What the data for this category looks like
Logistics investment research data sources include freight bills, port dispatch logs, trunk line transportation tracks, warehouse inbound and outbound records, industry freight rate indices, and special policy documents. Update rhythms vary significantly: real-time transportation tracks are updated per second, freight rate indices are released daily, and policy documents and batch freight reports are archived irregularly. Single structured waybill data includes unit-bearing fields such as waybill number, origin and destination, cargo type, weight, transportation method, and lead time. Unstructured documents are dispatch analysis reports ranging from thousands to tens of thousands of characters, with formats including tables, plain text, and chart descriptions.
What constraints these characteristics impose on deployment and upgrade
The multi-source heterogeneity and inconsistent update rhythms of logistics investment research data require adapting streaming parsing queues and multi-format parsing plugins during deployment to prevent loss of real-time track data. Special unit-bearing fields such as weight and transportation lead time need unified mapping rules. Do not arbitrarily modify pre-configured field mappings during upgrades, as this will cause index confusion. Parsing long-text analysis reports takes a long time. During upgrades, retain old parsing rules to maintain compatibility with existing data, and do not interrupt incremental synchronization tasks to ensure continuous access to real-time data.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Meets parsing time requirements for long logistics dispatch reports and batch track logs |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Supports batch uploads of multiple files such as freight bills and monthly warehouse reports |
maxContext | 8000–12000 characters | Covers the context recall length required for long-document investment research analysis |
Recall count | Top 8 results | Matches the retrieval needs of logistics investment research, which requires covering multi-dimensional track, freight rate, and policy data |
Similarity threshold | 0.75–0.85 | Filters irrelevant freight data and retains retrieval results highly relevant to investment research topics |
PARSE_CHUNK_SIZE | 1000–1500 characters | Adapts to the paragraph structure of logistics documents and avoids segmenting that breaks business logic |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: When upgrading a private deployment, the version upgrade entry cannot be found in the interface, or the upgrade documentation for the corresponding version cannot be located. Cause: Did not switch to the private deployment-specific documentation category, and mistakenly used cloud deployment upgrade guide content.
- Issue: After calling the
/api/v1/parse/fileinterface to upload a freight file, the returnedtaskIdfield is empty, and the completion status of parsing and indexing cannot be confirmed. Cause: ThePARSE_NOTIFY_URLparameter is not configured, or the asynchronous parsing callback switch is not enabled, causing the task status to not be synchronized to the calling end. - Issue: After an upgrade, field recognition errors occur in batch-uploaded waybill data, such as weight fields being mistakenly identified as volume fields. Cause: The pre-configured custom field mapping rules were overwritten during the upgrade, and the configuration file was not backed up in advance.
How to confirm the configuration is correct
- Upload a typical logistics freight analysis report, check the text segmentation effect after parsing, and adjust the segmentation length configuration based on the document's paragraph structure.
- Call the file upload interface to generate a parsing task, verify that the task ID is returned normally, and confirm that the callback configuration trigger logic meets expectations.
- Compare the custom field mapping rules before and after the upgrade to ensure that the mapping relationships for logistics-specific fields have not been accidentally modified.
- Start a batch freight data synchronization task, monitor the running status of the parsing queue, and adjust the timeout configuration based on the data update frequency.
