Batch Trace Manager Decorators for Distributed Tracing Link Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traditional distributed tracing systems, batch processing of requests often breaks trace links, resulting in disconnected traces when requests pass through child services, making it difficult for developers to track end-to-end message processing and identify errors or performance issues.
Innovation Solution
A batch trace manager is introduced to generate decorators that link incoming traces with new traces created by child services, maintaining trace links through a distributed tracing service, allowing for bi-directional linking and providing a complete view of message processing by combining linked traces.

Engineering Contradiction Analysis
1Productivity
If batch processing of requests is implemented in child services, then processing efficiency is improved, but trace links are broken resulting in disconnected traces
Solution Approach 1:
A batch trace manager is introduced as an intermediary component that receives incoming traces, generates decorators containing trace linking information, and sends them to the distributed tracing service. This mediator enables batch processing while preserving trace continuity by bridging the gap between batch processing operations and trace tracking requirements.
Solution Approach 2:
The system performs preliminary actions by generating trace decorators before the actual batch processing occurs. The batch trace manager creates linking information in advance that associates incoming traces with the batch processing operation, ensuring that trace continuity is established before the batch processing breaks the links.
2Reliability
If trace decorators are generated and sent to distributed tracing service, then trace linking is maintained, but system complexity increases
Solution Approach 1:
The tracing system is segmented into distinct functional components: the batch trace manager that handles trace decorator generation, the distributed tracing service that stores and manages trace links, and the child services that perform batch processing. This segmentation allows each component to have a specific responsibility, making the overall complex system more manageable and maintainable.

AI summary
Techniques for distributed tracing for batch workloads using trace linking are described. A method of distributed tracing for batch workloads using trace linking includes generating a decorator by a batch trace manager, the decorator identifying at least one first trace to be linked to at least one second trace, the at least one second trace corresponding to a message processed by a child service in a provider network, sending the decorator to a distributed tracing service in the provider network, and adding a virtual trace to a virtual trace map by the distributed tracing service, the virtual trace linking the at least one first trace and the at least one second trace.
