Request Id

reqId can be used for request link tracing, similar to the role of traceId in distributed systems. A request may need to pass through multiple services or modules to be completed. reqId is used to identify and associate all related operations of this request, so that we can trace and analyze the complete path of the request.
Using reqId has the following benefits:

• Request Tracing: By associating the same reqId with all related operations of a request, the complete path of the request in the system can be traced
• Performance Analysis: By analyzing a request's reqId, it is possible to understand the processing time of the request across various services and modules, thereby identifying performance bottlenecks
• Fault Diagnosis: When a request fails, the location of the problem can be identified by examining the reqId associated with the request

If the user does not set a reqId, the connector will internally generate one randomly, but it is still recommended that users set it to better associate it with user requests.
