feature request: support for the new SNS PublishBatch API

[alexwlchan]

Is there an existing issue for this?

Feature description

AWS recently announced a new PublishBatch API for SNS, which allows you to send up to 10 messages in a single API request. It'd be good to have that API in LocalStack.

🧑‍💻 Implementation

There's already an SNS implementation in LocalStack, so I assume this involves adding a new API to that.

Anything else?

API reference: https://docs.aws.amazon.com/sns/latest/api/API_PublishBatch.html

+1 ... use localstack heavily for development and ran into this error message today when attempting to implement the new PublishBatch API:

InternalFailure: API action 'PublishBatch' for service 'sns' not yet implemented

+1, code tested on AWS cannot be used, as integration tests make use of localstack. Same error:

API action 'PublishBatch' for service 'sns' not yet implemented

Is it already in the latest release ? I could not find it.

Thanks for the pointer @liviu-bot . Looks like we've had a small hickup in our CI pipeline. The build on master is now running again - you can follow the progress here. The latest image should become available in ~40mins from now. Apologies for the confusion!
