1.53

Summary

In this release we improved our Idempotency utility and storage layer is now faster and cheaper by leveraging conditional writes. We also made important changes to the Logger and Metrics utility.

Special thanks to @j-d-ha for reporting logging issues and @sdangol for their first contribution to the project.

Logging

Docs

We've enhanced the AddPowertoolsLogger method with improved service registration and added automatic ILogger interface registration. A new ClearExistingProviders option is now available to prevent multiple logger providers.

builder.Logging.AddPowertoolsLogger(config =>
{
    config.Service = "TestService";
    config.LoggerOutputCase = LoggerOutputCase.PascalCase;
}, clearExistingProviders: true);

Metrics

Docs

Before this release, if you published invalid metrics they could fail silently, leading to data loss. Now Lambda will raise an exception if the following constraints do not hold:

• Metric Name: Validated according to CloudWatch constraints
• Metric Value: Validated for numeric values
• Metric Unit: Validated for allowed units
• Metric Resolution: Validated for allowed resolutions
• Dimension Name: Both Dimension name and value are validated for non empty, non-null values.

Idempotency

Docs

Several months ago AWS introduced support for ReturnValuesOnConditionCheckFailure, a feature designed to streamline conditional write operations and reducing costs in Amazon DynamoDB. With this enhancement, Powertools for AWS Lambda now optimistically attempts to write items to DynamoDB. If the item already exists, it seamlessly returns it without requiring an additional operation.
