AWS Data Exchange now supports automatic exports of third-party data updates

AWS Data Exchange subscribers can now use auto-export to automatically copy newly published revisions from their 3rd party data subscriptions to an Amazon S3 bucket of their choice in just a few clicks. With auto-export, subscribers no longer have to manually export new revisions or dedicate engineering resources to build ingestion pipelines that export new revisions as soon as they are published. For data subscribers that manage frequent updates to their file-based 3rd party data, auto-export saves significant time and effort.

You’re invited to the Google Smart Home Developer Summit

Google Smart Home Developer Summit

Today there are over 276 million smart home households globally, and the industry continues to see rapid growth every year. Users have never been more comfortable bringing home new smart home devices — but they also continue to expect more from their devices, and their smart homes. To meet and exceed these expectations, we want to make sure developers have the tools and support to build their best experience across the Google Home app, Nest, Android, and Assistant.

That’s why we’re excited to announce the return of the Google Smart Home Developer Summit on October 21, 2021! This year’s event is free to join, fully virtual and will be hosted on our website with broadcast times available for our developer communities in the AMER, EMEA, and APAC regions.

To kick things off, Michele Turner, Senior Director of Product for Google’s Smart Home Ecosystem, will share our vision for the home and preview upcoming tools and features to build your next devices and apps using Matter and Thread — technologies transforming the industry. This will be followed by a developer keynote to dig deeper into announcements, and a round of technical sessions, workshops, and more, hosted by Google’s smart home leaders.

Building the best smart home platform means using trusted technology and intelligence to develop your integrations faster, provide tools to drive your innovation, and allow you new paths to growth. We can’t wait to engage with you and share more about how we can lead and grow the smart home together.

You can register for the Google Smart Home Developer Summit 2021 here, and follow along with the event using the tag #GoogleHomeSummit on social media. We hope to see you there!

Amazon Redshift launches RA3.xlplus in AWS GovCloud (US) Regions

Amazon Redshift RA3.xlplus nodes are now available in the AWS GovCloud (US) Regions. Amazon Redshift RA3 instances with managed storage allow you to scale compute and storage independently for fast query performance and lower costs. RA3 is available in three different node types to allow you to balance price and performance depending upon your workload requirements. RA3.xlplus nodes offer one-third compute (4 vCPU) and memory (32 GiB) compared to RA3.4xlarge at one-third of the price. RA3 nodes are built on the AWS Nitro System and feature high bandwidth networking and large high-performance SSDs as local caches.

Achieve up to 34% better price/performance with AWS Lambda Functions powered by AWS Graviton2 processor

AWS Lambda functions powered by next-generation AWS Graviton2 processors are now generally available. Graviton2 functions, using an Arm-based processor architecture, are designed to deliver up to 19% better performance at 20% lower cost for a variety of Serverless workloads, such as web and mobile backends, data, and media processing. With lower latency and better performance, functions powered by AWS Graviton2 processors are ideal for powering mission critical Serverless applications.

Mark your calendars: Android Dev Summit, Chrome Dev Summit and Firebase Summit are coming your way in a few weeks!

Posted by the Google Developer Team

Developers: it’s time to start marking your calendars, we’re hard at work on a busy slate of summits coming your way in just a few weeks. Here’s a quick rundown of three summits we just announced this week:

  • Android Dev Summit: October 27-28
  • Chrome Dev Summit: November 3
  • Firebase Summit: November 10

Android Dev Summit is back, October 27-28

Directly from the team who builds Android, the Android Dev Summit returns this year on October 27-28. Join us to hear about the latest updates in Android development, centered on this year’s theme: excellent apps, across devices. We have over 30 sessions on a range of technical Android development topics. Plus, we’ve assembled the team that builds Android to get your burning #AskAndroid questions answered live. Interested in learning more? Be sure to sign up for updates through our Android newsletter here.

Discover, Connect, Inspire at Chrome Dev Summit 2021

The countdown to Chrome Dev Summit 2021 is on — and we can’t wait to share what we have in store. We’ll kick things off on November 3 by sharing the latest product updates in our keynote and hosting a live ask me anything (AMA) with Chrome leaders. You’ll also have the chance to chat live with Googlers and developers around the world, participate in workshops with industry experts, attend interactive learning lounges to consult with engineers in a group setting, and receive personalized support during one-on-one office hours. Everyone can tune into the keynote and AMA, but space is limited for the workshops, office hours, and learning lounges. Request an invite to secure your spot — we’ll see you on November 3!

And follow the Firebase Twitter channel for more updates on Firebase Summit, which will be coming to you on November 10!

How to use App Engine push queues in Flask apps

Since its original launch in 2008, many of the core Google App Engine services such as Datastore, Memcache, and Blobstore, have matured to become their own standalone products: for example, Cloud Datastore, Cloud Memorystore, and Cloud Storage, respectively. The same is true for App Engine Task Queues with Cloud Tasks. Today’s Module 7 episode of Serverless Migration Station reviews how App Engine push tasks work, by adding this feature to an existing App Engine ndb Flask app.

That app is where we left off at the end of Module 1, migrating its web framework from App Engine webapp2 to Flask. The app registers web page visits, creating a Datastore Entity for each. After a new record is created, the ten most recent visits are displayed to the end-user. If the app only shows the latest visits, there is no reason to keep older visits, so the Module 7 exercise adds a push task that deletes all visits older than the oldest one shown. Tasks execute asynchronously outside the normal application flow.

Key updates

The following are the changes being made to the application:

  1. Add use of App Engine Task Queues (taskqueue) API
  2. Determine oldest visit displayed, logging and saving that timestamp
  3. Create task to delete old visits
  4. Update web page template to display timestamp threshold
  5. Log how many and which visits (by Entity ID) are deleted

Except for #4 which occurs in the HTML template file, these updates are reflected in the “diff”s for the main application file:

With these changes implemented, the web app now shows the end-user which visits will be deleted by the new push task:

Next steps

To do this exercise yourself, check out our corresponding codelab which leads you step-by-step through the process. You can use this in addition to the video, which can provide guidance. You can also review the push queue documentation for more information. Arriving at a fully-functioning Module 7 app featuring App Engine push tasks sets the stage for migrating it to Cloud Tasks (and Cloud NDB) ahead in Module 8.

All migration modules, their videos (when available), codelab tutorials, and source code, can be found in the migration repo. While the content focuses initially on Python users, we will cover other legacy runtimes soon so stay tuned.
