Bump software.amazon.lambda:powertools-cloudformation from 2.3.0 to 2.4.0

[dependabot]

Bumps software.amazon.lambda:powertools-cloudformation from 2.3.0 to 2.4.0.

Release notes

Sourced from software.amazon.lambda:powertools-cloudformation's releases.

v2.4.0

Summary

We are excited to announce a new feature in Logger: Logger buffering. This new feature allows you to buffer logs for a specific invocation, and flush them automatically on error or manually as needed.

We also added GraalVM support for CloudFormation and Idempotency utilities, expanding native compilation capabilities for better performance and reduced cold start times.

⭐️ Thanks to @​ConnorKirk, @​aryannikhil, and @​kjswaruph for their first-time contributions to this release!

New Log Buffering feature

Docs

You can now enable log buffering by configuring the BufferingAppender in your logging configuration. This feature allows you to:

• Buffer logs at the WARNING, INFO, and DEBUG levels
• Automatically flush logs on error or manually as needed
• Reduce CloudWatch costs by decreasing the number of emitted log messages

public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
@Logging
public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
LOGGER.debug(&quot;Processing payment&quot;);  // this is buffered
LOGGER.info(&quot;Payment validation complete&quot;);  // this is not buffered
LOGGER.error(&amp;quot;Payment failed&amp;quot;);  // this will flush the buffer automatically

return new APIGatewayProxyResponseEvent().withStatusCode(500);

}

}

Configuration options

Log buffering is configured through your logging framework configuration (Log4j2 or Logback) using the BufferingAppender:

Option	Description	Default
maxBytes	Maximum size of the buffer in bytes	20480
bufferAtVerbosity	Minimum log level to buffer (more verbose levels are also buffered)	DEBUG
flushOnErrorLog	Whether to flush buffer when an error is logged	true

When log buffering is enabled, you can use the @Logging annotation with flushBufferOnUncaughtError = true to automatically flush the buffer when an uncaught exception occurs. This enables you to have detailed logs from your application when you need them the most.

Here is an example log4j2.xml configuration:
