Parallelization sends one input through two or more processing paths concurrently, then aggregates their results. In an agent workflow, it answers several related questions at once before a final summarizer produces one response. section 12.2.3 section 12.1
A Spring implementation uses:
- A ParallelizerAction that receives injected worker actions. section 12.2.3
- CompletableFuture and a fixed thread pool to execute workers independently without blocking each other. section 12.2.3
- Aggregation into one dashed-separated String, followed by a SummarizerAction. section 12.2.3
- A Chain configuration that runs rule retrieval, parallel analysis, and summarization in sequence. section 12.2.3
Board-game question answering
For a question about Azul, one worker determines the player count while another determines game mechanics. Their results are combined and summarized into a single answer. section 12.2.3
Figure 12.3 Performing actions in parallel
Use the workflow figure to see how one input branches into parallel actions before converging on summarization. section 12.2.3
