Support for AWS Managed Cassandra missing data types

[twstewart42]

AWS recently released a managed cassandra service. We've tried to hook kairsodb up to MCS but got stuck with errors for unsupported data types, Frozen and static. We were unable to do any testing beyond this with KairosDB.

https://docs.aws.amazon.com/mcs/latest/devguide/cassandra-apis.html

Would it be possible to create row_keys and service_index without frozen and static data types?

"  tags frozen<map<text, text>>,\n" +
"  mtime timeuuid static,\n" +

Error when connecting to MCS

[Thread-1] ERROR [Main.java:398] - Shutdown exception:
com.google.inject.ProvisionException: Unable to provision, see the following errors:

1. Error in custom provider, com.datastax.driver.core.exceptions.InvalidQueryException: org.apache.cassandra.db.marshal.FrozenType(org.apache.cassandra.db.marshal.MapType(org.apache.cassandra.db.marshal.UTF8Type,org.apache.cassandra.db.marshal.UTF8Type)) type is not supported for PRIMARY KEY part tags

The static mtime allows me to know when the last time a partition was updated, this is for the service key stuff.

The frozen map is required in order to use the map as a clustering column. What does MCS offer in order to replace these?
