TECH_DEBT: Measure debuggability #572
Conversation
…ice as a whole which compiles the measures in the cache with "debug" logging enabled * Modified the $evaluate operation to accept a "debug" parameter and always compile the measure for every request so that the debug logging flag is always respected * Updating logback config so that it is configured to always use DEBUG logging for the DebugUtilities class. This class only outputs debug logs when the compiled measure is configured for debug logging. * Added stub for getting a specific line of CQL from the measure, so that the debug logging output from cqframework can be more easily traced to specific lines of CQL that are loaded in the measure eval system. * FileSystemInvocation always has cql debug logging enabled * Measures compiled into cache use whatever cql-debugging the service is configured for * Measure evaluation using the REST $evaluate operation always compiles the measure and uses whatever is passed in (or default of "false") in the operation request * Created a custom extension of InMemoryFhirRepository called LinkInMemoryFhirRepository that overrides the `transaction()` operation with a basic implementation of the operation so that logs aren't littered with NotImplementedExceptions()

🧹 Nitpick comments (16)
Java/measureeval/src/main/resources/application.yml (1)
54-54: Consider adding documentation for the new configuration property.To improve maintainability, consider adding a YAML comment above the property to explain:
- Its purpose in controlling CQL debugging
- Impact on logging and performance
- When it should be enabled/disabled
reportability-predicate: com.lantanagroup.link.measureeval.reportability.IsInInitialPopulation + # Controls detailed CQL debugging output during measure evaluation + # Enable only for development/troubleshooting as it may impact performance cql-debug: falseJava/measureeval/src/main/java/com/lantanagroup/link/measureeval/FileSystemInvocation.java (2)
Line range hint
141-147: Update method documentation to reflect new debugging capability.The method signature changes look good - removing the redundant
patientBundlePathparameter and adding theisDebugparameter for CQL debugging makes sense. However, the method's documentation should be updated to explain the new debugging capability.Add Javadoc to explain the purpose of the
isDebugparameter:+/** + * Evaluates a patient bundle using the provided measure evaluator. + * @param patientBundle The bundle containing patient data to evaluate + * @param start The start date for the measurement period + * @param end The end date for the measurement period + * @param evaluator The compiled measure evaluator + * @param isDebug Whether to enable detailed CQL debugging output + */ private static void evaluatePatientBundle(Bundle patientBundle, String start, String end, MeasureEvaluator evaluator, boolean isDebug) {
174-174: Consider making debug mode configurable via command line.Currently, debug mode is hard-coded to
truein both invocations. While this makes sense for a debugging utility, it would be more flexible to make it configurable via command line arguments.Consider updating the main method to accept an optional debug flag:
public static void main(String[] args) { - if (args.length != 4) { - System.err.println("Invalid number of arguments. Expected 4 arguments: <measure-bundle-path> <patient-bundle-path> <start> <end>"); + if (args.length < 4 || args.length > 5) { + System.err.println("Usage: <measure-bundle-path> <patient-bundle-path> <start> <end> [debug]"); System.exit(1); } String measureBundlePath = args[0]; String patientBundlePath = args[1]; String start = args[2]; String end = args[3]; + boolean debug = args.length == 5 ? Boolean.parseBoolean(args[4]) : false; try { Bundle measureBundle = getBundle(measureBundlePath); - MeasureEvaluator evaluator = MeasureEvaluator.compile(fhirContext, measureBundle, true); + MeasureEvaluator evaluator = MeasureEvaluator.compile(fhirContext, measureBundle, debug);Then update the invocations to use this flag:
- evaluatePatientBundle(patientBundle, start, end, evaluator, true); + evaluatePatientBundle(patientBundle, start, end, evaluator, debug);Also applies to: 178-178
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/repositories/LinkInMemoryFhirRepository.java (2)
11-17: Consider adding parameter validation in constructors.While the constructors correctly delegate to the parent class, it would be safer to add null checks for the parameters.
Consider adding validation:
public LinkInMemoryFhirRepository(FhirContext context) { + if (context == null) { + throw new IllegalArgumentException("FhirContext cannot be null"); + } super(context); } public LinkInMemoryFhirRepository(FhirContext context, IBaseBundle bundle) { + if (context == null) { + throw new IllegalArgumentException("FhirContext cannot be null"); + } super(context, bundle); }
19-35: Consider performance optimizations and monitoring capabilities.Given this is part of a measure evaluation system, consider these architectural improvements:
- Add batch processing for large bundles to manage memory usage
- Implement monitoring/metrics for transaction processing
- Add debug logging for better visibility into resource processing
Example logging implementation:
@Override public <B extends IBaseBundle> B transaction(B transaction, Map<String, String> headers) { + log.debug("Processing bundle transaction with {} entries", + transaction instanceof Bundle ? ((Bundle) transaction).getEntry().size() : "unknown"); // ... existing code ... + log.debug("Completed bundle transaction processing"); return transaction; }Consider implementing batch processing if you need to handle large bundles:
private static final int BATCH_SIZE = 1000; private void processBatchedEntries(List<Bundle.BundleEntryComponent> entries) { for (int i = 0; i < entries.size(); i += BATCH_SIZE) { List<Bundle.BundleEntryComponent> batch = entries.subList(i, Math.min(entries.size(), i + BATCH_SIZE)); // Process batch } }Java/measureeval/src/main/resources/logback-cli.xml (1)
