v3.21.23

What’s Changed

• Implement sync workflow execution (fixes #659), upgrade to JDK 21, remove deprecated DynoQueue (#703) @v1r3n

  Synchronous Workflow Execution

  This PR introduces synchronous workflow execution capabilities, allowing clients to start a workflow and wait for it to complete (or reach a specific task) within a single HTTP request.

  New API Endpoint:

  • POST /api/workflow/execute/{name}/{version} - Execute a workflow synchronously with configurable wait conditions

  Key Features:

  • Wait for workflow completion or until a specific task reference is reached
  • Configurable wait timeout (default: 10 seconds)
  • Multiple return strategies: TARGET_WORKFLOW, BLOCKING_WORKFLOW, BLOCKING_TASK, BLOCKING_TASK_INPUT
  • Support for dynamic workflow definitions in request body
  • Idempotency via requestId parameter

  Supporting Changes:

  • New models: SignalResponse, WorkflowRun, TaskRun, WorkflowSignalReturnStrategy
  • Enhanced NotificationResult class with reactive support and blocking task detection
  • New ExecutorUtils for workflow traversal and blocking task identification
  • Enhanced WorkflowSweeper with improved notification handling
  • New SweeperProperties for sweeper configuration
  • Updates to Wait task to support signal-based workflow unblocking
  • Service layer additions in WorkflowService for sync execution support

  Infrastructure Improvements

  Dyno Queue Cleanup:

  • Removed deprecated DynoQueueDAO implementation
  • Cleaned up Dyno-specific Redis queue configurations
  • Removed RedisQueuesShardingStrategyProvider (no longer needed)
  • Added minimal Dyno connectionpool classes for backward compatibility

  JDK Upgrade

  • Upgraded to JDK 21

  Bug Fixes & Test Updates

  • Fixed workflow reconciliation and sweeper behavior
  • Updated test configurations across multiple modules
  • Fixed SQLite integration tests
  • Updated WorkflowResource tests for new sync execution endpoints
  • Removed obsolete test properties

  Fixes #659
