We would also be interested in running Temporal with AWS Keyspaces.
At this moment I have found this issue in the Cadence repository that invalidates this possibility: https://github.com/uber/cadence/issues/3427
@maxim,
Do you have plans to make Temporal support AWS Keyspaces?
At this moment is seems that the missing feature in Keyspaces is batching LWTs. Are you aware of any other missing features that Temporal makes use of? We would like to make a request to AWS to add the features required by Temporal to Keyspaces, hence the interest in the missing features.
EDIT:
There is another thread open that answers the support question: Running on Amazon Keyspaces
