HintedHandOffManager
The hint schema looks like this:
CREATE TABLE hints (
target_id uuid,
hint_id timeuuid,
message_version int,
mutation blob,
PRIMARY KEY (target_id, hint_id, message_version)
) WITH COMPACT STORAGE;
Thus, for each node in the cluster we treat its uuid as the partition key; each hint is a logical row
(physical composite column) containing the mutation to replay and associated metadata.
