やろうとしたこと

以下のようなコードで長めのAWS LambdaをJavaから実行しようとした。

val invokeRequest = InvokeRequest()
        .withFunctionName(FUNCTION_NAME)
        .withPayload("適当なpayload")
        .withInvocationType(InvocationType.RequestResponse)
val lambdaClient = AWSLambdaClientBuilder.standard()
        .withRegion(REGION)
        .withCredentials(AWSStaticCredentialsProvider(credentials)).build()
val invokeResult = lambdaClient.invoke(invokeRequest) // ここでTooManyRequestsException

解決

AWSLambdaClientBuilder#withClientConfiguration()でタイムアウトを設定

val invokeRequest = InvokeRequest()
        .withFunctionName(FUNCTION_NAME)
        .withPayload("適当なpayload")
        .withInvocationType(InvocationType.RequestResponse)
val lambdaClient = AWSLambdaClientBuilder.standard()
        .withRegion(REGION)
         // ↓これを追加
        .withClientConfiguration(ClientConfigurationFactory().config.withSocketTimeout(TIMEOUT))
        .withCredentials(AWSStaticCredentialsProvider(credentials)).build()
val invokeResult = lambdaClient.invoke(invokeRequest)

InvokeRequest#withSdkClientExecutionTimeout() とかInvokeRequest#withSdkRequestTimeout()とかそれっぽいのもあったけどそれらは反映されなかった。。
