v2.11.0

[heitorlessa]

Summary

This release adds support for S3 Event Notifications via EventBridge in Event Source Data Classes, and a bug fix for Feature Flags to handle falsy context values correctly.

⭐ Huge welcome to new contributors: @ajwad-shaikh and @ivica-k

S3 Event Notifications via EventBridge

Docs

A new use case is to process S3 Events with the newer and faster EventBridge integration. Previously, EventBridge integration with S3 would use CloudTrail leading up to a few minutes delays.

With the new integration, there is a slightly new payload that we had to support in order to ease that integration.

Thanks to @ivica-k, you can now use S3EventBridgeNotificationEvent!

from aws_lambda_powertools.utilities.data_classes import S3EventBridgeNotificationEvent, event_source
from aws_lambda_powertools.utilities.typing import LambdaContext


@event_source(data_class=S3EventBridgeNotificationEvent)
def lambda_handler(event: S3EventBridgeNotificationEvent, context: LambdaContext):
    bucket_name = event.detail.bucket.name
    file_key = event.detail.object.key
    new_storage_class = event.detail.destination_storage_class
    ...

Fixing falsy values in Feature Flags

Thanks to @ajwad-shaikh for reporting and fixing this bug (incl. @ran-isenberg), you can now handle flag variants when their context values are falsy, e.g., empty lists, empty strings, False, 0, etc.

Example that wasn't possible before this release

Flag

{
  "sales_offer": {
    "default": false,
    "rules": {
      "unpaid_users": {
        "when_match": true,
        "conditions": [ {"action": "EQUALS", "key": "is_paid", "value": 0} ]
      }
   }
}

Context

{
   "is_paid": 0,
}
