![]() ![]() It’s a best practice to remove the Apache and Netty HTTP clients from your deployment package if they’re not required for your use case. Note: The AWS Java SDK 2.0 includes the Apache HTTP client and Netty HTTP client by default, along with the Java HTTP URL Connection client. Bu program Java programlama dilinde yazlmtr ve Euro deerini Dolar deerine çevirir. Update to AWS Java SDK 2.0įor more information, see Tuning the AWS Java SDK 2.x to reduce startup time. If you don’t specify configuration variables in your code, it takes Lambda more time to discover the default variables for your function.įor more information, see the Function code section of Best practices for working with AWS Lambda functions. Setting your function’s configuration parameters in advance reduces your function’s invocation and duration latency. Set your Lambda function’s configuration parameters in advance Download /aspectWeaver: The dynamic aspect weaver (AOP) described in the article Runtime performance of invokedynamic : Evaluation through a Java library /. Reducing the size of your deployment package to its runtime necessities reduces the amount of time that it takes to invoke your function.įor more information, see Best practices for working with AWS Lambda functions. Reduce the number of classes in your application Avoid reflective operations in sections of code that are called frequently. Reflective operations have slower performance than their non-reflective counterparts. ![]() Reduce reflective operations in your Lambda code If the call fails, make sure that you catch the error. Note: Dummy calls to lazily loaded libraries can fail if Lambda doesn't have the information required for a successful API call. These dummy calls initialize the libraries and prewarm the SDK that you're using. To avoid lazy loading of libraries during initialization, you can make dummy API calls to any lazily loaded libraries outside of the function handler. Make API calls to any lazily loaded libraries outside of the function handler This static initialization allows these resources to be initialized once per sandbox and then reused for all future invocations in the execution environment.įor more information, see Optimizing static initialization.
