Class DurableConfig

java.lang.Object
software.amazon.lambda.durable.DurableConfig
public final class DurableConfig extends Object
Configuration for DurableHandler initialization. This class provides a builder pattern for configuring SDK components including LambdaClient, SerDes, and ExecutorService.

Configuration is initialized once during Lambda cold start and remains immutable throughout the execution lifecycle.

Example usage with default settings: 


 @Override
 protected DurableConfig createConfiguration() {
     return DurableConfig.builder()
         .withDurableExecutionClient(customClient)
         .withSerDes(customSerDes)
         .build();
 }

Example usage with custom Lambda client: 


 @Override
 protected DurableConfig createConfiguration() {
     LambdaClient lambdaClient = LambdaClient.builder()
         .region(Region.US_WEST_2)
         .credentialsProvider(ProfileCredentialsProvider.create("my-profile"))
         .build();

     return DurableConfig.builder()
         .withLambdaClient(lambdaClient)
         .build();
 }
