How We Built a Serverless Backend Using GraalVM, AWS Lambda and Astra DB (Part 2)

• serverless-astra-graalvm

  2 1 6.0 Java

  Sample serverless order processing API using DataStax Astra Serverless and AWS Lambda.

  

We can now focus on the third goal: implementing the Lambda function and running it inside a GraalVM native image runtime. We’ll also hook it up to API Gateway, so that the end user can call it via an HTTP API. The complete source code is available on GitHub.

• Gson

  27 22,981 9.1 Java

  A Java serialization/deserialization library to convert Java Objects into JSON and back

  

For more information on native-image build arguments, please consult the GraalVM Native Image Options documentation. The next listing contains the contents of reflect.json, which contains a bunch of data classes that we need to serialize and deserialize with Gson, as well as our Lambda handler class which the runtime needs to instantiate based on the qualified class name passed to the Lambda function.

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• terraform

  501 41,235 9.9 Go

  Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

  

In order to create our infrastructure, we are using Terraform. Terraform is also used to create our Astra DB instance using the DataStax Astra Provider, but we’ll not discuss it in this post. Please check out the blog post, Let’s Get Started With Terraform for Astra DB, for more information on the DataStax Astra Provider.

• Graal

  156 19,807 10.0 Java

  GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

  

We can now focus on the third goal: implementing the Lambda function and running it inside a GraalVM native image runtime. We’ll also hook it up to API Gateway, so that the end user can call it via an HTTP API. The complete source code is available on GitHub.

• maven-mvnd

  82 2,745 7.6 Java

  Apache Maven Daemon

  

We’re going to use Maven as our build tool, and we’ll combine the following Maven plugins and dependencies to generate the runtime package:
