Describe the bug

We are seeing an issue with hanging dynamo queries when using the ClusterDaxAsyncClient.

I do not have steps to reproduce or much in the way of specific additional information because we are still in the early stages of addressing this issue. It is fairly complex and difficult to isolate and reproduce. However I am not looking for specific help with this bug at this time. I am really just looking for some clarification here: is it possible that this bug we are facing, similar to the one seen in this older ticket, might be happening because the dax library is using an older dynamodb dependency?

#3652

Apparently, in order to use a dax cluster for dynamo queries in Java, one cannot just use the aws sdk. Instead one must use a largely (completely?) undocumented Amazon Dax Java Client, which I have found here: https://mvnrepository.com/artifact/software.amazon.dax/amazon-dax-client. The latest release for this library is 2.0.4, released a little over a year ago. There appears to be no documentation of any kind that I can see online for this client. However it appears that this library is using dynamoDB version 2.16.91, whereas the ticket above indicates that the hanging request issue was fixed in version 2.20.68.

Is there a better place to request help information on this issue, given that this dax library is not, for some reason, part of the aws sdk? Does anyone know if this dax library is still supported? Will it receive updates to use more recent versions of the sdk? Also, if someone knows where documentation for it might exist, I would be very grateful.

Engaging AWS support with these questions instead. That will be a better venue for this. Sorry for the clutter.
