common Mistakes
- Phenomenon: A 413 Request Entity Too Large error is displayed on the interface after uploading a port operation data file on the domestic SaaS version V4.8.17, while the text conversation function works normally. Cause: The
UPLOAD_FILE_MAX_SIZEparameter was not adjusted, and the default value is too small, causing large file upload failure. - Phenomenon: The yield rate briefing result fields generated by the form are missing, and only partial port data is displayed. Cause:
formFieldAutoMatchwas not enabled, and the structured data fields were not automatically matched to the system's preset fields, resulting in incomplete parsing. - Phenomenon: The scheduled yield rate daily report briefing is delayed by more than 2 hours. Cause:
PARSE_FILE_TIMEOUT_SECONDSwas set too short, and did not cover the parsing process of large data files, resulting in task interruption.
How to Confirm the Configuration is Complete
- Upload a test structured port data file, check that the upload progress bar completes normally with no error prompts.
- Manually trigger a data parse on the form configuration page, check that the parsed fields exactly match the header of the uploaded file.
- Configure a scheduled trigger task, check that the task log executes normally at the set time with no timeout errors.
- Call the form interaction interface, enter a specified port code, check that the returned yield rate data includes correct units and field values.
