benchmarks/600.java/601.hello-world/java/src/main/java/faas/App.java (3)
1-1
: Consider using a more specific package name.The current package name
faas
is concise but might be too generic. To provide better context and avoid potential conflicts, consider using a more specific package name that reflects the project structure or purpose, such ascom.spcl.serverlessbenchmarks.java.helloworld
.
3-3
: Consider using a more descriptive class name.While
App
is a common name for main application classes, it might be too generic for a benchmark-specific application. Consider using a more descriptive name that reflects the purpose of this benchmark, such asHelloWorldBenchmark
orJavaFunctionBenchmark
.
1-7
: Summary: Good start, but room for improvementOverall, this file provides a basic starting point for Java benchmarks in the serverless framework. However, there are several areas where it could be improved to better serve its purpose:
- The package name could be more specific.
- The class name could be more descriptive.
- The main method could include more benchmark-specific functionality.
These changes would make the code more robust and better suited for benchmarking purposes.
Would you like assistance in implementing these suggestions or in developing more advanced benchmarking features for this Java function?
dockerfiles/openwhisk/java/Dockerfile.function (3)
1-3
: LGTM with a suggestion for optimizationThe base image setup looks good. Using a build argument for the base image provides flexibility for different environments or versions.
However, consider optimizing the
COPY
command to only include necessary files for the function, rather than copying the entire context. This can reduce the image size and build time.You could update the
COPY
command to be more specific, for example:COPY pom.xml /function/ COPY src /function/srcThis assumes your Java source files are in a
src
directory. Adjust the paths as needed for your project structure.
7-8
: LGTM with a suggestion for improved readabilityThe Maven build process is well-implemented. The conditional check for
pom.xml
is a good practice to avoid errors if the file is missing.To improve readability, consider breaking the long RUN command into multiple lines:
RUN if [ -f ./pom.xml ]; then \ mvn clean install; \ else \ echo "pom.xml not found, aborting build." && exit 1; \ fiThis multi-line format is easier to read and maintain, especially if you need to add more complex logic in the future.
1-8
: Overall, the Dockerfile is well-structured with room for minor improvementsThe Dockerfile successfully sets up a build environment for Java functions in OpenWhisk. It uses a flexible base image, installs the necessary build tools (Maven), and attempts to build the project conditionally.
A few suggestions for improvement:
- Optimize the COPY command to only include necessary files.
- Clean up the apt cache after installing Maven to reduce image size.
- Improve readability of the conditional Maven build command.
Also, note that this Dockerfile doesn't specify an ENTRYPOINT or CMD. This might be intentional if it's meant to be extended, but ensure this aligns with your intended use in the OpenWhisk environment.
Consider documenting the expected usage of this Dockerfile, especially if it's intended to be extended or used as part of a multi-stage build process. This will help other developers understand its purpose and how to properly use or modify it.
benchmarks/600.java/601.hello-world/java/pom.xml (2)
8-12
: Consider revising the groupId and artifactId.While the version and packaging are appropriate, there are some concerns with the project coordinates:
- The groupId "faas" is unusually short and doesn't follow the reverse domain name convention (e.g., com.company.project).
- The artifactId "601.hello-world" includes a number prefix, which is unconventional and may cause issues with some tools.
Consider revising these to more standard formats:
- groupId: e.g., "com.spcl.serverlessbenchmarks"
- artifactId: e.g., "hello-world-java"
1-38
: Summary: Basic Maven configuration in place, with room for improvements.The pom.xml file provides a functional Maven configuration for a Java project. However, there are several areas where it could be improved to align better with best practices and provide a more robust setup:
- Revise the groupId and artifactId to follow standard conventions.
- Consider updating to a more recent Java version.
- Update the maven-jar-plugin to the latest version.
- Review the main class package name for better alignment with Java conventions.
- Consider adding necessary dependencies if the project requires any external libraries.
These changes will enhance the project structure, maintainability, and potentially performance.

: Remove unused importThe
Gson
class is imported but never used in the code. Consider removing this unused import to keep the code clean.Apply this diff to remove the unused import:
-import com.google.gson.JsonObject;
10-17
: Remove commented-out code and unused variable
The commented-out logger setup is not being used. If logging is not required, remove these comments to improve code readability.
The
Gson
instance is created but never used in the code. Remove it to avoid confusion and potential performance impact.Apply this diff to clean up the code:
- // Logger logger = Logger.getLogger(FunctionHandler.class.getName()); - // logger.setLevel(Level.INFO); - - Gson gson = new Gson(); App function = new App();
1-55
: Overall assessment and remaining concernsThe
Main
class provides a good structure for handling serverless function invocations, including timing the execution and detecting cold starts. However, there are a few areas that could be improved:
- Error handling: Consider adding more robust error handling throughout the class, especially for the
App.handler
call.- Cold start detection: The current method using file I/O might not be reliable in all serverless environments. Consider using a more robust method.
- Code cleanliness: Remove unused imports and commented-out code to improve readability.
- Performance: Ensure that the
App
instance is created efficiently, possibly as a static field if it's thread-safe, to avoid unnecessary object creation on each invocation.To improve the overall design:
- Consider extracting the cold start detection logic into a separate method or class for better modularity.
- If possible, make the
App
class conform to a specific interface that defines thehandler
method, allowing for easier testing and potential dependency injection.- Consider adding logging throughout the class to aid in debugging and monitoring in a production environment.
These changes will make the code more robust, maintainable, and performant in a serverless environment.

