Does the Lambda , AWS Active MQ support Message Groups ?

Question

I want to use a single Active MQ  Queue and have it invoke lambda functions.  I want to enforce order but also have parallelism.   Active MQ has a concept of "Message Groups" which sounds perfect.    Does the AWS lambda support Message Groups and will invoke different instance of lambda synchronously with different message groups as required  based on load ?

Answer

To answer my own question,  the AcitveMQ  Message Group is irrelevant as the documentation says

"The Lambda service limits the concurrency to one execution environment per queue." see 
https://aws.amazon.com/blogs/compute/using-amazon-mq-as-an-event-source-for-aws-lambda/

As such there will never be more than one lambda function being executed at one time as part of a synchronous call, as no no matter whether the Message Group is specified there will not be any opportunity to increase the amount of concurrent processing.
