Trying to query public parameters in AWS SSM, I see that Amazon Keyspaces (for Apache Cassandra) is missing from the value of /aws/service/global-infrastructure/services and /aws/service/global-infrastructure/regions/us-east-1/services.
I query these params both using the Go SDK and the AWS CLI, e.g.:
aws ssm get-parameters-by-path --path "/aws/service/global-infrastructure/regions/us-east-1/services"
aws ssm get-parameters-by-path --path "/aws/service/global-infrastructure/services"
I do get a valid response, but Amazon Keyspaces is not there.
