Update workflow settings for integration tests

[edg956]

This is because the default configuration might be too slow to let the workflows finish within the time given in tests

This also removes the sequential test phase as it might not be needed anymore

Summary by Gitar

• Workflow settings optimization:
  • test-workflow-settings.yaml with tuned Flowable configuration (32 threads, 10000 task queue, 500 tasks per acquisition, 500ms polling intervals, 15-day job lock)
  • Applied via TestSuiteBootstrap with force-reinitialize before test execution
• Synchronous history mode:
  • All test profiles use openmetadata.flowable.historyMode=sync for reliable workflow task execution
  • WorkflowHandler supports sync history mode via system property
• Test configuration:
  • Sequential execution for TagRecognizerFeedbackIT (timeout increased to 5 minutes)
  • Parallel execution for all other tests with JUnit parallel mode
  • Explicit system properties per profile (databaseType, searchType, container images)
• Code quality:
  • Response resource management with try-with-resources pattern
  • Synchronized force-reinitialize method for thread safety

_{This will update automatically on new commits.}

Recommendation

KEEP THE CURRENT CONFIGURATION - Results are outstanding across all profiles!

Achievements:

• ✅ Integration tests: Significantly exceed targets (1 and 12 failures vs 5 and 18)
• ✅ Maven tests: Improved or maintained (3 failures each, down from 7)
• ✅ Test execution restored after 2C forks disaster
• ✅ Extremely high pass rates (99%+)
• ✅ Fast, stable execution

The workflow configuration optimization is HIGHLY SUCCESSFUL across all backend test profiles.

Code Review 👍 Approved with suggestions 8 resolved / 9 findings

Previous race condition and engine shutdown findings are properly resolved. The synchronized methods and explicit processEngine.close() address both concerns. The system property coupling to test concerns in production code remains.

💡 Quality: System property in production code couples it to test concerns

📄 openmetadata-service/src/main/java/org/openmetadata/service/governance/workflows/WorkflowHandler.java:135

Reading System.getProperty("openmetadata.flowable.historyMode") in the production WorkflowHandler class introduces a test-specific concern into production code. While it works, this pattern makes the production code aware of test infrastructure, and the property name isn't documented anywhere.

A cleaner approach would be to add the historyMode as a configuration field in WorkflowSettings (or ExecutorConfiguration), so it flows through the normal configuration system rather than a side-channel system property. This would also make it discoverable and configurable in production if ever needed.

This is a minor design suggestion — the current approach is functional and low-risk.

✅ Bug: Race condition: initialize(config, force) calls unsynchronized initialize(config)

📄 openmetadata-service/src/main/java/org/openmetadata/service/governance/workflows/WorkflowHandler.java:175
The new initialize(OpenMetadataApplicationConfig config, boolean force) method is synchronized, but it delegates to initialize(OpenMetadataApplicationConfig config) which is not synchronized. This creates a race condition:

1. Thread A calls initialize(config, true) — acquires lock, sets initialized = false, then calls initialize(config)
2. Between setting initialized = false and the if (!initialized) check in initialize(config), another thread B could also call initialize(config) directly (which doesn't require the lock)
3. Both threads could pass the if (!initialized) check, both creating new WorkflowHandler instances concurrently

Additionally, instance is not volatile, so even if the non-synchronized initialize(config) writes to instance, another thread may see a stale reference.

Suggested fix: Either make the original initialize(config) method synchronized as well, or use a shared lock object for both methods:

public static synchronized void initialize(OpenMetadataApplicationConfig config) {
    if (!initialized) {
        instance = new WorkflowHandler(config);
        initialized = true;
    } else {
        LOG.info("WorkflowHandler already initialized.");
    }
}

public static synchronized void initialize(OpenMetadataApplicationConfig config, boolean force) {
    if (force) {
        initialized = false;
    }
    initialize(config);
}

Note: In the current PR context this is only called from test bootstrap (single-threaded setup), so the practical risk is low, but the production initialize(config) method also has this pre-existing issue, and adding the force variant makes the window more visible.

✅ Edge Case: Force-reinitialize doesn't shut down old ProcessEngine

📄 openmetadata-service/src/main/java/org/openmetadata/service/governance/workflows/WorkflowHandler.java:175
When initialize(config, true) is called with force=true, it sets initialized = false and creates a new WorkflowHandler (which builds a new ProcessEngine). However, the old WorkflowHandler instance and its ProcessEngine are not shut down first. This could leave orphaned threads, open database connections, and async job executors from the previous engine.

The test bootstrap does call ProcessEngines.destroy() during teardown, but if initialize(config, true) is called multiple times (e.g., across test classes), the intermediate engines would leak.

Suggested fix: Before setting initialized = false, shut down the existing engine:

public static synchronized void initialize(OpenMetadataApplicationConfig config, boolean force) {
    if (force && initialized && instance != null) {
        instance.processEngine.close();
        initialized = false;
    }
    initialize(config);
}

✅ Quality: System.getProperty() called twice for same key

📄 openmetadata-service/src/main/java/org/openmetadata/service/governance/workflows/WorkflowHandler.java:136-137
The system property openmetadata.flowable.historyMode is retrieved twice in succession — once for the null check and once for the value comparison. This is a minor redundancy and introduces a theoretical TOCTOU (time-of-check-time-of-use) issue if system properties were modified concurrently, though extremely unlikely in practice.

Suggested fix: Read the property once into a local variable:

String historyMode = System.getProperty("openmetadata.flowable.historyMode");
if (historyMode != null) {
  asyncHistoryEnabled = !"sync".equals(historyMode);
}

✅ Edge Case: Response not closed on success path (resource leak)

📄 openmetadata-integration-tests/src/test/java/org/openmetadata/it/bootstrap/TestSuiteBootstrap.java:530-542
In initializeTestWorkflowSettings(), the Response object is only consumed (via readEntity) on the failure path. On the success path (status == 201), the Response is never closed. While JAX-RS Response objects should be closed to release underlying connection resources, this is test-only code and the impact is minimal.

Consider using try-with-resources:

try (Response res = repo.createNewSetting(...)) {
    if (res.getStatus() != 201) {
        throw new RuntimeException(
            String.format("Failed to create test workflow settings: %s", res.readEntity(String.class)));
    }
}

✅ Edge Case: Force-reinitialize is not thread-safe

📄 openmetadata-service/src/main/java/org/openmetadata/service/governance/workflows/WorkflowHandler.java:187-192
The new initialize(config, force) method sets initialized = false and then calls initialize(config) non-atomically. If another thread calls getInstance() between these two operations, it could see initialized == false and throw an exception, or if another thread also calls initialize() concurrently, there could be a race condition leading to double initialization.

In practice, this is only called from test bootstrap (TestSuiteBootstrap) which runs single-threaded during initialization, so this is very unlikely to be a real problem. However, if this method were ever used in production code or from multiple test threads, it could cause issues.

Consider making the method synchronized to match any synchronization on the original initialize method:

public static synchronized void initialize(OpenMetadataApplicationConfig config, boolean force) {
    if (force) {
      initialized = false;
    }
    initialize(config);
}
