We’re excited to announce that AWS SDK for Java 2.x (model 2.16.1 or later) now has out-of-the-box assist for GraalVM Native Image compilation.
GraalVM is a common digital machine that helps JVM-based languages (e.g. Java, Scala, Kotlin), dynamic languages (e.g. Python, JavaScript), and LLVM-based languages (e.g. C, C++). GraalVM Native Picture is likely one of the hottest options that GraalVM gives. It permits Forward-of-Time (AoT) compilation of Java applications right into a self-contained native executable, referred to as a local picture. The executable is optimized and accommodates all the pieces wanted to run the applying, and it has sooner startup time and smaller heap reminiscence footprint in contrast with a JVM. Subsequently, native pictures are well-suited for serverless functions the place startup latency is crucial.
We in contrast the startup efficiency of the executable created from GraalVM native picture with the identical software working on JVM. The take a look at software creates an S3Client with ApacheHttpClient and sends a easy GetObjectRequest. In our testing, we measured the SDK 2.x startup time and the primary request latency in addition to the reminiscence utilization. The outcomes point out that the native picture has considerably sooner startup and decrease reminiscence consumption.
As a result of nature of AoT, options that depend on dynamic class loading, proxies, or reflections have to be recognized at construct time and require particular assist. For instance, the lessons use reflections have to be registered within the native picture configuration information. The newest Java SDK 2.x accommodates such configurations required for SDK lessons, and it’s able to be constructed right into a native picture.
The newest launch additionally features a new Maven Archetype, archetype-app-quickstart, that allows you to shortly bootstrap a native-image appropriate Java software configured with the AWS SDK for Java 2.x as a dependency. On this weblog, we are going to present you find out how to use the archetype to create a brand new software with GraalVM Native picture assist.
Getting Began
Conditions
This put up assumes you will have some familiarity with Java programming, the Maven construct system, and the GraalVM runtime. To make use of this tutorial, it’s worthwhile to have the next software program put in:
Java 8+
Apache Maven
GraalVM 21.0.0+
GraalVM Native Picture
Producing the applying
To generate a venture, open a terminal (command line) window, run mvn archetype:generate with archetype-app-quickstart. The model of the archetype is similar because the Java SDK 2.x model, and you need to use the most recent model. There are two modes you’ll be able to select: interactive mode and batch mode.
In interactive mode, you’ll be prompted to supply required properties, separately.
mvn archetype:generate -DarchetypeGroupId=software program.amazon.awssdk -DarchetypeArtifactId=archetype-app-quickstart -DarchetypeVersion=2.16.1
In batch mode, it’s worthwhile to present all required properties without delay. Under is the checklist of the required properties and you may try all obtainable choices right here.
Required Properties
-
- service: the service consumer for use within the lambda perform, eg: s3, dynamodb. Just one service needs to be offered.
- groupId: the Maven group ID of the applying
- artifactId: the Maven artifact ID of you software
- httpClient: specifies the http consumer for use by the SDK consumer. Obtainable choices are
url-connection-client(sync),apache-client(sync) andnetty-nio-client(async). - nativeImage: specifies whether or not GraalVM Native Picture configuration needs to be included
mvn archetype:generate
-DarchetypeGroupId=software program.amazon.awssdk
-DarchetypeArtifactId=archetype-app-quickstart
-DarchetypeVersion=2.16.1
-DgroupId=com.take a look at
-DartifactId=sample-project
-Dservice=s3
-DhttpClient=apache-client
-DnativeImage=true
-Dregion=us-west-2
-DinteractiveMode=false
The generated software has a dependency of AWS SDK for Java 2.16.1. The output will likely be one thing like this

When the archetype:generate aim completes, you should have a Maven venture with the construction as follows
sample-project
├── README.md
├── pom.xml
└── src

└── HandlerTest.java
The App.java class is the entry level for the applying. The DependencyFactory.java class accommodates the configured SDK consumer.
Constructing the applying
To construct the applying, run the next instructions:
# Go to venture listing created. # The identify needs to be the identical because the artifactId offered cd sample-project # Construct the applying mvn clear bundle
Making a native executable
You’ll be able to run the next command to create a local picture:
mvn clear bundle -P native-image
As soon as it completes, it can generate an executable within the goal folder. The identify needs to be the identical because the artifactId offered.

Operating the native executable
To execute the native picture, you’ll be able to run the next command
goal/sample-project
The output needs to be much like the next:

Conclusion
On this weblog put up we confirmed you the advantages of utilizing native picture compiled of functions utilizing the AWS SDK for Java 2x. We additionally confirmed you the way fast it’s to make use of the brand new archetype to get begin with native-image appropriate functions utilizing AWS SDK for Java 2.x. If you wish to study extra concerning the archetype, you’ll be able to try the archetype-app-quickstart supply code on GitHub. Please give this new archetype a try to tell us what you assume through the GitHub points web page.