17-19: Consider the performance impact of increased root logging levelChanging the root logger from error to info level will significantly increase log volume, which could impact performance in production environments.
Consider:
- Using a more selective approach by setting specific loggers to info level instead of the root logger
- Making the root log level configurable through environment variables
- Maintaining separate logging configurations for production and development environments
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/utils/CqlLogAppender.java (2)
15-15: Expand Regex Pattern to Match All Valid Library IDsThe regex pattern
([\\w.]+)used inLOG_PATTERNmay not match library IDs containing hyphens or other special characters. If library IDs can include characters beyond word characters and dots, consider updating the regex to accommodate these characters.Apply this diff to include hyphens in the library ID matching:
- private static final Pattern LOG_PATTERN = Pattern.compile("([\\w.]+)\\.(\\d+:\\d+-\\d+:\\d+)\\(\\d+\\):\\s*(\\{\\}|[^\\s]+)"); + private static final Pattern LOG_PATTERN = Pattern.compile("([\\w.\\-]+)\\.(\\d+:\\d+-\\d+:\\d+)\\(\\d+\\):\\s*(\\{\\}|[^\\s]+)");
48-53: Use Appropriate Logging Level for Detailed CQL OutputsThe logging statements between lines 48 and 53 output detailed CQL information using
logger.info. To prevent cluttering production logs and adhere to best practices, consider changing the logging level todebug.Apply this diff to adjust the logging levels:
- logger.info("CQL DEBUG: libraryId={}, range={}, output={}, cql-definition={}", libraryId, range, output, definition); + logger.debug("CQL DEBUG: libraryId={}, range={}, output={}, cql-definition={}", libraryId, range, output, definition); - logger.info("CQL DEBUG: libraryId={}, range={}, output={}, cql=\n{}", libraryId, range, output, cql); + logger.debug("CQL DEBUG: libraryId={}, range={}, output={}, cql=\n{}", libraryId, range, output, cql); - logger.info("CQL DEBUG: libraryId={}, range={}, output={}", libraryId, range, output); + logger.debug("CQL DEBUG: libraryId={}, range={}, output={}", libraryId, range, output);Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/utils/CqlUtils.java (1)
39-39: Specify Character Encoding When Converting Byte Array to StringWhen converting
content.getData()to aString, the character encoding is not specified. This may lead to inconsistencies across different systems. It's advisable to specifyStandardCharsets.UTF_8explicitly.Apply this change to specify the character encoding:
- .map(content -> new String(content.getData())) + .map(content -> new String(content.getData(), StandardCharsets.UTF_8))Ensure to import the required class:
import java.nio.charset.StandardCharsets;Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/utils/ApplicationContextProvider.java (1)
7-19: Consider alternative approaches to static ApplicationContext accessWhile the implementation works, using a static field to store ApplicationContext can lead to several issues:
- Testing becomes difficult as the static context persists between tests
- Memory leaks can occur if the context isn't properly cleared
- Thread safety concerns with the static field
- Potential NullPointerException in getApplicationContext()
Consider these alternatives:
- Inject dependencies directly where needed using Spring's DI
- If static access is necessary:
- Add null checks
- Clear context on application shutdown
- Use thread-safe initialization
Example implementation:
@Component public class ApplicationContextProvider implements ApplicationContextAware, DisposableBean { private static volatile ApplicationContext context; public static ApplicationContext getApplicationContext() { if (context == null) { throw new IllegalStateException("ApplicationContext not initialized"); } return context; } @Override public synchronized void setApplicationContext(ApplicationContext applicationContext) { context = applicationContext; } @Override public void destroy() { context = null; } }Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/configs/LinkConfig.java (1)
19-19: Add documentation and validation for the cqlDebug configurationThe new configuration property would benefit from:
- Documentation explaining its purpose and impact
- Validation if needed in certain environments
Consider adding:
+ /** + * Enables detailed CQL evaluation debugging output. + * When true, additional logging will be generated during measure evaluation. + * Should be used carefully in production as it may impact performance. + */ private boolean cqlDebug = false;Java/measureeval/src/main/resources/logback-spring.xml (1)
45-47: Consider adding STDOUT appender for local debuggingThe CQL debug logger only uses the custom appender. For local development and debugging, it might be helpful to also include the STDOUT appender.
<logger name="org.opencds.cqf.cql.engine.debug.DebugUtilities" level="DEBUG" additivity="false"> <appender-ref ref="cql"/> + <appender-ref ref="STDOUT"/> </logger>docs/README.md (2)
52-56: Add security considerations for Kafka authenticationThe Kafka authentication table should include security best practices and warnings about credential handling.
Add a note about secure credential management:
| spring.kafka.properties.security.protocol | SASL_PLAINTEXT | + +> **Security Note**: Never commit credentials directly in configuration files. Use environment variables or secure secret management solutions.
62-62: Enhance Azure App Config documentationThe note about Azure App Config precedence could be more detailed to help developers understand the configuration resolution order.
Add configuration precedence order:
-Note: If a Java service is configured to use Azure App Config, keys in ACA take precedence over Java VM args _and_ Environment Variables. +Note: Configuration resolution order when Azure App Config is enabled: +1. Azure App Config keys (highest precedence) +2. Java VM arguments +3. Environment Variables (lowest precedence)docs/service_specs/measure_eval.md (2)

