In our testing we are seeing significant allocation reduction for JSON based services like DynamoDB and SQS.

For the DynamoDB Native AOT changes I saw with the code below my cold start improve from 1,700 ms to 500 ms by using Native AOT with the DynamoDB high level libraries.

RT @davidpallmann: Did you know you can use .NET Aspire with AWS to build cloud-native applications? I'm excited to be presenting ".NET As…

Last week the AWS .NET SDK updated data integrity checks for S3. The changes are transparent to existing code but if you are using S3 emulators you might run into problems. The announcement below has the details and how disable if you need to.

Isn't GitHub being down like a snow day and we give up on work and go outside?

First year not going to reinvent so I actually had time to do the Seattle marathon.

@wjaxxx As far as managed runtimes go Lambda only supports LTS versions of languages. You can use .NET 9 as a self contained or Native AOT function.

@johnzabroski @beeradmoore @vlahunter My limited understanding of this site is it uses a simple hello world function to test. SnapStart isn't going to be a good fit there because there is roughly a flat time spent restoring the Snapshot. Functions that have cold starts greater then that flat time see the benefit.

@Kralizek We haven't done anything with deployment and Aspire yet. So yes when you deploy your application to ECS you would need to include the collector container. I assume you would use the AWS Distro for OpenTelemetry.

@Kralizek @davidfowl Awesome!

@Kralizek There is also a hook you can register off of SnapshotRestore that runs during restore if you need to refresh the state of anything as part of restoration.

@Kralizek It includes the constructor where you can register snapshot hooks off of Amazon.Lambda.Core.SnapshotRestore type. Best practice is to use the hooks to warm up as much of the .NET codebase while the Snapshot is being created to avoid work being done during restore.

@brendonparker @qidydl That is great, thanks for sharing.

@brendonparker @qidydl In a larger application the important thing is to try and warm up as much of the .NET code as possible before the ");" call. That will run during the snapshotting process and avoid having to run during the cold start restore.

@bslatner @bslatner Just realized you responded to the PowerShell preview blog post but I assume your question was directed to the Lambda SnapStart post.
