v2.10.0

Summary

This release brings support for parsing S3 Event Notifications via EventBridge and support for custom properties on the ActiveMQ event source data class.

⭐️ Huge thanks for our first-time contributors @alexaiss and @ivica-k, and also @tibbe for the typing hot-fix!

Parsing S3 event notifications via EventBridge

Docs

Amazon S3 can send event notifications with Amazon EventBridge. We added support for parsing those events in Lambda using the new S3EventNotificationEventBridgeModel.

Thank you @robert-malai for capturing this feature gap!

Custom properties on ActiveMQ event

When integrating with Active MQ, Lambda supports JMS custom properties. After this change, you can also access them when using the ActiveMQ event source data class.

v2.9.0

Summary

This release contains a new feature on Batch Processing, along with enhancements and bug fixes to Logger and Feature Flags utilities.

⭐ Huge welcome to the new contributors: @royygael, @iago1460

SQS FIFO Batch Processing

Docs

You can now use SQS FIFO queues with the Batch Processing utility. We stop processing messages after the first failure and return all failed and unprocessed messages natively. This helps preserve the ordering of messages in your queue.

⭐ Thanks to @whoDoneItAgain for reporting this feature gap.

Logger improvements

We now allow exception and exception_name attributes as extra fields in all logging levels. Previously, we dropped those attributes in non-error logging levels (e.g: INFO).

⭐ Thanks to @iago1460 for reporting this bug and submitting the fix!

New community content

Finally, we have two new community posts on Feature Flags from @ran-isenberg:

• How CyberArk uses Powertools to implement Feature Flags with AWS AppConfig: link
• A talk about the added value of using feature flags as part of your CI/CD process and how AWS Lambda Powertools can help: link

v2.8.0

Summary

This release is packed with new features and enhancements, specifically to Batch Processing, Metrics and Idempotency utility.

⭐ Huge welcome to new contributors: @BakasuraRCE, @prudnikov, @kavichu, @marcraminv

High-concurrency async processor

Docs

Thanks to @BakasuraRCE, we’re adding a new specialized processor for high concurrency jobs that can process thousands of messages sub-second (thanks to @sthulb for load testing) - AsyncBatchProcessor and async_batch_processor.

These will use Python’s asyncio.gather to call your record handler with all records at the same time. During load testing, we’ve managed to process 5500 messages in approximately 300ms compared to 1.2 seconds with BatchProcessor synchronous counterpart.

1-second resolution metrics

Docs

You can now create high-resolution (1s) metrics that are common for use cases like IoT, telemetry, time-series, real-time incident, etc. Previously, metrics were only created with 60-second resolution. This is an opt-in feature.

Inheriting dimensions in single_metric

Docs

Thanks to @prudnikov, you can now optionally set default dimensions for single metrics. These are individual application or operational metrics that despite being isolated from a larger set of metrics, they do share the same set of dimensions (avoid repetition, sparse metrics).

Idempotent_function decorator is now thread-safe

Thanks to @mploski, any Python function decorated with idempotent_function can now safely be called from threads. Previously, we used to create higher-level AWS SDK clients which didn’t support threading - calling functions decorated back then could result in unforeseen side-effects.

Example

import os
import time
from concurrent.futures import ThreadPoolExecutor, as_completed
from threading import current_thread

from aws_lambda_powertools.utilities.idempotency import (
    DynamoDBPersistenceLayer,
    idempotent_function,
)

TABLE_NAME = os.getenv("IdempotencyTable", "")
persistence_layer = DynamoDBPersistenceLayer(table_name=TABLE_NAME)
threads_count = 2


@idempotent_function(persistence_store=persistence_layer, data_keyword_argument="record")
def record_handler(record):
    time_now = time.time()
    return {"thread_name": current_thread().name, "time": str(time_now)}


def lambda_handler(event, context):
    with ThreadPoolExecutor(max_workers=threads_count) as executor:
        futures = [executor.submit(record_handler, **{"record": event}) for _ in range(threads_count)]

    return [
        {"state": future._state, "exception": future.exception(), "output": future.result()}
        for future in as_completed(futures)
    ]

v2.7.0

Summary

This release adds support for time-based Feature Flags, and simplified support for returning a custom HTTP status code on the event handler.

Feature Flags

Docs

This release enhanced the Feature Flags utility with a new time-based feature. You can now enable certain features in your application during the weekends, at a certain period or day, across one or more time zones. Big thanks to @ran-isenberg! Check out this sample that enables a feature on weekends in NYC TZ:

Event Handler

Docs

We also have a nice addition to our event handler utility. You can now add a second return argument if you want to customize the returned HTTP status code. ⭐ Big thanks to @theoutsider24 for your first contribution! ⭐

v2.6.0

Summary

In this release, we added new specialised routers for all supported event handlers. This way you'll get type hints from your IDE as you access the current_event property.

We also improved the exception logging in the idempotency utility with additional context taken from the raised downstream exception.

⭐ Finally, we thank our two new contributors @aidansteele and @pawosty for helping us iron out some important bugs! ⭐

v2.5.0

Summary

This release improves logging incoming events that might be wrapped in common containers such as Event Source Data Classes, Pydantic/Parser BaseModels, and Dataclasses.

Also we addressed an issue when a header is set explicit to None.

Big thanks to @jasmarc for the bug report!

Example:

import json

from aws_lambda_powertools.event_handler import (
    APIGatewayRestResolver,
    Response,
)

app = APIGatewayRestResolver()

@app.get("/none")
def hello():
    headers = {"This-Header-Will-Be-Omitted": None}
    response = {"hello": "world"}
    return Response(body=json.dumps(response), headers=headers, status_code=200)


def lambda_handler(event, context):
    return app.resolve(event, context)

v2.4.0

Summary

This release introduces a brand new streaming utility to handle datasets larger than the available memory.

This addresses scenarios where you want to process Amazon S3 objects as seekable data streams, with minimal memory consumption.

Built-in data transformations

Docs

We've added support for popular data transformations to decompress and deserialize data (gzip, CSV and ZIP). This way you can transform the data while streaming, and only use the minimum amount of memory necessary.

Bring your own data transformation

Docs

You can also create your own data transformations and add them to the pipeline. For example, here's how to use the ijson library to parse JSON as a data stream:

We plan to support more data transformations in the future too!

🌟 Would you like to see a specific data transformation supported in Powertools? Drop us a line in the python channel of our Discord.

v2.3.1

Summary

This patch release address an issue in Event Handler REST API to support dynamic routes with an equal sign (=).

Big thanks to @baraksalomon for the bug report!

Previously, a dynamic route containing = would result in a not found response (HTTP 404).

Example

from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools.utilities.typing import LambdaContext

app = APIGatewayRestResolver()

# NOTE: `/token/bXl0b2tlbg==` should be matched and not return 404 now
@app.get("/token/<token>")
def get_token(token: str):
    return {"received": f"{token}"}


def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)