100-101: Enhance API documentation for debug parametersThe documentation for debug-related endpoints could be more detailed to better support the debuggability improvements.
Add parameter details:
-| **POST /api/measure-definition/{id}/$evaluate**: Evaluates a measure against clinical data provided in the request body. May include a `debug` flag that indicates to create cql debug logs on the service during evaluation. -| **GET /api/measure-definition/{id}/{library-id}/$cql**: Retrieves the CQL for a specific measure definition and library.

Java/measureeval/src/main/resources/application.yml (1)
54-54: LGTM! Good security practice with default value.
The addition of cql-debug: false follows Spring Boot configuration conventions and safely defaults to disabled, which is appropriate for a debugging feature.
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/repositories/LinkInMemoryFhirRepository.java (1)
1-10: LGTM! Clean class structure and imports.
The class appropriately extends InMemoryFhirRepository and includes only the necessary imports.

10-10: Verify CqlLogAppender implementation and consider adding configuration properties
The custom appender lacks configuration properties which might affect its behavior and log formatting consistency.
Let's check the implementation of CqlLogAppender:
13-15: LGTM! Configuration aligns with debugging requirements
The CQL debug logger configuration is well-structured with appropriate debug level and prevents log duplication with additivity=false.
Let's verify the debug utilities class exists and is properly used:
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/controllers/MeasureDefinitionController.java (2)
104-123: New Endpoint for Retrieving CQL Added Successfully
The addition of the getMeasureLibraryCQL method effectively provides the functionality to retrieve CQL content for a measure definition's library. The input validation and exception handling are appropriately handled.
128-131: Debug Parameter Integrated into Evaluate Method Successfully
Incorporating the debug parameter into the evaluate method enhances flexibility by allowing users to enable CQL debugging information during evaluation.
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/services/MeasureEvaluator.java (1)
78-85: Addition of compileAndEvaluate Method Enhances Functionality
The new compileAndEvaluate static method provides a streamlined approach to compiling and evaluating measures with specified parameters and a debug flag. This enhancement improves code clarity and usability.
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/services/MeasureEvaluatorCache.java (1)
19-22: LGTM: Constructor properly initialized with required dependencies

13-13: Verify CqlLogAppender configuration requirements
The new CQL appender is added without any configuration properties. Please verify if the CqlLogAppender class requires any specific properties for proper initialization.
Consider adding documentation comments to explain the purpose and behavior of this custom appender.
✅ Verification successful
CqlLogAppender implementation is correctly configured
The CqlLogAppender is a simple appender that extends AppenderBase<ILoggingEvent> and doesn't require any additional configuration properties. It processes CQL-related log messages by extracting and formatting specific components (libraryId, range, and output) using pattern matching. The current configuration in logback-spring.xml is sufficient for its operation.