: Java configuration for OpenWhisk looks good, with some suggestions for improvement.The new Java configuration for OpenWhisk is well-structured and consistent with other language configurations. It aligns with the PR objective of adding Java support. Here are some observations and suggestions:
- The base image, deployment files, and Minio package inclusion are appropriate for a Java application in OpenWhisk.
- Consider adding support for newer Java versions (e.g., Java 11, 17) to provide more options for users.
- Verify if Minio version 8.5.9 is the latest stable version compatible with Java 8. If not, consider updating to the latest compatible version.
- Evaluate if any additional Java-specific packages or configurations are needed for optimal performance in OpenWhisk.
Would you like assistance in expanding the Java version support or verifying the Minio version compatibility?

: LGTM: Java support added to Runtime.deserializeThe addition of Java to the languages dictionary in Runtime.deserialize is correct and consistent with the existing structure.
Consider refactoring this method to use a more dynamic approach for language mapping. This could make it easier to add new languages in the future without modifying this method. For example:
@staticmethod def deserialize(config: dict) -> Runtime: try: language = Language[config["language"].upper()] except KeyError: raise ValueError(f"Unsupported language: {config['language']}") return Runtime(language=language, version=config["version"])This approach would automatically work for any language added to the Language enum without requiring changes to this method.
Java support is not fully integrated across the codebase
Several parts of the project still have hardcoded language checks limited to Python and Node.js. To ensure consistent Java support, please update the following files to include Java where applicable:
sebs.py
install.py
scripts/run_experiments.py

: Summary: Java support added to CLIThe change successfully adds Java as a language option in the CLI, which is a crucial first step in supporting Java benchmarks in the SeBS framework. This modification aligns well with the PR objectives.
However, it's important to note that this change only affects the CLI interface. To ensure full Java support, other parts of the system (such as benchmark configurations, deployment logic, and result processing) may need to be updated as well. These updates might be present in other files or could be part of future PRs.
Consider creating a checklist or documentation for adding new language support to ensure all necessary components are updated consistently across the system.

🛠️ Refactor suggestion
Refine the output message and consider adding benchmark-specific functionality.
-
The current output "Hellooooooooooooooooooo, World!" seems unusual for a standard "Hello, World!" program. Consider using a more conventional "Hello, World!" message unless there's a specific reason for the extended greeting.
-
For benchmarking purposes, consider adding more functionality to this method. Some suggestions:
- Add a parameter to control the number of times the message is printed.
- Include a simple computation to measure performance.
- Add timing code to measure execution time.
- Implement logging to capture benchmark results.
Here's an example of how you might modify the method:
public static void main(String[] args) {
int iterations = args.length > 0 ? Integer.parseInt(args[0]) : 1;
long startTime = System.nanoTime();
for (int i = 0; i < iterations; i++) {
System.out.println("Hello, World!");
}
long endTime = System.nanoTime();
long duration = (endTime - startTime) / 1_000_000; // Convert to milliseconds
System.out.printf("Executed %d iterations in %d ms%n", iterations, duration);
}
This modification allows for multiple iterations and includes basic timing, which could be useful for benchmarking purposes.

Optimize Maven installation to reduce image size
The Maven installation step is correct, but it can be optimized to reduce the final image size.
Consider updating the Maven installation command to clean up the apt cache:
RUN apt-get update && \
apt-get install -y maven && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*
This will remove unnecessary package files after installation, resulting in a smaller image size.

