AWS Lambda Java Runtime

# Introduction

Serverless computing is getting more and more popular. One of the cloud providers supporting 31 | a service like this is AWS, and the corresponding AWS Lambda service.

Java is a great language to write scalable and maintainable applications. However, for 32 | serverless computing it was not the best choice because of slow cold-starts. Until now.

With this customized runtime, you can speed up your Java Lambda functions. Instead of 33 | spinning up a full JVM in AWS Lambda, it's possible to use GraalVM and compile a standalone 34 | native executable and run it without any additional overhead.

# Quickstart

For now, the quickstart can be found on my blog: Tackling Java cold startup times on AWS Lambda with GraalVM (opens new window).

# Solution

The boostrap file has CRLF instead of LF. Convert the line endings, and re-upload the package.

# Unable to create Proxy class

This indicates you are using an old version (< 4.5.8) of Apache http client. It is recommended to use http client version >= 4.5.9 to avoid the breaking change introduced in apache client 4.5.7 and the latency in exception handling.

# Solution

When building with GraalVM, the classes are pre-compiled into the executable. In case of interface-based runtime proxies, 79 | GraalVM should know which interfaces will be implemented by the proxy class.

This can be configured via the proxy-config.json file within META-INF/native-image/... folder.

Example configuration for the AWS DynamoDB SDK:

[
 80 |   ["org.apache.http.conn.HttpClientConnectionManager", "org.apache.http.pool.ConnPoolControl", "com.amazonaws.http.conn.Wrapped"],
 81 |   ["org.apache.http.conn.ConnectionRequest", "com.amazonaws.http.conn.Wrapped"]
 82 | ]

# Solution

In case of the application using any type of reflection to access a class, GraalVM will not know about it 130 | during AoT compilation. It needs to be told what these classes are in a file called reflect-config.json within the 131 | META-INF/native-image/... folder.

Example configuration:

[
132 |   ...
133 |   {
134 |     "name": "com.sun.crypto.provider.HmacCore$HmacSHA256",
135 |     "allDeclaredFields": true,
136 |     "allDeclaredConstructors": true,
137 |     "allDeclaredMethods": true,
138 |     "allDeclaredClasses": true
139 |   },
140 |   ...
141 | ]

One of the cloud providers supporting 3 | a service like this is AWS, and the corresponding AWS Lambda service. 4 | 5 | Java is a great language to write scalable and maintainable applications. However, for 6 | serverless computing it was not the best choice because of slow cold-starts. Until now. 7 | 8 | With this customized runtime, you can speed up your Java Lambda functions. Instead of 9 | spinning up a full JVM in AWS Lambda, it's possible to use GraalVM and compile a standalone 10 | native executable and run it without any additional overhead. 11 | 12 | ## Quickstart 13 | For now, the quickstart can be found on my blog: [Tackling Java cold startup times on AWS Lambda with GraalVM](https://arnoldgalovics.com/tackling-java-cold-startup-times-on-aws-lambda-with-graalvm/). -------------------------------------------------------------------------------- /src-docs/src/troubleshooting/README.md: -------------------------------------------------------------------------------- 1 | # Troubleshooting 2 | ## The Lambda function is reporting Runtime.InvalidEntrypoint 3 | ### Symptom 4 | ```text 5 | { 6 | "errorMessage": "RequestId: 8ba2e00d-c988-4304-a84e-6bd8801c510f Error: fork/exec /var/task/bootstrap: no such file or directory", 7 | "errorType": "Runtime.InvalidEntrypoint" 8 | } 9 | 10 | START RequestId: 8ba2e00d-c988-4304-a84e-6bd8801c510f Version: $LATEST 11 | END RequestId: 8ba2e00d-c988-4304-a84e-6bd8801c510f 12 | REPORT RequestId: 8ba2e00d-c988-4304-a84e-6bd8801c510f Duration: 0.69 ms Billed Duration: 1 ms Memory Size: 128 MB Max Memory Used: 5 MB 13 | RequestId: 8ba2e00d-c988-4304-a84e-6bd8801c510f Error: fork/exec /var/task/bootstrap: no such file or directory 14 | Runtime.InvalidEntrypoint 15 | ``` 16 | ### Solution 17 | The `boostrap` file has CRLF instead of LF.