72-111: Standardize pipeline file extensionsThere's an inconsistency in the file extensions used for pipeline definitions:
- Most files use
.yaml- Some files use
.yml(e.g.,azure-pipelines.shared.cd.yml,deploy_tags_all.yml)Consider standardizing all pipeline files to use the same extension for better maintainability.
109-110: Consider reorganizing deployment orchestration filesThe deployment orchestration files (
deploy_all_services.yamlanddeploy_tags_all.yml) could be better organized:
- Consider creating a dedicated

53-61: Consider adding security best practices for credential management.While the documentation clearly explains the Kafka authentication configuration, it would be beneficial to add a note about secure credential management, especially for production environments. Consider mentioning that sensitive credentials should be managed through secure configuration management systems rather than directly in VM arguments.
These properties can be applied when running/debugging the services locally by passing them as VM arguments, such as `-Dspring.kafka.properties.sasl.mechanism=PLAIN`. + +> **Security Note:** For production environments, sensitive credentials should be managed through secure configuration management systems (e.g., Azure Key Vault, environment variables, or other secure credential stores) rather than directly in VM arguments.
63-65: Enhance Azure App Config documentation clarity.The current note about configuration precedence could be improved by:
- Avoiding the undefined abbreviation "ACA"
- Providing the complete configuration precedence order

6-6: LGTM: Clean import additions and field annotation
The addition of LinkInMemoryFhirRepository import and @Getter annotation on the bundle field are good improvements that align with the PR's objectives.
Also applies to: 9-9, 32-33
95-102: LGTM: Well-structured static factory method
The new compileAndEvaluate method provides a clean interface for measure evaluation with proper parameter handling using ParametersUtils.

The switch to LinkInMemoryFhirRepository may have implications on resource handling. Please ensure comprehensive testing covers this change.
✅ Verification successful
Repository change is safe to proceed
The switch from InMemoryFhirRepository to LinkInMemoryFhirRepository is a safe change as:
LinkInMemoryFhirRepositoryis a direct subclass ofInMemoryFhirRepository- It maintains the same constructor signatures and only adds a specialized transaction handling
- The change is minimal and backward compatible with the base functionality
- The override is defensive, only handling specific Bundle cases while preserving default behavior

✅ Verification successful
The change to localhost listeners is safe and correctly configured
Based on the analysis of the docker-compose.yml file, the change from 0.0.0.0 to 127.0.0.1 for Kafka listeners is safe because:
- All services are configured to connect to Kafka using
kafka_b:9094(the EXTERNAL listener) rather than the localhost listeners - The Kafka broker configuration correctly advertises:
- Internal communication on
SASL_PLAINTEXT://127.0.0.1:9092 - Controller communication on
CONTROLLER://127.0.0.1:9093 - External service communication on
EXTERNAL://kafka_b:9094
- Internal communication on

145-147: Verify performance impact of disabling caching.
The comment indicates that measure compilation happens on every request to handle debug flag changes. Consider:
- Performance impact of disabling caching
- Alternative approaches like cache key including debug flag
Consider these alternatives to improve performance while maintaining debug capability:
- Use composite cache key:
measureId + "_" + debug - Maintain separate cache instances for debug/non-debug
- Add cache warmup for frequently accessed measures
✅ Verification successful
Let me gather more information about the caching implementation and measure evaluation.
Let me check the MeasureEvaluatorCache implementation to understand the current caching strategy.
Disabling caching for debug mode is a valid design choice
After analyzing the codebase, I can see that:
- The codebase already has a
MeasureEvaluatorCacheservice that caches compiled measures usingConcurrentHashMap - The decision to bypass cache for debug mode is intentional, as debug flags affect CQL execution logging
- The cache is still used for non-debug evaluations through the
evaluatorCache.get()method - The performance impact is limited to debug-mode evaluations only, which are typically not used in production
The current implementation provides a good balance between performance (caching for normal operations) and debugging capabilities (fresh compilation when debug is needed).

I'm gonna have to test again. I tested against the CLI early on... Maybe I broke something in the process.

- Point CLI to logback-cli.xml. - Introduce explicit dependency for library resolution.

5-7: Consider adding JavaDocs or a clear explanation of expected usage.By documenting how the
resolvemethod behaves when the library is not found or thelibraryIdis invalid, developers can more easily rely on this interface in various contexts.Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/services/MeasureEvaluatorCache.java (1)
41-50: Beware of potential performance impacts.The
resolvemethod iterates over all cached measure evaluators looking for a matching library. If there are numerous measure definitions, this could become inefficient. Consider indexing or otherwise centralizing library retrieval to avoid scanning each measure evaluator’s bundle in a loop.Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/utils/CqlUtils.java (1)
26-32: Clarify error handling approach for missing libraries.The method throws
NotFoundExceptionfrom Javassist, but also referencesResponseStatusExceptionin other areas.

