Class QueryReplayHelper

java.lang.Object

io.temporal.internal.worker.QueryReplayHelper

public class QueryReplayHelper
extends java.lang.Object

Encapsulates a special query implementation for replaying workflow histories to support Worker.replayWorkflowExecution(io.temporal.internal.common.WorkflowExecutionHistory)

The implementation in this class doesn't execute under runId lock used in the main code path of Worker, so it shouldn't be using the workflow cache either.
