Temporal has introduced improvements to its developer experience for Signal and Update handlers to address challenges like concurrency issues, initialization problems, and incomplete handlers in Workflows. These enhancements include the introduction of synchronization primitives across all Temporal SDKs to handle interleaved signals without using queues, Workflow Initialization Methods for ensuring state readiness before message handling, and a method to confirm that all handlers have finished before a Workflow exits to prevent data inconsistency. While these updates promote the use of handler styles for interactive Workflows, queues remain a robust option for scenarios requiring precise control over message processing order and timing. The changes aim to simplify the creation of powerful, interactive Workflows with fewer bugs, and extensive documentation and samples have been provided to guide developers in adopting these new practices.