105-129: Enhance API documentation and error handlingThe new CQL endpoint could benefit from:
- More detailed API documentation
- Structured error responses
- Input validation messages

134-148: Consider caching implications of debug parameterThe evaluate method's changes introduce potential caching considerations:
- Debug parameter affects caching strategy
- Potential performance impact of recompilation
Consider implementing a composite cache key that includes the debug flag to avoid unnecessary recompilations while maintaining the desired debugging capability.

Learning: In `Java/measureeval/src/main/resources/logback-cli.xml`, it is acceptable to have the logger for `com.lantanagroup.link` without an appender reference.

Learning: In `CqlLogAppender.java`, the `groupResources` method does not require additional safeguards for resource count or parsing because the grouping will always produce a smaller output than the original log's resource enumeration.

29-33: Validate non-null parameters in the bean method.
If measureEvaluatorCache is null (for example, due to a wiring issue or misconfiguration), starting the log appender might fail. Consider adding an assertion or defensive check to gracefully handle that scenario.
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/services/MeasureEvaluatorCache.java (2)
19-24: Ensure that linkConfig is not null during instantiation.
Since linkConfig is used in further operations (e.g., toggling CQL debug), consider adding a null check or using constructor validation to prevent NullPointerExceptions.
33-33: Validate debug compilation impact on caching.
Using this.linkConfig.isCqlDebug() during compilation means switching between debug/non-debug modes could potentially reuse cached measure evaluators in ways that might be unintended. If that is indeed a concern, you may wish to address it. Otherwise, the current approach is acceptable.
Java/measureeval/src/main/java/com/lantanagroup/link/measureeval/utils/CqlUtils.java (2)
10-24: Verify library URL matching logic.
Relying on .endsWith("/" + libraryId) could lead to unexpected matches if library IDs are substrings of one another. Consider a stricter matching approach (e.g., exact equality on the library’s getUrl() or parsing libraryId from the URL).
34-49: Review the use of ResponseStatusException for library content not found.
Raising an HTTP-driven exception is appropriate in a REST context, but if this utility is used in non-HTTP workflows (e.g., batch or Kafka consumers), you may wish to handle missing content differently (e.g., custom exceptions or logs).

50-51: Add a brief introduction to the Java section.Consider adding a short overview paragraph explaining what configurations are covered in this section and why they're important for Java services.
## Java + +This section covers important configuration aspects specific to Link's Java-based services, including authentication and configuration management.
52-63: Enhance security-related documentation for Kafka authentication.While the configuration is well documented, consider adding:
- A note about secure credential management
- Environment-specific configuration recommendations
These properties can be applied when running/debugging the services locally by passing them as VM arguments, such as `-Dspring.kafka.properties.sasl.mechanism=PLAIN`. + +> **Security Note:** In production environments, avoid passing credentials through VM arguments. Instead, use secure configuration management solutions like Azure Key Vault or environment variables managed by your deployment platform.
64-66: Expand Azure App Config documentation with examples and best practices.The current documentation could be more helpful with:
- Examples of common configuration scenarios
- Best practices for managing configurations across environments
- Troubleshooting tips for precedence-related issues
### Azure App Config Note: If a Java service is configured to use Azure App Config, keys in ACA take precedence over Java VM args _and_ Environment Variables. + +#### Configuration Precedence Example + +Given the same configuration key: +1. Azure App Config: `my.config=value1` +2. VM argument: `-Dmy.config=value2` +3. Environment variable: `MY_CONFIG=value3` + +The service will use `value1` from Azure App Config. + +#### Best Practices +- Use Azure App Config for environment-specific configurations +- Reserve VM arguments for local development and debugging +- Document service-specific configuration keys in your service's README

48-49: LGTM! Clear documentation of Swagger JSON endpoints.
The addition of Java service Swagger JSON endpoint information complements the existing documentation well.
🛠️ Description of Changes
This is considered TECH DEBT because the core/underlying functionality is not meaningfully modified. The changes here are intended to provide better documentation and better support for debugging when measure evaluation doesn't return the expected results.
cqlDebugconfiguration property for enhanced debugging.🧪 Testing Performed
Ran the measureeval service locally and used the REST API to invoke $evaluate to ensure the evaluator still functioned correctly.
Ran the FileSystemInvocation class from the command line to test evaluation against other measures.
📓 Documentation Updated
Updated the measureeval service spec document to bring it up-to-date; it looks like it was already inaccurately describing the service's configuration. Added notes about the additional "cql debugging" functionality that's now available.
