is.codion.framework.lambda.LambdaEntityHandler
All Implemented Interfaces:
com.amazonaws.services.lambda.runtime.RequestHandler<com.amazonaws.services.lambda.runtime.events.APIGatewayV2HTTPEvent,com.amazonaws.services.lambda.runtime.events.APIGatewayV2HTTPResponse>
public class LambdaEntityHandler extends Object implements com.amazonaws.services.lambda.runtime.RequestHandler<com.amazonaws.services.lambda.runtime.events.APIGatewayV2HTTPEvent,com.amazonaws.services.lambda.runtime.events.APIGatewayV2HTTPResponse>
AWS Lambda handler that implements the Codion entity protocol using EntityServer.

This implementation creates a local EntityServer instance and delegates all entity operations to it. The EntityServer handles authentication, connection pooling, transaction management, and all other complex server-side logic.

To deploy this handler directly: 

 aws lambda create-function \
   --handler is.codion.framework.lambda.LambdaEntityHandler::handleRequest \
   --runtime java21

Configuration: Use JAVA_TOOL_OPTIONS environment variable to set system properties: 

 JAVA_TOOL_OPTIONS="-Dcodion.db.url=jdbc:postgresql://host/db -Dcodion.server.idleConnectionTimeout=10"
