Overview

‘timeuuid` columns are a special type of UUID column that support time-based queries. For instance, a `timeuuid` clustering column can be filtered by ranges of times into which the UUIDs must fall. This functionality presumes the use of type 1 UUIDs, which encode the timestamp of their creation.