Consider updating to a more recent Java version.
The project is currently configured to use Java 8 (1.8) for both source and target compatibility. While Java 8 is still widely used, it's becoming outdated. Consider updating to a more recent LTS version like Java 11 or 17 to benefit from performance improvements and newer language features.
To update, you would change these lines:
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
Or for Java 17:
<maven.compiler.source>17</maven.compiler.source>

Review security settings and sensitive information handling
The deployment configuration for OpenWhisk is comprehensive. However, there are some security considerations to address:
- The
wskBypassSecurity
is set to "true". This could pose a security risk if used in a production environment. - Sensitive information fields (Docker registry credentials, storage access keys) are left empty. Ensure you have a secure method to populate these fields in different environments.
Consider the following improvements:
- Set
wskBypassSecurity
tofalse
unless absolutely necessary for testing purposes. - Implement a secure method to inject sensitive information (e.g., environment variables, secrets management system) rather than hardcoding them in the configuration file.
- Add a comment in the file to indicate how sensitive information should be handled.
Example:
"wskBypassSecurity": false,
// ... other fields ...
"docker_registry": {
"registry": "", // Set via DOCKER_REGISTRY env var
"username": "", // Set via DOCKER_USERNAME env var
"password": "" // Set via DOCKER_PASSWORD env var

🛠️ Refactor suggestion
Improve cold start detection mechanism
The current implementation of cold start detection has a few potential issues:
- The file path "/cold_run" might not be writable in all environments.
- The error handling for file creation only prints the stack trace, which might not be visible in some serverless environments.
- This approach may not accurately detect cold starts in all scenarios, especially if the container is reused but the file is deleted.
Consider the following improvements:
- Use a more reliable method for cold start detection, such as caching a static variable or using environment variables specific to your serverless platform.
- If you must use a file-based approach, use a path that's guaranteed to be writable, such as
/tmp/cold_run
. - Improve error handling to log errors properly and potentially set
isCold
to true if file creation fails.
Here's an example of how you might refactor this:
private static boolean isFirstExecution = true;
// In the main method:
boolean isCold = isFirstExecution;
if (isFirstExecution) {
isFirstExecution = false;
}
This approach uses a static variable to detect the first execution, which is typically equivalent to a cold start in serverless environments.

- There's a typo in the variable name when adding the request ID to the result.
- The method for adding properties to the JsonObject is incorrect. Java's JsonObject uses
addProperty
instead ofput
.
Apply the following changes to fix these issues:
- JsonObject jsonResult = new JsonObject();
- jsonObject.put("begin", formattedBegin);
- jsonObject.put("end", formattedEnd);
- jsonObject.put("request_id", "requestId");
- jsonObject.put("compute_time", computeTime);
- jsonObject.put("is_cold", isCold);
- jsonObject.put("result", result);
+ JsonObject jsonResult = new JsonObject();
+ jsonResult.addProperty("begin", formattedBegin);
+ jsonResult.addProperty("end", formattedEnd);
+ jsonResult.addProperty("request_id", requestId);
+ jsonResult.addProperty("compute_time", computeTime);
+ jsonResult.addProperty("is_cold", isCold);
+ jsonResult.add("result", result);
return jsonResult;
Note that for the "result" field, we use add
instead of addProperty
because result
is itself a JsonObject.

Potential Inconsistencies: Missing "java" in Other Language Options
Several files still list only "python" and "nodejs" as language options. Please update the following files to include "java":
tools/build_docker_images.py
scripts/run_experiments.py
tests/aws/create_function.py
dockerfiles/local/runner.py
🔗 Analysis chain
LGTM: Java language support added
The change adds "java" as an option for the --language
parameter, which is consistent with the PR objective of adding Java support to the SeBS framework.
To ensure this change is properly integrated, let's verify if there are any other parts of the code that might need updates to support Java:
🏁 Scripts executed

Incorrect dependency handling: Appending to 'requirements.txt' in Java project
The add_deployment_package_java
method appends Java packages to requirements.txt
, which is used for Python dependencies. In Java Maven projects, dependencies should be managed through the pom.xml
file, not requirements.txt
.
Consider modifying the method to add the deployment packages to the pom.xml
file by updating the ``` section accordingly.

Improve indentation, comments, and error handling in the Java source copying logic
The indentation of comments is inconsistent, which can affect readability. Additionally, it's advisable to check if the source directory exists before attempting to copy it, to avoid potential exceptions if the directory doesn't exist.
Apply this diff to correct the issues:
# copy src folder of java (Java benchmarks are Maven projects and need directories)
if self.language_name == "java":
output_src_dir = os.path.join(output_dir, "src")
# If src dir in output exists, remove the directory and all its contents
if os.path.exists(output_src_dir):
shutil.rmtree(output_src_dir)
src_dir = os.path.join(path, "src")
# Check if src directory exists in the benchmark path
+ if os.path.exists(src_dir):
shutil.copytree(src_dir, output_src_dir)

@mahlashrifi This does not look correct - requirements.txt
should only be used for Python projects. In Python, we add packages needed for specific functions to this file such that pip
installs them.
Shouldn't we use something else for Java?

We should use /tmp/cold_run

Dockerfile is very good :-) But we should also be able to deploy the code as zip package; particularly for cloud platforms that do not support containers (Azure, GCP). Can you add that or should I take a look into that?
